Turn into a "green" Chengdu to continue to fight and reduce waste and defend the defense

"哐哐 一", an empty bucket, with the oil stains and pollutants contaminated by the chemical industry, is put into the green waste container production line of the body. Crusted into long strip -like iron; a row of empty barrels, which are neatly used in the central comprehensive use of the workshop. They come from different factories and enterprises, but they have the same name- "dangerous waste".

What is dangerous waste? How to deal with it in danger? With the problem, the reporter walked into the Chengdu Harm Treatment Center in Sichuan Province in Longquan Mountain.

[Four ways]

Incineration, materialization, stability/curing landfill, comprehensive utilization

Automatic operation improves the safety of hazardous waste treatment

Drive all the way to the east and pass through a slightly winding Panshan Highway. The Chengdu Chengdu Lightworm Disposal Center is located where the mountains are surrounded by mountains.

Different from imagination, there is no scorching smell produced by the odor or incineration of organic matter here. If it is not a few huge workshops, it is difficult for the "focusing on the development of the development of the hazardous waste industry to promote the improvement of the ecological environment". Link it here with the Harbin Waste Treatment Center.

"Dangerous waste is included in the national hazardous waste list or the dangerous characteristics of dangerous characteristics identified in accordance with the national regulations." Behind him, the machine sounded, but he couldn't see a lot of workers. "The equipment in the workshop is remotely operated through the control room, and the degree of automation of hazardous waste treatment is relatively high. This control is more accurate and the operation is more secure and environmentally friendly." Wan Qian introduced it.

Regarding how to identify the treatment of each hazardous waste, thousands of money also gives us the answer -hazardous waste storage is stored in a specific packaging container, and then transported to a hazardous waste disposal center through hazardous waste transportation vehicles. Before dealing with the site of the customer's abilities, we understand the basic situation of hazardous waste, including the category of hazardous waste, chemical safety technology instructions (MSDS), production technology, etc., and will compare and screen the obtained hazardous information.

At present, there are four "packages" in the project of Chengdu, the Chengdu hazardous waste disposal center in Sichuan Province, which are incineration, materialized treatment, stability/curing landfill treatment, and comprehensive utilization.

Terminal products after hazardous waste disposal, such as fly ash, residue, heavy metal sludge, etc., will be sent to a safe landfill after stability/curing treatment. At first glance, it looks like a "large puddle" without water, but there are actually many articles in the seemingly unpretentious "puddle". "This terrain can not only be diverted by the HDPE film covered by the top of the land, and can effectively prevent dust." Wan Qian introduced that the landfills here are very different from the ordinary garbage landfill. A total of 11 floors of the anti -seepage structure of the field, a total of 7 floors of the anti -osmosis structure of the slope. This anti -osmogenetic structure effectively reduces the generation of landfill penetration. In addition, 6 groundwater monitoring wells are set up around the landfill, which is regularly set up. Monitor water quality, thereby protecting groundwater and soil from hazardous violations. "

【Two types of conversion】

Incinement steam generates electrical energy

Use the packaging items before using it

In July, the daily maximum temperature in Chengdu is above 35 ° C. Longquan Mountain Green Linsen cannot stop the heat waves. The temperature next to the incineration furnace of the hazardous waste disposal center is hotter.

Concentrated incineration of hazardous waste is an important part of the treatment link. Can it be transformed to the thermal value of organic matter in hazardous waste, so as to achieve comprehensive utilization of resources, energy conservation and emission reduction, and promoting sustainable economic development? In response, the hazardous waste disposal center built the residual heat power generation project next to the incineration center control room.

The reporter saw that multiple pipes were connected to the residual heat recovery system from top to bottom. "The high -temperature flue gas generated by the hazardous waste incineration conducts heat exchange in the remaining heat boiler, and generates overheating steam, which will promote the generated power generated by the generator set." Introduction For exhaust gas, waste residue, dust and other harmful gases, it has achieved good results since it was launched on March 24.

In addition to the transformation of power, the dangerous waste disposal center is also increasing the reuse of some hazardous waste resources.

In the comprehensive use of the workshop, a group of iron buckets of a batch of iron packaging containers are waiting for cleaning and disposal, and workers are busy production in special protection measures. "These packaging materials that are contaminated with toxic or corrosive waste need to be cleaned through process before entering the next process of processing." Ten money pointed to the color iron barrel wrapped in the plastic film in the workshop, 200 liters and above, more than 200 liters and above, The following renewable packaging buckets are mainly used for re -packaging and use of hazardous wastes such as the original and auxiliary materials of general industrial enterprises, and general chemical industry such as production enterprises. 4 cm of metal blocks and plastic blocks are sold for steelmaking and regenerative plastic companies as raw materials for waste metals and waste plastics.

Accelerating the process of hazardous waste resources, at present, the Chengdu Longquan Construction waste resource utilization center is under construction. After completion, it is expected to dispose of 1.5 million tons/year of construction waste. The implementation of 'double carbon' strategy. "Wan Qian said.

【A target】

100%safe utilization disposal in the city's dangerous waste

Implement the "white list" system for hazardous waste transfer

Focus on the ecological base of the urban ecology of the thick plantation park, resolutely fight the blue water, blue sky, the pure soldiers, and the defense of waste reduction, and strive to make the good ecological environment the goal of the most inclusive people's livelihood and well -being. Established 27 hazardous waste business units. Among them, there are 2 hazardous waste disposal units, 10 comprehensive utilization units of hazardous waste, and 15 hazardous waste collection units. The city's solid waste reduction, resource, and harmless levels have been comprehensively improved, ensuring 100%safety utilization disposal and environmental safety in the city. Continue to implement the Law on the Continuation of Solid Waste Pollution Environmental Prevention, and earnestly fulfill the functions of hazardous waste supervision and management. Yang Yong, head of the Soil and Solid waste Chemical Department of the Municipal Ecological and Environment Bureau, told reporters that at present, Chengdu is accelerating Pengzhou, Chongzhou, Jianyang, etc. The construction of six hazardous waste facilities under construction ensures the completion and operation at the end of 2023. It can add 140,000 tons/year to use the disposal capacity.

"At the end of 2023, the construction of 12 hazardous wastes was completed to collect storage facilities, and the centralized collection of hazardous waste for small and medium -sized enterprises could be added, which can add 60,000 tons/year of hazardous waste collection capacity. After completion, it can further effectively ensure the economic and social development of the city. Abolition reduction and comprehensive utilization. "Yang Yong said.

At the same time, a series of cross -regional cooperation is also underway for the efficient treatment of hazardous waste. In March of this year, Sichuan and Chongfeng signed a cooperation agreement to jointly promote the construction of the "non -waste city" in the Shuangcheng Economic Circle in Chengdu and Chongqing. The two places have innovated the cooperation system for hazardous waste transfer.

Together with green and low -carbon development, build beautiful mountains and rivers and lakes. The reporter learned that in the next step, Sichuan and Chongfeng will promote pollution and defense co -governance from four aspects: co -construction ecological barrier, co -administrative cross -border pollution, co -business environmental management, and green development. Specifically, it includes strengthening the supervision of natural protection for natural protection and ecological protection in adjacent areas, promoting cross -border watershed ecological environmental protection collaborative governance and joint defense treatment, deepening ecological environmental protection supervision linkage and legislative judicial protection collaboration, and co -construction of green low -carbon technology innovation Platform, green city standardization technology support platform and other measures.
