In the past ten years, the resourceization rate of old Hong Kong domestic waste disposal has increased from 10%to 68%

As the world's largest resource, ecological, and intelligent solid waste comprehensive disposal base in domestic waste, the old port base undertakes 50%of Shanghai's solid waste terminal treatment and resource -based. The disposal of domestic waste is about 12,500 tons/day.

In order to further improve Shanghai's domestic waste treatment capacity and accelerate the construction of the old port base treatment facilities and environmental improvement project construction, from 2010 to 2020, it is a period of rapid construction of the old port base to improve the ability of the end. Nearly 10 major engineering construction tasks were completed. At this stage, the resourceization rate of base garbage disposal of the base increased from 10%to 68%, and the comprehensive treatment facilities reached 7 categories.

Among them, the renewable energy utilization center (phase and second phase) project enables the old port base to have the world's largest domestic waste incineration facility (the second phase of the second phase is the world's largest, up to 6,000 tons/day; The world's largest, up to 9,000 tons/day), can be incinerated to deal with 3 million tons of domestic waste each year. The efficient thermal energy recovery system enables the entire plant to reach 26%, and the power generation can reach nearly 600 kWh/ton garbage. It can transport nearly 1.5 billion kWh of clean power to the outside world each year, becoming a model for garbage resource and energy recycling.

Through the construction of biological energy reuse projects (Phase I and 2), filling the "blank" field of wet garbage disposal and making up for the lack of disposal capacity is the affordable facilities that realize the classification of Shanghai's domestic waste. It is also a municipal major livelihood project. The scale of the first and second phases is 2500 tons/day. The project operation adopts the "pre -processing+dry, wet anaerobic and digestive collaborative treatment" processing process, and the annual power generation is exceeded 20 million degrees. While efficiently deal with wet garbage Cycle economic concept.

In 2020, Shanghai City Investment became the main body of the unified management of the old port base. On December 11th, the "Shanghai City Investment Old Port Base Management Co., Ltd." was listed on December 11 to promote the realization of "unified planning, unified development and construction, unified operation dispatch, and dispatching. Unified management service. Immediately afterwards, Shanghai City Investment launched the "Three Championship Battle" in the old port base: the first game was odor governance, and the goal was to basically solve the problem of odor and disturbing the people at the end of 2021; The "zero landfill" of garbage; the third game is to continue to eliminate inferior V water in the base. These are also the weakest issues of public infrastructure in the old port base.

In terms of odor governance, the old port base should strengthen the coverage of domestic garbage dumps in accordance with the principle of receiving gas receivables; Devuling facilities. In 2021, the number of odor alarms decreased by 57%year -on -year, and the number of complaints decreased by 80%year -on -year. The effect of the odor control of the base was basically controlled. After the "zero landfill", the effect of odor governance was further improved. So far, it has exceeded the standard.

On the "zero landfill" of native domestic garbage, the old port base has strengthened the construction of the end -of -end disposal facilities. On the basis of the original 9,000 tons/day domestic waste incineration, 1,000 tons/day wet waste resource disposal facilities, accelerate the advancement of 1,500 tons/day The construction of the second phase of wet garbage; strengthen the maintenance and coordinating facility, and strengthen the operation scheduling. On November 21, 2021, the "zero landfill" of native domestic waste was successfully achieved.

In terms of water environmental governance, the 6 planning and preservation of river channels and other small and micro water bodies in the base monitor water quality. Medium -term planning and rectification plan. As of now, the "Three Battle" has achieved a staged victory, and the old port base has shown the new management appearance of "wearing new shoes and taking a new road".
