The only one for first -class and strive for the first time ｜ Coal mining collapse into the pearl "cornucopia"

Editor's note: Keep in mind that the instructions are entrusted to the front, and the mission will start a new game. From August to September, Jining Radio and Television launched the "Walking in front of the new bureau, striving for first-class and striving for the first-in-one-the 20th National Congress of the Party" Jining 14 counties and urban areas of the city. The forms of experience, marching reports, and panoramic display, etc., fully demonstrate the positive progress and achievements of counties and cities in the implementation of the "Nine Congress Strategy" in various counties and cities.

Jining News Network, August 26 (Correspondent Sheng Chao) In recent years, Zoucheng has seriously implemented the development concept of "green water and green mountains is the golden mountains and silver mountains", and take the ecological governance of coal mining and collapse as an important starting point for promoting high -quality development It has taken out a governance approach that takes into account ecology and economic benefits.

Walking in the coal mining area of ​​Taiping Town, Zoucheng, the green trees and the vertical and horizontal areas, the modern pearl breeding base of the Yanjin Qinghu Ecological Technology Co., Ltd. is located here.

"The pearls we have cultivated here are good. One of the volume and gloss can be sold for one or two thousand yuan. Essence

According to him, the stinky water flowing and grassy grass in this collapse area. In 2013, Zoucheng started the ecological restoration of the collapsed waters. At first, it was simply to simply fill the area with shallow water and fill in reclaiming into cultivated land.

"But this repair method not only has low economic benefits, but also a large amount of bait also makes the water body a trend of rich nutritionalization." Zhang Hao, a member of the Ecological Repair Section of the Natural Resources and Planning Bureau of Zoucheng, said that in order to solve this problem, this problem They all explored and inquired, and eventually finalized the ecological governance model of "biological chain and water -targeted pearl breeding".

Felinjiang said that before coming to Zoucheng, they had accumulated a lot of experience in the use of breeding river mussels for water governance in Hangzhou, Shaoxing, Zhuji and other places in Zhejiang. "River mussels have no hibernation, which is a kind of water -filtering and environmentally friendly animals. In the temperature season, a 3 -year -old river mussel can filter 50 liters of water a day. Taking 100,000 mussels as an example, the water filtering capacity can be treated with 200 cubic meters per hour. Water body. "Speaking of Xingtou, Fei Linjiang started a" popular science lecturer ". River mussel is a 'living body pure water manufacturing machine', which drinks dirty water but pure water. "

It is understood that the so -called biological chain water is to first draw the black and odorous water at the bottom of the pool to the Fan algae pond, and then transform organic matter into the inorganic salt that can be absorbed by the algae through microbio technology, and then cultivate algae suitable for feeding pearl mussels. The prominent feature of this technology is that in the process of water governance, no chemical reagents are added. Through intelligent feeding systems, according to water quality indicators, a stable pure ecological food chain system is established in the water body to achieve the purpose of ecological governance.

Felinjiang said that they adopt the automatic pipe network format breeding technology, drilled the hole in the appropriate position of the mussel shell and inserted into the dropper. Through a similar "Drop Drop", the algae were precisely transported to the magic mussels. The advantages of the particles filter the pond water body, thereby improving the water quality.

Now, through precise targeting feeding, automated suspension farming, fish and shrimp and shells, the bad catch of the fishery and lack of fish, on the basis of avoiding traditional breeding and sub -pollution. The left and right time can purify the inferior V water to the III class and maintain it for a long time. The clear water clearing and the "pearl and the treasure" truly realize the perfect combination, which fully meets the water quality requirements of fish, shrimp and shellfish, and the economy, ecology, and social benefits are significant.

Speaking of future development, Fei Linjiang said that they will develop biological chain water and targeted pearl breeding into the two major industries that serve local economic and social development, and develop to modern agricultural industrial parks integrated into the industry, research, research, and cultural tourism. It is understood that the project has already hung more than 1 million rivers and mussels. After all put into production, the annual production of 5,000 kg of freshwater pearls and an output value exceeds 10 million yuan. In the accelerated layout, the former collapse of the land has become a "cornucopia" for local development. This governance model has also been successfully selected into the typical case of ecological products of the Ministry of Natural Resources.
