In order to effectively improve the ecological environment of mines and realize the virtuous circle of mine resource development and ecological environment protection, Huzhou City carried out special environmental renovation work for mining enterprises in 2009. More than a year later, what changes have taken place in more than 200 mining enterprises in Huzhou City through renovation? From today on, we will launch a series of reports, "Looking back on mine renovation", and follow our reporters to visit some mining enterprises. I believe it will certainly change your view of traditional mining enterprises.

Reporter Hu Leilei: You can see that the pool beside me is very clear, and trees are planted beside me. You may think that I am in the park. In fact, I am in the sedimentation tank of Jinfeng Mining Co., Ltd. This tank uses the addition technology of biological agents to make the originally turbid water clear and beautify the surrounding environment.

Previously, some mining enterprises in Huzhou City operated in an extensive manner, focusing on benefits and ignoring protection. In particular, a large amount of slag and mud in the production process were directly discharged into the river without treatment by water flushing technology, which accelerated the destruction of surface vegetation and soil erosion. Through mine renovation, many mines have used biological agents to turn the original sewage into treasure. Deli Mining Co., Ltd., which is separated from Jinfeng Mining, is also one of the mining enterprises that used biological agents earlier.

Zhang Jinjiang, assistant to the president of Huzhou Deli Mining Co., Ltd, After the density is increased, it will sink naturally. After the sewage is dehydrated, the mud will be dried and put on the site. This mud can be used for houses, ponds and other places.

Through a variety of measures, the silt in the sewage is gradually separated from coarse to fine, and the tailings are recovered at multiple levels. The wastewater has been effectively treated, reaching the treatment goal, and ensuring the recycling of production wastewater.

Zhang Jinjiang, Assistant to the Chairman of the Board of Directors of Huzhou Deli Mining Co., Ltd.: Through three processes of treatment, all the wastewater produced by our company has been recycled, which not only solves the pollution problem of production wastewater, but also reduces the production cost.

The mine renovation work focuses on three aspects: dust noise, sewage treatment and waste disposal. Deli Mining Co., Ltd. has carried out renovation one by one within half a year.

Zhang Jinjiang, Assistant to the Chairman of the Board of Directors of Huzhou Deli Mining Co., Ltd.: In recent years, we have spent more than 8 million yuan on environmental investment. We have also created a provincial green mine. Now we plant more than 20000 square meters of trees.

The quality of mine environment renovation is related to the image of mining enterprises and the development of enterprises themselves. Through mine renovation, not only the ecological environment of the mining area has been greatly improved, but also the construction of Huzhou Ecological City has been promoted.
