Groundwater pollution incident of Shandong Xinfa Aluminum Group Co., Ltd.

Leaving chiping County, along the 309 National Road to the west, almost all enterprises under Xinfa Group are within 5 kilometers. Along the way, there are many chimneys and high-voltage lines, all kinds of large-scale smelting equipment roar everywhere, and enterprises such as electrolytic aluminum, alumina, power generation and heating line up for several kilometers. Coming here is like entering a large industrial zone. According to the taxi driver, the factory next to National Highway 309 is only one-fifth of Xinfa Group's main factory in chiping.

In the southeast corner of Han Gan Village, the original 500 mu of land in the village was requisitioned by Xinfa Group at a price of 40,000 yuan per mu as a storage yard for red mud treatment. After aluminum powder is used to extract alumina, it will produce waste water such as waste residue and red mud. These large pits covering an area of more than 500 mu are used to precipitate red mud.

For the red mud produced in aluminum industry, it is generally necessary to carry out anti-seepage treatment to prevent the red mud leaching solution from entering the groundwater system. According to reports, once the red mud wastewater enters the underground water system, it will increase the pH value of the water body and affect the toxicity of the compounds in the water. Fluoride, aluminum and other substances contained in red mud will also cause more serious water pollution. People's long-term intake of these substances will affect their health. 20 10 5438+00 June, the red mud pile of an alumina factory in Hungary burst its bank, and the red mud wastewater flowed into the Danube, causing panic in many European countries.

Red mud water is very toxic, and crops are basically dead wherever it flows. The local villagers said, and now they don't drink groundwater.
