Is the pollution from the copper smelting plant particularly serious? What kind of pollution is there?

Qingyuan Daily (reporter Zhuo Xiaochou, correspondent Tong Weijuan) held the verdict of "sentenced to one year and six months in prison and fined RMB 20,000". Farmer Cai Mou issued: "I regret it." Shouldn't have done it in the first place!" he sighed. Cai wanted to get rich, but he only cared about immediate interests and ignored future generations. He chose to use local methods to smelt copper and sell it for money. In the end, he made a big fuss and made no money. Instead, he was sent to prison. Cai's indigenous copper smelting caused serious pollution to the soil environment

It is understood that at present, Qingyuan's recycled copper industry is mainly distributed in Shijiao and Longtang towns, with tens of thousands of people engaged in this industry. In June 2008, Cai also joined this mighty copper smelting army. Compared with those veterans who have been in this industry since the 1980s and 1990s, the 31-year-old Cai is only a newcomer. But his "movement" was quite big. He first rented an abandoned factory with an area of ??about 600 square meters in a village in Longtang Town, dug two large ponds and two small ponds, and purchased some necessary equipment. In this way, a simple but decent copper sulfate factory was established.

Buy industrial copper sulfate water from outside, and then use iron to chemically react with it to replace the copper inside. Cai used this simple method to start his own "road to wealth." "During the replacement process, you will smell a sour smell and there will be a layer of water mist on the water surface." Cai described the process of copper smelting. The wastewater generated after refining is directly discharged outside without any harmless treatment. According to statistics, from June 2008 until he was banned in February this year, Mr. Cai purchased more than 1,000 tons of copper sulfate water. After testing, the copper content in the soil of the copper sulfate plant was 465.145-10140.913mg/kg, seriously exceeding the "Soil Environmental Quality Standard" (GB15618-1995) soil control level three standard ≤ 400mg/kg by 0.16 to 24.35 times. Copper seriously exceeds the standard and has caused serious pollution to the soil environment.
