What is the water pollution situation in Chenghai?
Lianhuashan tungsten mine is located in the north of Hongyan Town, Chenghai District, Shantou City. It is an important tungsten mine in Guangdong in the last century. Due to the failure to take effective measures to control pollution after the closure of this tungsten mine, a large number of untreated toxic and harmful substances were left behind, which had a great impact on the production and life of more than 40,000 people in 9 nearby villages. So how serious is the impact of abandoned mining areas? Let's go and have a look.

This high hill without any vegetation is actually made of waste ore. It is understood that in the mining area of more than 4,000 mu in Lianhua Mountain, there are still many tailings piles piled up at will without any treatment. Whenever it rains, harmful substances will flow down with the rain, affecting and destroying the local ecological environment.

(Liu Wensheng, deputy mayor of Hongyan Town, Chenghai District: These wastewater are discharged to the banks of Chengrao, which affects the production of more than 5,000 mu of crops below us. )

(Solution) What is even more worrying is that due to the lack of strict planning, these waste ores are piled up on the mountain surface, with the highest accumulation area of180m and the longest slope angle line of 3,700m, all of which are above 30 degrees, which hides the danger of geological disasters.

(Liu Wensheng, deputy mayor of Hongyan Town, Chenghai District: The slope of these waste ores is 60-70 degrees, which is also easy to cause some geological disasters such as mudslides. )

(Solution) The reporter learned that after decades of mining, the mountains around Lianhuashan Tungsten Mine have been basically hollowed out, and 40 mines are all over the mining area.

(Wang Wenfeng, Director of Chenghai District Environmental Protection Bureau: These mines are not closed, which gives our local villagers the opportunity to mine. In addition, the tungsten mine has not been closed, which is not convenient for our ecological restoration and leads to a large loss of mine wastewater. )

(Solution) At present, the main hidden dangers in Lianhuashan mining area are not only the 16 unsealed mine, but also six sand yards used for ore washing for a long time. These six battlefields have a total area of over 300,000 square meters. Here, there are bare waste ore and waste ore sand everywhere, the pH of the soil has completely changed, and the surface water is red because of pollution. The reporter saw that although there is soil and water, there is almost no grass in this area.

(Wang Wenfeng, Director of Chenghai Environmental Protection Bureau: The waste water produced by tailings is acidic, and its PH value is relatively low ... It will change our water quality and affect the restoration of our whole ecology. )

(Solution) This is the drainage ditch where the Lianhuashan tungsten mine extends all the way to the seaside. Due to the toxic water pollution in the mining area for many years, the fertility of nearly 3000 mu of farmland on both sides of this drainage ditch has been seriously reduced, and some farmland has been abandoned.

(Lin Huanbin, a villager from Shangshe Village, Hong Yan Town, Chenghai District: Every time it rains heavily, this ditch overflows to both sides when it is full, and there are many farmland and fish ponds affected. )

(Solution) For this drainage ditch, the Chenghai District Government has allocated funds for special treatment in recent years, but the local villagers have reported that the treatment effect is not very satisfactory.

(Lin Huanbin: The effect of the first phase of remediation is still not enough ... The dikes are still relatively low, and the two sides (stone fences) are also relatively low, which can't meet the needs. )

In addition, the wastewater from the mining area also has a great impact on the local fishery and aquaculture. The aquaculture industry in Hongyan town is very famous, but according to the masses, some local ponds have been polluted, so it is no longer possible to cultivate high-value aquatic products. Lin Huanbin, a villager, told reporters that his younger brother rented land from the village a few years ago to raise crabs, but later he lost money because a large number of crab seedlings died.

(Moderator) The ecological pollution caused by the Lianhuashan tungsten mine involves the production and living problems of more than 40,000 people in 9 villages. Therefore, the local people very much hope to get the support of the higher authorities, come up with more effective and thorough pollution control plans as soon as possible and put them into practice, so that they can have a good production and living environment again. In Chaoan County, not far from Shantou Chenghai, a Taiwan Province man named Jiang Kundi came a few years ago. He didn't come to set up a factory or do business. He rented nearly 10 acres of land. what does he want to do?
