Haiyan County, which is China's standard industrial base, has more than 1,200 fastener manufacturers in the county, and there are more than 120 acid-washing phosphating companies that specialize in derusting. There are five formerly located in Zhenxing Industrial Park. Since the water discharged by such enterprises still contains a certain amount of iron ions after processing, the water is rendered boring yellow, and there is no corresponding sewage pipe network in the industrial park, causing serious pollution of nearby rivers, Baiyang River It became the "Yellow River" and caused many troubles for nearby residents.

Zhang Da, head of the Haiyan County Environmental Protection Bureau Supervision Team, explained to the inspectors volunteers that the Haiyan County Environmental Protection Agency attached great importance to this and looked for the source of pollution. From the end of 2006 to the beginning of 2007, all enterprises in the region were discharged into the sewage pipe network. At the same time, inspections and law enforcement have been stepped up and penalties have been imposed on companies that illegally discharge pollutants. Enterprises have established discharge basins under the guidance of the County Environmental Protection Bureau, and the production wastewater is discharged regularly through open pipes. Pang Xiaofeng led the villagers to dredge in the river, and the Baiyang River finally cleared up again.

However, the “genuine murderer” is still hidden behind. After less than a month of happyness in the Mingzhu Village and County Environmental Protection Bureau, the Baiyang River has once again become “the flood of the Yellow River” and everyone is dumbfounded.

Environmental protection volunteers suggest that as a large taxpayer in Yuxin Town for many years, whether the company can use part of the funds for environmental protection projects can be used to take responsibility for the life of the people. In view of the current situation that industrial areas and living areas are too close to each other, environmental protection volunteers are suggesting that they can recommend to the Nanhu District Government to remove enterprises from the residential communities. This will also facilitate the centralized treatment of waste water and waste gas generated by the enterprises.

In December last year, in the strong voice of the masses and the media, the environmental protection department investigated and punished some local companies that had been polluted, stopped production and rectification of the five enterprises that violated the regulations and required them to further improve the wastewater and waste gas pollution control facilities. After transformation, the five companies have started trial production in February this year through the approval of the District Environmental Protection Bureau and Yuxin Town Government.

The environmental protection volunteers inspected an electroplating company in the trial production, seriously inquired about the entire production process, and the acid mist and wastewater treatment in the process. They also examined the sewage treatment pumping stations jointly invested by local companies. The leader of the supervision team of Nanhu District Environmental Protection Bureau, Jin Da, said that the responsible person of the company has greatly improved his awareness of environmental protection under the publicity education and punishment of the environmental protection department of the district. He actively shut down his own pollution comparison in the inspection at the end of last year. Serious production line.
