Large scale aquaculture hides' pollution 'and absorbs' dirt': How to 'break through the situation' from underground river pollution to odor disturbance to residents?

In recent years, the ecological environment problems of large-scale livestock and poultry farms have become increasingly prominent. The environmental pollution complaints against breeding enterprises or regions in many places are concentrated in several aspects: livestock and poultry manure polluting water bodies, producing serious odors, and illegal disposal of waste packaging materials such as feed and antibiotics. For example, the media once exposed the natural karst cave in Cili County, Zhangjiajie City, Hunan Province, which was dumped with garbage and the underground river was polluted. The main culprits were three nearby livestock and poultry breeding enterprises.

Improper management of large-scale livestock and poultry farms can easily lead to pollution. These types of farms generate a large amount of manure daily and commonly use water flushing cleaning, resulting in a significant increase in the amount of manure. Fecal treatment not only has high costs, but also requires stable treatment capacity and continuous investment, which poses significant pressure on enterprises.

On June 11th, the cleaning site of Datiankeng Cave in Caiqiu Village, Dongyueguan Town, Cili County.
Some breeding farms are driven by profit and resort to "crooked thinking": they may operate abnormally or even stop using sewage treatment facilities, waiting for opportunities to secretly discharge or illegally discharge manure into rivers, underground or seepage pits; Moreover, there are no substantial sewage treatment facilities built at all, and only "decorations" are set up to deceive people. In this regard, it is necessary to strengthen full chain supervision and build a solid defense line from source approval to daily supervision.
Although large-scale livestock and poultry farms are often built in remote areas far from villages, the large amount of livestock and poultry in the pens and the accumulation of manure can easily produce strong odors if not disposed of in a timely manner. Especially in summer, high temperatures accelerate fermentation, causing odors to spread with the wind and mosquitoes and flies to breed, seriously affecting the lives of surrounding residents. This is also the main reason for frequent complaints about such breeding farms. Governments at all levels, especially local governments in breeding counties (townships), need to prioritize the prevention and control of breeding pollution and plan systematic solutions in advance.

In the approval process, the ability to treat manure must be taken as the core standard for the approval of large-scale livestock and poultry farms: the proposed farm must have a complete and feasible manure disposal plan, otherwise it will not be approved; At the same time, strict control will be exercised over site selection, and no permits will be granted to ecologically sensitive areas, areas too close to village sites, or areas upwind of residential areas.

At the management level, it is necessary to strengthen the promotion of legal knowledge and policy guidance for breeding farms, enhance corporate social responsibility, and safeguard the legitimate rights and interests of surrounding residents. Guide breeding farms to establish and improve a full cycle pollution prevention and control system based on industry characteristics, equipped with efficient and reliable manure treatment and transportation facilities, to ensure standard emissions and reduce odors; At the same time, we will promote the upgrading and renovation of facilities, use advanced technology to turn waste into treasure, and promote the recycling of manure. In addition, it is necessary to establish a mechanism for self inspection of pollution risks, proactive reporting, and irregular visits to surrounding residents. Once pollution or disturbance problems are discovered, they must be highly valued, quickly investigated, and rectified to eliminate hidden dangers.

In terms of supervision, regulatory authorities should make the disposal of feces a key focus of supervision, use unmanned aerial vehicle inspections and other means to carry out regular monitoring, and hold accountable those who illegally dispose of feces. At the same time, fully leverage the role of the people around the breeding farm as a "supervisory outpost", timely verify and thoroughly investigate the clues reported by the masses, draw lessons from the verified problems, and fill in the gaps, forming a regulatory loop.
