Description

A breeding wastewater disinfection treatment device

technical field

The utility model relates to a waste water treatment device, in particular to a breeding waste water disinfection treatment device.

Background technique

The livestock and poultry industry is an important part of my country's agriculture and rural economy. The environmental pollution caused by the vigorous development of the livestock and poultry industry is becoming more and more serious. The emissions of major pollutants from domestic, domestic and industrial sources were analyzed and summarized. Among the agricultural sources, the COD and ammonia nitrogen emissions from the livestock and poultry breeding industry were 12.6826 million tons and 717,300 tons respectively, accounting for 95.8% and 78.1% of the agricultural source COD and ammonia nitrogen emissions, accounting for 41.9% of the national COD and ammonia nitrogen emissions and 41.5%.

At present, the amount of livestock and poultry breeding wastewater discharged by large-scale farms across the country is large and concentrated every day, and the wastewater contains a large number of pollutants, such as CODcr, ammonia nitrogen, heavy metals, residual veterinary drugs, and a large number of pathogens. If it is discharged directly without treatment, it will be It will cause serious pollution, and its main hazards are as follows: aquaculture wastewater is a high-concentration organic wastewater containing a large number of pathogens. After a large amount of organic matter enters the water body, the decomposition of the organic matter will consume a large amount of dissolved oxygen in the water, making the water body smelly, and causing aquatic organisms A large number of deaths; nitrogen and phosphorus can make water eutrophication; livestock and poultry breeding wastewater will produce a large amount of NH3, H2S and other odorous gases under anaerobic conditions, and these odorous gases will affect and endanger the health of breeders and surrounding residents; Poultry farming wastewater contains more nutrients such as nitrogen, phosphorus, and potassium. If it is applied directly, continuously, and excessively without any treatment, it will have adverse effects on the growth of soil and crops, such as causing crop yields to decrease. Delay the maturity period and affect the production of subsequent crops.

At present, wastewater treatment technologies mainly include: wastewater pretreatment technology and wastewater comprehensive treatment technology. No matter what comprehensive measures are used to treat wastewater from livestock and poultry farms, solid-liquid separation must be carried out first. At present, my country has mature solid-liquid separation technology and corresponding equipment. The types of equipment mainly include screen type, horizontal centrifuge, filter press, etc.; livestock and poultry wastewater generally requires a combination of multiple treatment technologies. From the perspective of treatment technology, in order to achieve the effect of removing CODcr and BOD5 while removing nitrogen and phosphorus, anaerobic process is indispensable. At present, there are mainly two modes for the treatment of livestock and poultry breeding wastewater in my country: one is the anaerobic-natural treatment mode, which is suitable for small and medium-sized large-scale farms; the other is the anaerobic-aerobic utilization mode, which is suitable for large and medium-sized livestock Poultry farms or breeding areas.

Anaerobic + natural treatment technology is characterized by low cost, less land occupation, low energy demand, and can generate biogas; moreover, the treatment process does not require oxygen and is not limited by the oxygen transfer capacity, so it has a high potential for organic matter loading and can make The parts that cannot be degraded by some aerobic microorganisms are degraded. Common anaerobic methods include fully mixed anaerobic digester, anaerobic contact reactor, anaerobic baffle reactor, upflow anaerobic sludge bed, anaerobic fluidized bed, upflow solid reactor, etc.

The natural treatment method is to use the physical, chemical and biological comprehensive effects of natural water, soil and organisms to purify sewage. This type of method has low investment, simple process and low power consumption, but the purification function is restricted by natural conditions. The main modes of natural treatment are oxidation pond, soil treatment method, artificial wetland treatment method and so on.

Anaerobic + aerobic treatment technology: The basic principle of aerobic treatment is to use microorganisms to decompose organic matter under aerobic conditions and synthesize their own cells at the same time. In aerobic treatment, biodegradable organics are finally fully oxidized to simple inorganics. The methods mainly include activated sludge method, biological contact oxidation, SBR, A/O and oxidation ditch.

As a national key pollution prevention and control industry, the livestock and poultry breeding industry has attracted more and more attention to the standard treatment of its wastewater. The livestock and poultry breeding wastewater has typical "three highs" characteristics, high CODcr, high ammonia nitrogen, and high SS. Currently, a single treatment method cannot Meet the requirements of wastewater discharge standards. Therefore, it is necessary to combine the different species of farms and the different methods of cleaning manure, and adopt a combined treatment method according to the water quantity and water quality, and comprehensively consider the investment of the treatment method, daily operating costs and whether the operation is convenient.

In order to do a good job in the prevention and control of pollution in the livestock and poultry breeding industry, reduce the discharge of waste water and the input of chemical substances to the environment, and minimize the pollution, it is necessary not only to realize the harmlessness of the treatment process, but also to realize the resource utilization of the treatment process, effectively In order to protect and improve the rural ecological environment and promote the sustainable and coordinated development of the livestock and poultry breeding environment and the economy, we need to provide a fast-processing, low-cost, and easy-to-operate aquaculture wastewater disinfection treatment device, which can convert wastewater pretreatment technology and wastewater Partially treated wastewater treated by comprehensive treatment technology is accelerated to make it meet the standards of farmland water use, and solve the shortcomings of traditional aquaculture sewage treatment methods, such as high cost and slow treatment speed.
