Description

Electrolytic water disinfection system for livestock and poultry breeding
Technical Field
The invention relates to the field of livestock and poultry breeding, in particular to an electrolytic water disinfection system for livestock and poultry breeding.
Background
With the economic development and the technical progress, the livestock breeding industry in China is continuously and vigorously developed, however, with the continuous expansion of the livestock breeding scale, the problems of bacteria sterilization, air purification, wastewater treatment, drinking water treatment and the like in the livestock breeding are urgently solved.
A large amount of bacteria and viruses exist in livestock farms, so that livestock diseases are easily induced, and economic losses are caused. At present, more and more livestock farms begin to pay attention to the problem of bacterial breeding, however, in actual operation, farms mostly adopt manual spraying operation, and the adopted disinfection water is also manually prepared, so that the operation is very troublesome, the working efficiency is low, and the problems of easy generation of sanitary dead angles and large water consumption are solved. In addition, the current livestock farms do not systematically disinfect the entire plant area, vehicles and personnel, which also creates disease risks.
The livestock and poultry farm often has the condition that the content of ammonia nitrogen, hydrogen sulfide and other gases is too high, and at present, the farm is mostly ventilated by adopting a fan system, however, the waste gases are directly discharged into the atmosphere without treatment, so that the air pollution around the livestock and poultry farm is caused, and the ecological environment is destroyed. The current ventilation treatment method does not fundamentally solve the problem of air purification. Moreover, the air in the livestock and poultry farm can also contain bacteria and viruses, and the bacteria and viruses easily cause the health problem of livestock and poultry, and untreated air is discharged into the atmosphere, so that the viruses are easily diffused.
The wastewater of the livestock and poultry farm has the conditions of high concentration of organic matters, high COD value, high ammonia nitrogen content, high organic phosphorus content and high suspended matters, wherein the COD value is as high as 3000-12000mg/L, the ammonia nitrogen content is as high as 800-2200mg/L, and besides, the wastewater of the livestock and poultry farm also contains a large amount of bacteria, and if the wastewater is directly discharged, serious pollution is caused to the environment. At present, corresponding treatment technology is adopted for wastewater of farms, but bacteria and viruses in the water are not killed, and the obtained water still has the problem of bacteria exceeding standards.
The drinking water for livestock and poultry cultivation mainly takes well water, the management and disinfection of the well water are closely related to livestock and poultry, and the water quality extracted from a well into a water pool must be sterilized and disinfected. Because the well water is taken from the ground, the water source can be influenced by underground pollutants, earth surface dirt, rainfall and the like, and various bacteria viruses or microorganisms such as red worms, algae and the like are easy to breed. In order to prevent the occurrence and popularity of water-borne diseases and ensure the health of livestock and poultry, the livestock and poultry drinking water is disinfected by farms, however, more than 90% of farms in China adopt a conventional treatment process for the livestock and poultry drinking water, and the conventional treatment process can only remove about 30% of organic matters in water and has very limited treatment effect on some pollutants, especially chemical pollution.
Therefore, a system capable of simultaneously treating bacteria killing, air, wastewater and drinking water in livestock and poultry farming is an urgent need for farming.
