Description

Water electrolysis 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 breeding industry in China is continuously developed vigorously, however, with the continuous expansion of the breeding scale of livestock and poultry, the problems of bacterial killing, air purification, wastewater treatment, drinking water treatment and the like in the breeding of livestock and poultry need to be solved urgently.

A large amount of bacteria and viruses existing in livestock and poultry farms are easy to induce livestock and poultry diseases, and further cause economic loss. At present, more and more livestock and poultry farms begin to attach importance to the problem of breeding of bacteria, however in actual operation, the farm adopts the operation of manual spraying more, and the disinfectant fluid of adoption is also manual preparation, and such operation is very troublesome, work efficiency is low, has the problem that produces sanitary dead angle easily, and the water consumption is big. In addition, the current livestock and poultry farms do not systematically sterilize the entire plant area, vehicles and personnel, which also creates a risk of disease.

Often have the too high condition of gas content such as ammonia nitrogen, hydrogen sulfide in the beasts and birds plant, present plant adopts fan system more, does the ventilation treatment to the plant, however these waste gases are all directly to discharge among the atmosphere untreated, have resulted in the peripheral air pollution of beasts and birds plant, have destroyed ecological environment. The current ventilation treatment method does not fundamentally solve the problem of air purification. Moreover, the air in livestock and poultry farms may also carry bacteria and viruses, which easily cause health problems of livestock and poultry, and are discharged into the atmosphere without being treated, thus easily causing the diffusion of viruses.

The wastewater of the livestock and poultry farm has the conditions of high organic matter concentration, high COD value, high ammonia nitrogen content, high organic phosphorus content and many suspended matters, wherein the COD value is as high as 3000-plus 12000mg/L, the ammonia nitrogen content is as high as 800-plus 2200mg/L, and moreover, the wastewater of the livestock and poultry farm also contains a large amount of bacteria, and if the wastewater is directly discharged, the environment can be seriously polluted. At present, corresponding treatment technologies are provided for wastewater of a farm, but bacteria and viruses in the water are not killed, and the obtained water still has the problem that the bacteria exceed the standard.

The drinking water for livestock and poultry breeding mainly takes well water as main water, the management and disinfection of the well water are closely related to livestock and poultry, and the water quality extracted from a water well into a water pool needs to be sterilized and disinfected. Because well water is taken from underground, water sources can be influenced by underground pollutants, surface dirt, rainfall and the like, and various bacteria and viruses or microorganisms such as red worms, algae and the like are easy to breed. In order to prevent diseases transmitted by water from occurring and spreading, ensure the health of livestock and poultry, the livestock and poultry farms disinfect drinking water, however, more than 90% of livestock and poultry drinking water in China still adopt a conventional treatment process, the conventional treatment process can only remove about 30% of organic matters in the water, and the treatment effect on some pollutants, especially chemical pollution, is very limited.

Therefore, a system capable of simultaneously treating bacterial killing, air, wastewater and drinking water in livestock and poultry breeding is an urgent need for breeding.
