Description
Technical Field
The invention relates to the field of livestock wastewater treatment, in particular to a method for treating wastewater in livestock breeding.
Background
The livestock breeding utilizes the physiological functions of animals such as livestock and poultry which are domesticated by human beings or wild animals such as deer, musk, fox, marten, otter and quail, and the plants such as pasture, feed and the like can be converted into animal energy through artificial breeding to obtain the production departments of livestock products such as meat, eggs, milk, wool, cashmere, skin, silk, medicinal materials and the like.
Firstly, the ODOR pollution is caused by harmful gases such as NH3, H2S, TVOC, ODOR and the like, the ODOR is harmful to the health of people and livestock, and ammonia and hydrogen sulfide in the breeding waste gas can stimulate the trachea, the lung and the eye conjunctiva of the pigs; after people breathe excessively, the people can cause dyspnea and destroy the hematopoietic function of the human body, and the serious consequences such as death of the human body and the like can be caused by a large amount of respiration; second, pathogen contamination, pathogenic microorganisms carried in aquaculture waste, can cause cross-contamination between animals. Not only influences the growth performance of the pigs, reduces the immunity of the pigs and induces diseases; thirdly, the waste water is polluted, and a large amount of food residues and excrement urine exist in the breeding waste water, so that the breeding waste water belongs to waste water which is difficult to treat.
The livestock breeding wastewater mainly comes from excrement, urine, residual feed, pathogenic bacteria, various flushing fluids in breeding places and the like in the breeding process of livestock. The treatment difficulty of the waste water generated under different breeding modes is different. Especially, compared with the liquid dung generated by other breeding modes, the water-soaked liquid dung breeding wastewater in the livestock breeding mode has higher treatment difficulty, has high CODcr, high ammonia nitrogen, high suspended matters, high phosphorus, high fiber, high protein, large chromaticity and the like, has smaller particle size of the suspended matters, is integrated with protein and other organic pollutants, is difficult to separate, and has great difficulty, large investment, high operating cost, large environmental protection pressure and difficult bearing of farmers.
Meanwhile, a large amount of organic matters in the livestock breeding wastewater are resources, and can be well recycled through some treatment modes.
At present, domestic deodorization of livestock breeding places is not treated or recycled in a real sense, and even if the treatment generally adopts a more traditional medicament spraying method for environmental protection acceptance inspection, the methods have the defects of large field construction amount, large investment and high operating cost.
Disclosure of Invention
The invention aims to provide a livestock breeding wastewater treatment method to solve the technical problems of imperfect livestock breeding wastewater treatment method, large field construction amount, large investment and high operation cost in the prior art.
A method for treating wastewater in animal husbandry industry comprises the following steps:
s1: arranging a drinking water storage tank outside the cultivation shed, adding enzyme bacteria into the water storage tank, and communicating the water storage tank to a water tank in the cultivation shed, wherein the enzyme bacteria are composed of digested and decomposed enzyme and 600 types of microorganisms secreting the decomposed enzyme;
s2, arranging a separation fence at the bottom of the cultivation shed, arranging a drainage layer below the separation fence, and enabling excrement of livestock to pass through a separation grid and fall into the drainage layer;
s3: arranging a flushing tank, arranging a water pump at the flushing tank, pumping water in the flushing tank into the drainage layer through the water pump, and flushing excrement in the drainage layer by using water in the flushing tank;
s4, arranging a wastewater collecting tank which is communicated to the drainage layer, and collecting wastewater in the drainage layer in a centralized manner through the wastewater collecting tank to prevent excrement from entering the outside to cause environmental pollution;
s5: the method is characterized in that a nanometer micro bubble machine is arranged, the oxygen content of the wastewater in the wastewater collecting tank is increased through the nanometer micro bubble machine, the odor generated by fermentation of excrement in water is prevented, 100% of oxygen is dissolved in the excrement by adopting a nanometer dissolved oxygen technology, and NH3-N is hardly generated in the excrement;
s6, arranging an instant reaction tank communicated to a waste water collecting tank, and arranging an anaerobic reactor and special microorganisms in the instant reaction tank;
s7, circularly sending the water source treated by the instant reaction tank into a nano micro bubble machine for treatment and recycling;
s8: the water source treated by the instant reaction tank can be added with different microorganisms according to different crops, and forms special bacterial manure for the circulation utilization of the farmers after aeration.
Further, be provided with the bacterium room in the water storage tank, can satisfy ferment fungus and breed in the water storage tank through the bacterium room that sets up.
Furthermore, the transient reaction tank consists of a reaction tower body, a plurality of baffle plates and a gas collecting cover, a wastewater inlet pipe is arranged at the bottom of the reaction tower body and communicated with a wastewater collecting tank, the baffle plates are provided with a plurality of baffle plates which are arranged in the reaction tower body, a purified water discharge pipe is arranged at the position close to the transient reaction tank and communicated with the flushing tank, the gas collecting cover is arranged at the top of the reaction tower body, and a gas collecting port is arranged on the gas collecting cover.
