It promotes.Therefore, under existence conditions, if cannot thoroughly solve the problems, such as that biogas converts, inherently a kind of environment of biogas
Pollution to soil is only become the pollution to air by pollution sources, this is apparently not what country was encouraged.Therefore, biogas
It is difficult that fermentation is promoted for large-scale cultivation.
(2) in compost utilization mode, although aerobic compost is smaller than anaerobic composting pollution, but still it will cause the biography of foul smell
It broadcasts, causes air pollution；Meanwhile compost will cause the growth of fly maggot, a large amount of bacteriums can be such that the pollution of culture zone increases, influence to raise
The healthy growth of fowl, the main reason for a certain extent and livestock and poultry being caused to die of illness.
(3) defect of oxidation pond process is that oxidization time is long, it is desirable that sufficiently large oxidation pond area.In autoxidation process, greatly
The indexs such as enterobacteria, roundworm egg are extremely difficult to the absorption standard in soil, will cause soil pollution.In addition, the oxidation pond of large area
Caused by foul smell, fly the problems such as, be easy surrounding air is polluted.
(4) self-built sewage disposal system in farm is reached sewage treatment at COD and VOD by medicament or microorganism
Mark discharge；Although such mode can administer, invests huge, operation technology and higher cost, most farms are difficult to
It bears.
To sum up, scale livestock farming problems faced, first is that daily stink and fly maggot bring environmental issue, especially in the summer
Season, farm stink to high heaven, and fly in groups, is easy to cause the environmental pollution of surrounding area, it is difficult to pass through the inspection of environmental protection administration；
Second is that environmental issue caused by organic matter and harmful organism, if the organic matter in waste is directly applied without microbial fermentation
Soil is easy to happen secondary fermentation and leads to burn root, meanwhile, harmful microorganism enters soil and is easier to cause land pollution.Separately
Outside, the agriculture and forestry organic waste material generated every year is at will burned without centralized processing, also results in serious environmental pollution.
