Pollution Status and Measures of Environmental Management of Large-scale Livestock and Poultry Farms in Chaohu River Basin

[Objective] The research aimed to investigate the status and pollution situation of livestock and poultry breeding industry in Chaohu river basin,and put forward the corresponding measures.[Method] Based on investigating the statistical data of Chaohu Animal Husbandry Bureau and pollution status of part breeding districts,the pollution status of large-scale livestock and poultry breeding industry in Chaohu river basin was analyzed and the corresponding environmental management and control measures were proposed.[Result] Currently the quantity of various pollutants produced by large-scale livestock and poultry breeding industry in Chaohu river basin was large.When the feces of all kinds of livestock and poultry investigated in Chaohu river basin were converted to the equated pig excrement,according to the day excretion of livestock and poultry,it was calculated that the annual quantity of total feces from livestock and poultry in Chaohu river basin was 25.153 5 million t,BOD was 1.024 6 million t,COD was 856.4 thousand t,the produced ammonia nitrogen was up to 117 000 t.The number of large-scale breeding farms of Chaohu river basin was comparatively larger(Juchao area was 133),many breeding species,too scattered,quite small in scale(taking pigs for example,the average number was 176).[Conclusion] Aiming at the pollution problems in livestock and poultry breeding farms in this river basin,some measures of environmental management suitable to large-scale livestock and poultry breeding industry in Chaohu river basin were proposed.
