为了解河南省沙颍河流域畜禽养殖业对环境的污染状况,在流域内平顶山、漯河、许昌、郑州、周口5市所辖区域选择猪、鸡、牛的典型养殖场,分季节采集污水和粪尿,进行化学需氧量(COD)、氨氮(NH3 N)含量检测,计算排污系数,结合各市耕地面积,估算畜禽粪便耕地负荷,采用畜禽粪便负荷警报分级方法评价畜禽养殖环境污染状况。结果表明:沙颍河流域内畜禽养殖量占河南省畜禽养殖总量的25·19%,畜禽个体排污系数以牛最大,其次是猪、鸡,流域内年产生畜禽污染物总量为7529·414万 t,各市畜禽污染物产生量大小依次为:周口、平顶山、许昌、郑州、漯河;流域内单位耕地面积平均畜禽粪便负荷为33·07 t/hm2,NH3 N 耕地负荷为43·47 kg/hm2;畜禽粪便负荷警报值在0·51~1·19,警报值级别为Ⅱ~Ⅳ级,其中以平顶山最为严重。说明河南省沙颍河流域内5市的畜禽养殖污染物已经对环境构成了不同程度的污染。
為瞭解河南省沙潁河流域畜禽養殖業對環境的汙染狀況,在流域內平頂山、漯河、許昌、鄭州、週口5市所轄區域選擇豬、鷄、牛的典型養殖場,分季節採集汙水和糞尿,進行化學需氧量(COD)、氨氮(NH3 N)含量檢測,計算排汙繫數,結閤各市耕地麵積,估算畜禽糞便耕地負荷,採用畜禽糞便負荷警報分級方法評價畜禽養殖環境汙染狀況。結果錶明:沙潁河流域內畜禽養殖量佔河南省畜禽養殖總量的25·19%,畜禽箇體排汙繫數以牛最大,其次是豬、鷄,流域內年產生畜禽汙染物總量為7529·414萬 t,各市畜禽汙染物產生量大小依次為:週口、平頂山、許昌、鄭州、漯河;流域內單位耕地麵積平均畜禽糞便負荷為33·07 t/hm2,NH3 N 耕地負荷為43·47 kg/hm2;畜禽糞便負荷警報值在0·51~1·19,警報值級彆為Ⅱ~Ⅳ級,其中以平頂山最為嚴重。說明河南省沙潁河流域內5市的畜禽養殖汙染物已經對環境構成瞭不同程度的汙染。

In order to investigate the pollution status of livestock industry in Shaying river basin which is located in Henan province,the research selected typical livestock farms in Pingdingshan, Luohe,Xuchang,Zhengzhou and Zhoukou within the basin.Waste water and feces were collected seasonally.The COD and ammoniacal nitrogen content were detected,so that the discharge coefficient could be calculated.Combing with the scale of livestock and arable area of the cities, the amount of livestock excrementsand farmland pollution load were calculated.Then the pollution status of livestock and poultry breeding industry of existing scale was evaluated according to feces load alarm classification method.Combined with the local effective cultivated area of Henan statistical yearbook,the pre-warning value was used to evaluate the assessment for pollution situation of livestock industry.The results showed that the amounts of livestock industry withinShaying river basin made up 25·19% of all in Henan.The discharge coefficient of cattle is the largest,followed by pig and chicken.There were 75·294 14 million tons livestock manure from breeding per year.Zhoukou tops the list of pollutants production of five cities, followed by Pingdingshan,Xuchang,Luohe and Zhengzhou.The average waste loading of livestock withinthe basin was 33·07 t/ha;The average ammoniacal nitrogen loading was 43·47 kg/ha. The pre-warning value of livestock manure load in five cities were 0·51 - 1·19 respectively,while the alert level of them wereⅡ-Ⅳ.In conclusion,the environment ofShaying basin has been polluted in varying degrees.
