采取现场调查和排污系数推算相结合的方法。研究区域内规模养牛粪便和污物的区域分布、污染类型、产生量、排放量及其综合利用情况。表明：区域内牛粪尿年排放总量100.85×104 t,其中：规模养牛粪尿年排放总量29.47×104 t,养牛小区、场和大户各占21.41%、24.49%和54.10%。COD 年排放668.07×104 kg,BOD 年排放432.72×104 kg, NH 3-N 年排放总量为67.79×104 kg,N 年排放量在为65.01×104 kg,P 年排放量为27.50×104 kg。粪便负荷量7.83 t/hm2,占总负荷量21.53 t/hm2的36.37%。年流失量2.38×104 t,占8.08%。进行臭源监测和臭气评价,牛舍内 H 2 S 0.15 mg/m3,NH 32.77 mg/m3。综合利用率91.92%。

To study a certain area raising cattle in a large scale from some aspects,such as faeces,re-gional distribution of dirt,the pollution type,output,emissions and comprehensive utilization.the adopt the method of field investigations combining with calculation of pollution discharging coefficient was car-ried out.The results showed that the total annual emissions of excreta was 100.85×10 4 t in intra-area, and the total annual emissions of excreta was 29.47 ×10 4 t in the area which raise cattle in a large scale. The cattle raised village,field and large field each accounted for 21.41%,24.49% and 24.49%,respec-tively.Moreover,the annual emissions of COD was 668.07×104kg,and the annual emissions of BOD was 432.72×10 4 kg.The annual emissions of NH3 was 67.79×10 4 kg,and the annual emissions of N was 65. 01×10 4 kg.The annual emissions of P was 27.50×10 4 kg.The payload of faeces was 7.83 t/hm2 ,and it took 36.37% of the total load which was 21.53 t/hm2 .The loss amount of every year was 2.38×10 4 ,tak-ing 8.08% of the total amount.There was H 2 S (0.15 mg/m3 )and NH 3 (2.77 mg/m3 )in cattle stall;the rate of multipurpose utilization was 91.92%.
