摘要
本文对奶牛场废水处理工艺进行了研究。结果表明，奶牛场废水经混凝处理后，ＣＯＤｃｒ 从２０１０ ｍｇ／Ｌ 下降到５６３ｍｇ／Ｌ～６９１ ｍｇ／Ｌ，ＮＨ３ － Ｎ 可从７１ ｍｇ／Ｌ 下降到２５ ｍｇ／Ｌ～３３ ｍｇ／Ｌ，ＣＭ 从１８０ 度下降到４０ 度～７０ 度。如采用混凝表面曝气处理工艺，可使奶牛场废水达到国家排放标准，且处理工艺简单、投资少、运行费低。
The treatment technology of the wastewater from the cow farm was studied in this paper.It showed that by means of the coagulator JF 1,CODcr of the water coagulated fell from 2010mg/L to 563mg/L-691mg/L,NH 3 N fell from 70mg/L to 25mg/L～33mg/L, CM fell from 180 degree to 40～70 degree.The technology of the coagulation aerobic biological treatment was the good,because its not only satisfied with the drainage standards of the state,but also its technology was simple,the cost of the project and working were low and management was easy.
