奶牛场废水处理工艺探讨

STUDIES ON THE TREATMENT PROCESSES OF THE COW WASTE WATER

对奶牛场废水的处理工艺进行了探讨－ 结果表明：奶牛场废水经混凝处理后，ＣＯＤｃｒ从２ ０１０ ｍｇＬ降到５６３～６９１ ｍｇＬ，ＮＨ３ － Ｎ 可从７１ ｍｇＬ降到２５ ～３３ ｍｇＬ，ＣＭ 从１８０ 度降到４０ ～７０ 度；提出了表面曝气－ 混凝－ 复合生物处理的工艺，可使奶牛场废水处理达到国家排放标准，且处理工艺简单，投资省、运行费低。

The treatment processes of the waste water from the cow farm were studied in this paper. It showed that by means of the coagulator JF-1, CODcr of the water coagulated fell from 2 010 mg/L to 563～691 mg/L, NH 3-N fell from 70 mg/L to 25～33 mg/L. were up to. The process of the aerobic coagulation biological treatment was the best, because it was not only from ow farm the drainage standards of the state, but also its process was simple, the cost of the project and working are low, and management was easy.
