摘要
在pH为6、7、8、9的条件下,水稻碳化秸秆和玉米碳化秸秆对养猪场废水中COD进行处理;通过研究碳化秸秆对水溶性有机物等温吸附特性的影响,来探讨碳化秸秆对养猪场废水中COD的去除机制。结果表明:玉米碳化秸秆对养猪场废水中COD的去除率高于水稻碳化秸秆,且在p H值为9时去除率最大,在p H为7时去除率最小;碳化秸秆对养猪场废水中COD的去除机制主要以分配机制为主。
Rice carbonized straw and corn carbonized straw to deal with COD of pig farm waste-water under the condition of p H6,7,8,9;By studying the carbonized straw on the influence of water soluble organic matter isothermal adsorption feature, to explore the carbonized straw removal mechanism of COD in pig farm waste-water.The results showed： The corn carbonized straw in pig farm waste-water COD removal rate is higher than rice carbonized straw, and when the p H value of 9 removal rate is the largest, when the p H of7 minimum is removal rate; The carbonized straw in pig farm waste-water COD removal mechanisms are mainly composed of distribution technology.
