奎河污水处理的初步研究

A Preliminary Study on the Treatment of Polluted Water from Kuihe

运用自净及自净后放养水网藻和刚毛藻的方法对奎河污水进行处理．处理后的污水水质得到了明显改善，溶氧量由原来的０．３３ｍｇ／Ｌ增长至１１．１０ｍｇ／Ｌ，ＣＯＤ去除率为９８．６％。处理后的水质对大蒜根尖生长的抑制作用明显降低，污水对大蒜根尖细胞的毒害作用也同时降低。

The quality of polluted water from Kuihe was obvioudy improved by culturing Hydrodictyon and Cladophora in it after self-pusification. The oxygon content of purified water increased from 0. 33 mg/L to 11. 1 mg/L and ratio of COD elimination 98. 6 % two weeks after treatrnent. Inhibition of purified water to the growth of root tip of allium sativum decreased distinctly and toxic effect to cells of root tip decreased as well.
