小球藻处理养殖废水的初步研究

An Approach to the Treatment of Livestock Farming Wastewater by Chlorella vulgaris

为探讨不同环境条件及细菌对小球藻处理废水效果的影响，通过模拟试验，对小球藻去除养殖废水中有机物、总氮（TN）、总磷（TP）的能力进行了初步研究。结果表明：小球藻在光照条件下对TN、TP的去除效果较之黑暗条件下更优，但对有机污染物的降解能力下降。黑暗条件下的摇床振荡较之静置，更有利于TN．TP的去除，但光照条件下的TN，TP去除则以静置优于摇床振荡。菌藻协同处理废水可以获得比单纯藻或活性污泥更好的处理效果。

A set of simulation tests has been prepared to study the removal of organic compounds, total nitrogen and total phosphorus from livestock farming wastewater by Chlorella vulgaris under various environmental conditions. The results showed that Chlorella vulgaris could remove more nitrogen and phosphorus under light condition than in darkness whilst the degradation of organic compounds would carry out in opposite way. Higher efficiencies of nitrogen and phosphorus removal could be achieved when being shaken in darkness or placed stationarily in the light. Synergism of bacteria and Chlorella was found more effective than activated sludge or Chlorella alone in the wastewater treatment, in which Chlorella had played a major role in nitrogen and phosphorus removal.
