摘要
为研究水流流速对投加生物促生剂修复水质效果的影响,进行了实验室小试。试验中投加生物促生剂BE10mL/m3,底泥3000mL,分别考察了水流流速为0、0.050、0.065、0.091m/s时污水中总磷、磷酸盐和总氮的去除情况。试验结果显示,在相同的污泥负荷和BE投加量情况下,流速对污染物去除效果的影响较明显;其中影响最明显的是磷酸盐,去除率高达99%;得出最佳流速为0.050m/s。
A lab test for research on the effect of water flow rate on water quality rehabilitation by dosing bio-energize. Under the conditions of dosing bio-energizer BE of lOmL/m^3 and mud of3000mL, TP, phosphate, and TN removals fi'om sewage were investigated with water flow rate of 0m/s, 0.050m/s ,0.065m/s and 0.091m/s respectively. It is shown that, under the conditions of the same sludge load and BE dosage, the influence of flow rate on pollutant removal is more obvious; in it, the influence by flow rate on phosphate removal is the most obvious; its removal rate is as high as 99%; the optimal flow rate is 0.050m/s.
