摘要
从磷酸盐化学沉淀和藻类吸收两个方面探讨了高效藻类塘中磷酸盐的去除机理。首先通过化学沉淀及其解析解释了高效藻类塘中pH与磷酸盐浓度昼夜变化规律;其次测定了pH=7.5时藻类对磷酸盐的日均吸收速率;最后对高效藻类塘中磷酸盐浓度的变化规律进行了总结。
The mechanism of phosphate removal in high rate algal ponds （HRAPs） is discussed in terms of phosphate precipitation and algal phosphate uptake. Ftrstly, diurnal variations of pH and phosphate concentration in the HRAPs are interpreted upon the theory of phosphate precipitation and its resolution.Secondly, the average uptake rate of phosphate by algae under pH of 7.5 is determined. Finally, some variation rules of phosphate concentration in high rate algal Fond are summarized.
