摘要
一种新型水质改良剂对池塘水质的影响研究结果表明,施用新型水质改良剂对水化因子有很大影响,使池塘DO升高,COD、NH4+-N、NO2--N降低,pH值变化平稳;1次施用的效果持续时间约为15 d,在池塘中施用这种新型水质改良剂可达到改良水质的目的。
Influence of a new ameliorative agent on water quality had been studied in freshwater pond. The results showed that using of the new ameliorative agent had a great effect on chemical factors. The content of DO rose ,but the content of COD ,NH4^＋-N and NO^2--N reduced and pH value changed smoothly. The effect sustained 15 days. Using of the new ameliorative agent could improve water quality in freshwater pond.
