, 1990 当废水电导率(20℃)在5000μS/cm以上时,凤眼莲几天内中毒死亡。当电导率在2300μs/cm以上时,凤眼莲生长率,叶绿素含量及a/b比率下降,细胞膜透性增加。凤眼莲适宜的生长范围是电导率1700μS/cm以下。废水中有毒组分使盐分的毒性有所增加,但经活性炭过滤或让其经一段时间自然降解后,毒性明显降低。盐分还使凤眼莲净化效率降低。试验污水中COD、油、氨氮、酚等污染组分的净化效率随污水处理方式不同而有所不同,但在每一处理组中,都是盐分含量居中的试验组的净化效率最高。在本试验条件下,

, 2009 在常温(13～20℃)、不调节pH的条件下,采用短程硝化反硝化预处理低C/N(2左右)猪场废水,考察了反硝化与亚硝化过程,并以经过短程硝化反硝化预处理的猪场废水为进水,分析了厌氧氨氧化的脱氮效果.结果表明,采用短程硝化反硝化预处理低C/N猪场废水,可以达到去除部分COD、部分脱氮、控制出水氨氮和亚硝态氮浓度之比在1∶1左右、pH在7.5～8.0左右的目的,为厌氧氨氧化创造了进水条件,全程COD和总氮平均去除率分别为64.3%和49.1%;经过短程硝化反硝化预处理的猪场废水,其厌氧氨氧化脱氮效果稳定 ...
