摘要
为研究环境友好、不产生二次污染的新型养殖废水处理技术,采用卤虫Artemia salina和小球藻Chlorella vulgaris联合培养的方法,在实验室条件下进行了卤虫和小球藻联合培养对养殖废水中悬浮物、氨氮和总磷处理效果的试验,试验设0 (空白)、100、200、400 ind./L 4个卤虫无节幼体密度组。结果表明:卤虫与小球藻联合处理养殖废水第7天时悬浮物含量降至最低,各试验组与空白组有显著性差异(P<0. 05);第17天时400 ind./L卤虫密度组氨氮去除率高达93. 53%,200 ind./L卤虫组总磷去除率达91. 39%;卤虫生长试验显示,在养殖废水中虫藻联合培养的卤虫体长从第5天开始显著高于海水组(P<0. 05);卤虫与小球藻联合培养处理养殖废水,对氨氮和总磷的去除率均超过90%,最佳试验组为200ind./L卤虫组。本研究结果为处理水产养殖废水开拓了新途径,并能切实应用于生产实践。
Naupli of brine shrimp Artemia salina was reared in aquaculture wastewater at density of0(control group),100,200,and400individuals/L for7days and then co-cultured with green alga Chlorella sp.for17days in a laboratory to explore brine shrimp-green alga combined treatment effect on removal of suspended substance(SS),ammonia nitrogen and total phosphorus in aquaculture wastewater.The SS content was found to be to the minimum in aquaculture wastewater7days after treatment,with significant difference between each experimental group and the control group(P<0.05).The maximal removal rate(93.53%)of ammonia nitrogen was observed in the 400 ind./L group,and the maximal removal rate of total phosphorus(91.39%)at 200 ind./L group in17day treatment,with significant difference in body length of the brine shrimp between brine shrimp-green alga combined treatment group and the control group(P<0.05).The removal rates of ammonia nitrogen and total phosphorus were as high as 90% from aquaculture wastewater in brine shrimp-green alga combined treatment,with the best removal effects of ammonia nitrogen and total phosphorus in 200 ind./L group.The findings indicate that brine shrimp-green alga combined treatment of aquaculture effluent not only provides live food for aquaculture to reduce costs,but also deals with aquaculture wastewater as a new effective and practical way.
