摘要:本发明公开了一种工厂化水产养殖废水综合处理方法及处理系统。用于工厂化水产养殖的废水处理。将工厂化养殖池底部富含粪便和氨等代谢产物以及剩余饲料的废水输送到斜板沉淀器,粒径较大的粪便和剩余饲料沉淀在沉淀区,接着由机械过滤器将粒径较小的粪便和剩余饲料拦截在过滤前区,废水再进入以硝化细菌为介质的生物滤器,利用硝化细菌将氨转化为硝酸盐,废水再回流至养殖池循环利用,斜板沉淀器沉淀区和机械过滤器过滤前区积累的粪便和剩余饲料以及生物滤器底部积累的絮凝物和沉淀物定期输送到以水培草类植物为介质的植物滤器,循环灌溉水培草类植物以完成固体物的拦截和硝酸盐、磷盐等的吸收等深度处理,并定期回流对机械过滤器进行反冲洗。

Abstract: The present invention discloses comprehensive treating method and system for industrial aquatic cultivation sewage. The sewage containing rich excrement, ammonia and other metabolic product as well as feed residue from the bottom of the industrial cultivation pond is treated successively through deposition of large grain excrement and feed residue in the inclined plate depositor, interception of other excrement and feed residue in the mechanical filter, and conversion of ammonia into nitrate with nitrifying bacteria in the biological filter. The treated sewage is returned to the cultivation pond circularly while the deposited, intercepted and flocculated matters are delivered to the plant filter with aquatic grass plant as medium. The mechanical filter is back flushed regularly.
