【摘要】：试验利用沼液处理液养殖目标藻种普通小球藻(Chlorella vulgaris),考查普通小球藻的生长状况和其对沼液中总氮、氨氮、总磷和COD等主要污染物的去除情况。结果表明:沼液经梯度处理后普通小球藻总体生长情况逐渐增强,依次为:沉淀上清液沼液沉淀-混凝出水液沼液沉淀-混凝-吸附出水液。沼液处理液能有效促进藻体叶绿素的积累,总脂积累情况介于6.94%~23.82%之间。对沼液的净化效果,沼液处理液稀释组中沼液吸附出水稀释液(X-W)25%组的表现最好,总氮、氨氮、总磷和COD去除率分别为80.32%,83.88%,93.90%和20.00%,沼液处理液与BG11培养基的调配液组中表现最好的是沼液吸附出水调配液(X-B)10%组,去除率分别为88.37%,93.57%,97.40%和22.05%。试验的研究将为沼液的资源化处理提供理论依据。
[Abstract]:Chlorella vulgaris (Chlorella vulgaris), a target algae species, was cultured with biogas liquid. The growth status of Chlorella vulgaris and its removal of main pollutants such as total nitrogen, ammonia nitrogen, total phosphorus and COD in biogas were investigated. The results showed that the total growth of Chlorella vulgaris was gradually enhanced after the biogas was treated with gradient. The order of growth was as follows: precipitation supernatant biogas precipitation-coagulation effluent biogas precipitation-coagulation-adsorption water. The total lipid accumulation was between 6.94% and 23.82%. For the purification effect of biogas liquid, the best performance was in the dilution group of biogas liquid adsorbing water diluent X-WN 25%, total nitrogen, ammonia nitrogen, total nitrogen, ammonia nitrogen, The removal rates of total phosphorus and COD were 93.90% and 20.00%, respectively. The best performance in the mixed liquid group of biogas treatment liquid and BG11 medium was the group of adsorbed effluent mixture X-B10%, and the removal rates were 88.377.57% and 22.05%, respectively. The experimental study will provide theoretical basis for the treatment of biogas wastewater.
