The result showed the mutagenic activated sludge had remarkable effect and application potential in pulping wastewater treatment. Comparing with common activated sludge, the mutagenic activated sludge was more suitable for lignose decomposition and had high decomposing efficiency.展开更多
通过现场调查、盆栽试验和采样分析的方法,研究了用草浆废水灌溉海涂芦苇湿地对土壤理化性质、微生物数量和芦苇生长的影响。结果表明,灌溉后土壤中的有机质、N 和 P 含量有所增加,土壤盐份含量明显下降,同时土壤中的细菌、放线菌和霉...通过现场调查、盆栽试验和采样分析的方法,研究了用草浆废水灌溉海涂芦苇湿地对土壤理化性质、微生物数量和芦苇生长的影响。结果表明,灌溉后土壤中的有机质、N 和 P 含量有所增加,土壤盐份含量明显下降,同时土壤中的细菌、放线菌和霉菌的均大幅度增加。一定质量浓度的造纸废水灌溉对湿地芦苇的生长有促进用、对土壤的性质有改良作用,但废水质量浓度过高则对土壤的理化性有不利影响。本文推荐造纸废水灌溉海涂芦苇湿地的适宜质量浓度为 1000 mg/L 以下。展开更多
文摘Instead of pure bacteria, induction mutation of activated sludge by ultraviolet (Uv) was studied and used to treat pulping wastewater by continuous- flow. The result showed the mutagenic activated sludge had remarkable effect and application potential in pulping wastewater treatment. Comparing with common activated sludge, the mutagenic activated sludge was more suitable for lignose decomposition and had high decomposing efficiency.
