Great amount of sludge is produced during aerobic biologically wastewater treatment. Excess sludge treatment process is expensive, thus, reducing excess sludge production becomes extremely impetus.
污水好氧处理会产生大量污泥，剩余污泥的处理成本高昂，减少污泥产量势在必行。
Simultaneously, the excess activated sludge that drained from the sediment pool returned the hydrolysis- acidification pool could be degraded, so the treatment cost of sludge could be lower.
同时，把二沉池排出的污泥回流至水解酸化池进行污泥减容化，还可以降低污泥的处理成本。
Based on Membrane Bioreactor performance, this article introduces the newest wastewater treatment theory and technology of no excess sludge production.
本文介绍了以膜生物反应器为基础的剩余污泥产量最少或无剩余污泥产生的最新的污水处理理论和技术。
Through the secondary treatment, most organic pollutants in raw wastewater transfer into excess sludge, and the sludge discharge quantity (as BOD) will be much higher than that in the effluent.
污水处理厂大量外排污泥势必对受纳环境产生不利影响 ，其程度取决于污泥的无害化或资源化处理和处置方式。
