The pretreatment of activated sludge by ultrasound was studied to improve sludge activity as denotation using oxygen uptake rate (OUR). And this was validated by artificial sewage treatment.
研究了超声波对活性污泥活性的影响，用污泥好氧速率OUR来衡量活性，并通过模拟人工废水试验验证。

The microbial properties of artificial soil mixed with brackish dredged sediment, caustic sludge and coal ash were studied, with coastal solonchak and Turbi-Anthric Primosol as the control.
An artificial wetland sewage processing method and system belongs to processing of sewage and sludge, can solve problems of present artificial wetland biological film obstruction and short life.
