raw sludge

The practical operation shows that the treated water can flow back with uniform rate to the raw water distributing well and sludge cake with water content of 80% has been obtained after mechanical dewatering.

工程运行表明经处理后的生产废水能均匀回流至配水井，经机械脱水后污泥的含水率能达到80%以下。

Bio-hydrogen was produced by the pre-processed straw as raw material and digested sludge as the source of natural bacterium through anaerobic fermentative technique.

本文以经预处理的农业水稻秸秆为原料，以活性污泥作为天然厌氧发酵菌群来源，厌氧发酵制取生物氢气。

The results showed that the denitrification capability of the BSAS process was better than SCAS process, due to enhancement of adsorbing measure, and let the return sludge mixed with raw wastewater under anaerobic condition for less than 30 min.

结果表明，后者具有更好的脱氮能力。BSAS工艺采用强化吸附手段让回流污泥与原水在缺氧条件下混合（30min），促进贮存物质的积累，加速内源反硝化作用。

Ratio the raw material and the bulking agent is an important parameter for sewage sludge composting.

试验研究了不同配比的填充料和通气状况对污泥堆肥起始升温的影响.

Raw sludge can be incinerated, provided the water content is sufficiently reduced.

原污泥可以用来焚烧，可以有效地减少含水率。
