查询词典 oligochaete

Finally it was found that the present of Oligochaetes not only brought better characteristics of the sludge such as good settleabilily, but also minished the membrane fouling greatly, and did not affect the effluent quality. And most important of all, in the case of almost no sludge production discharged, MLSS could be kept nearly 4000mg/L in more than 40 days when Oligochaete was present, which meant that there was no sludge production in the process.

同时，试验还发现大量蠕虫的存在，对出水水质的影响不大，但能够改善污泥特性，减缓动态膜污染，污泥浓度能自平衡于4000mg/L左右；并在近40天内，在没有排泥的情况下，无污泥量的增加，即实现了减量剩余污泥排放。
