复配优势菌用于污水处理及污泥减量的研究

Study of wastewater treatment and sludge reduction by compound ascendant fungi

从特定活性污泥中筛选优势菌与EM菌复配,通过正交试验,确定复配优势菌的最佳投加量,并经动态模型进一步验证试验结果。结果表明,根据污水特点添加不同量的复配优势菌,不仅有效地减少了剩余污泥的产量,而且提高了出水指标。

The ascendant fungi have been filtrated from given activated sludge to compound with EM. Through orthogonal experiment,the best additive quantity can be confirmed. And the dynamic model test validates further the experiment result. It shows that according to the characteristics of wastewater,different quantities of compound ascendant fungi are added,which not only reduce the production of surplus sludge but also improve the indexes of effluent water.
