【 摘 要 】

One of the new and promising directions in the wastewater treatment technologies and treatment of precipitation is the use of the probiotic agents. A lot of brands of probiotics, which differ in their composition, concentration and cost are offered by the producers on the market. The research results of the "Pip Plus Water" probiotic influence on the concentration of organic contaminants in the model wastewater solution are presented in this article. An additional point is that the changes in the quality indices of the wastewater, which is taken from municipal sewage treatment facilities, because of the contact with a probiotic have been investigated. The characteristics, describing the active sludge compaction process before and after the addition of the probiotic agent, have been obtained. The preliminary study stage has showed that the probiotic agent being considered has a positive impact on the certain sewage quality indicators and the precipitation properties. The ability of "Pip Plus Water" to intensify primary precipitation, wastewater treatment by main indicators (suspended matters, COD) and to improve the sedimentation properties of the excess active sludge has been established.
