Abstract

The invention discloses a compound microbial bacterial preparation and microecological preparation for sewage treatment and applications. An active ingredient of the compound microbial bacterial preparation disclosed by the invention consists of Cellulosimicrobium sp. and Zobellella sp. The active ingredient of the microecological preparation disclosed by the invention is a culture obtained by culturing the compound microbial bacterial preparation with a culture medium. The compound microbial bacterial preparation and the microecological preparation have overall denitrification and phosphorusremoval effects, especially can significantly increase the transparency of black and odorous water, significantly reduce the odor strength of the black and odorous water, can be applied to sewage treatment, especially can be used for treating and repairing the black and odorous water and have a good application prospect.

Description

technical field [0001] The invention relates to a composite microbial agent for sewage treatment, a microecological agent and its application. Background technique [0002] Landscape water bodies such as lakes and rivers in cities are an important part of urban human settlements, but due to their characteristics of easy pollution, small water environment capacity, and poor self-purification ability of water bodies, they are easy to become the recipients of domestic sewage, rainwater and garbage for residents. body, resulting in a large consumption of dissolved oxygen in the water body, resulting in the lack of oxygen in the water body and a black and odorous state, causing the entire ecosystem to be in crisis. Urban rivers appear black and smelly, turning into black and smelly water bodies, which has become a common pollution problem in many large and medium-sized cities, seriously affecting the lives of residents, the image of the city and the ecological environment.
