Abstract

The invention discloses a biological water treatment agent which is characterized by comprising a composite microbial agent, cellulose, straw powder, coffee grounds and medical stone, wherein the compound microbial agent comprises aspergillus sojae, bacillus licheniformis, geotrichum candidum and pseudomonas fluorescens. The biological water treatment agent provided by the invention has the advantages of good water treatment capacity, wide application range and lower production cost.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a biological water treatment agent and a preparation method thereof. Background technique [0002] Water pollution is a worldwide environmental problem. In recent years, efforts have been made to protect the environment. However, the ecological pollution and prevention and control of various types of rivers are still not optimistic. Eutrophication of water bodies, a large amount of nutrients such as nitrogen and phosphorus flow into lakes and river mouths, causing algae and other plankton to multiply rapidly, and the dissolved oxygen in water bodies Decline, water quality deteriorates, fish and other organisms die in large numbers, form algal blooms, and send out unpleasant smells. At the same time, it also has a negative effect on the local economic development and the construction of the ecological environment in the area, which needs to be treated urgently. With the enhanceme...
