Problems solved by technology

However, the composite microbial agent needs to add 10%-20% of the initial dosage in each sewage treatment cycle
The addition of bacterial agents in each cycle means that the operating cost will increase with the extension of the operating time on the one hand, and on the other hand it will cause inconvenience in operation, which needs to be improved

Abstract

The invention discloses a compound microbial agent which is prepared from nitrifying bacteria, nitrosomonas, single cell bacteria denitrification salt, salt denitrifying bacterium vibrio cholera, achromobacter denitrificans, bacillus thuringiensis and bacillus subtillis, wherein the total viable count is more than 5.9x10<10>cfu / g; the nitrifying bacteria and the nitrosomonas account for 10 to 20 percent of the total viable count; the single cell bacteria denitrification salt, the salt denitrifying bacterium vibrio cholera and achromobacter denitrificans account for 15 to 20 percent of the total viable count; the bacillus thuringiensis and the bacillus subtillis account for 5 to 10 percent of the total viable count. The compound microbial agent has the benefits that the compound microbial agent is fed at a time, and no bacteria is required to be kept added after the system is stabilized; therefore, the operation cost of sewage treatment is reduced, and the convenience of sewage treatment operation is enhanced.

Description

technical field [0001] The invention relates to the field of sewage biological treatment, in particular to a composite microbial agent and a preparation method and application method thereof. Background technique [0002] The Chinese patent with the notification number 102745821B discloses a composite microbial agent for sludge reduction and its preparation method and application. The composite microbial agent can reduce the amount of sludge from the source without affecting the quality of effluent, so that the discharge of excess sludge in the sewage treatment process is greatly reduced. However, the composite microbial bacterial agent needs to add 10%-20% of the initial dosage in each sewage treatment cycle. On the one hand, the addition of bacterial agents in each cycle means that the operating cost will increase with the extension of the operating time, and on the other hand, it will cause inconvenience in operation, which needs to be improved.
