Abstract

The present invention is efficient ecological sewage treating promoter and its preparation process. The efficient ecological sewage treating promoter consists of microbe seeds 5-15 wt%, nutrient matters 5-15 wt%, adsorbent 35-45 wt% and puffing agent 35-45 wt%. The preparation process includes the following steps: collecting fresh active sludge within 6 hr from the aeration basin of sewage treating yard; screening out from the active sludge ammonifying bacteria, nitrifying bacteria, denitrifying bacteria, phosphophilic bacteria and actinomycete; compounding microbe seeds, amplifying culturing and drying to obtain dry mixed microbe seeds; compounding the microbe seeds, nutrient matters, adsorbent and puffing agent in the said proportion; and re-drying to water content in 4-6 wt% to obtain the efficient ecological sewage treating promoter. The present invention can improve the microbe colony in soil effectively, shorten technological starting period, and raise ecological sewage treating effect.

Description

Technical field: [0001] The invention relates to a treatment method for purifying sewage by using underground infiltration and artificial wetland technology in sewage treatment, in particular to a sewage treatment accelerator and a preparation method thereof. Background technique: [0002] With the development of society and the growth of population, the problem of sewage treatment has become increasingly prominent, especially a large amount of domestic sewage has been produced, which contains a large number of organic pollutants, pathogenic bacteria and protozoa. The domestic sewage pollution problem is particularly prominent in the suburbs, villages and villa areas far away from the sewage pipe network. At present, in sewage ecological treatment projects, underground infiltration and constructed wetland technologies are mainly used. The disadvantages are that the indigenous microbial population in the soil is single, the process start-up period is long, and the treatment l...
