Description
Technical field
The present invention relates to technical field of sewage more particularly to a kind of microbial enzyme compound formulation and preparation method thereof and
Its application in processing trade effluent or landfill leachate.
Background technique
With the development of industrialization with the increase of urban population, urbanization constantly expands so that water and useless, dirt are used in city
Water discharge amount is continuously increased, and exacerbates short and water body the pollution of water resource, city domestic sewage and trade effluent or rubbish
Percolate improvement has become the focus being concerned in environmental protection.In recent decades, the processing technique of municipal sewage is continuous
Development, based on aerobic microbiological processing technique, is broadly divided into activated sludge process and biofilm two major classes treatment process.It is conventional
Nitrogen, the phosphorus treatment effect of activated sludge process are bad, are not easy to reach discharge standard, thus when sewage treatment by Aerobic Process for Treatment with detest
Oxygen processing combines, and further removes ammonia nitrogen.
EM (effective microorganisms) technology is university, Ryukyu, early 1980s Japan than praising according to husband
What professor et al. proposed, EM bacteria agent is one kind centered on photosynthetic bacteria, and nitrogen-fixing bacteria and deposits, breeds, using special fermentation
Technique, the composite microbial that the aerobic and anerobe that carefully screen are mixed in appropriate proportions and are turned out
Object microbial inoculum.The utility and its secretory substance that various microorganisms generate in its growth course become micropopulation growth
Matrix and raw material one complexity formd and stable microflora, hair by mutual this symbiosis Relationship With Proliferation
Wave multiple functions.Currently, EM bacteria agent agricultural, animal husbandry, aquaculture, in terms of achieve good application effect
Fruit.
After applying EM bacteria agent in sewage, beneficial bacterium can be made to occupy superiority quickly, absorb the nutrients in waste water
Matter (most of organic matter and part inorganic matter), so that sewage becomes clear, stench is eliminated, ecological environment is restored.The world
On there are many country using EM bacteria agent carry out sewage treatment, obtain relatively broad application has Japanese, Dutch, new west
Blue, Pakistan, China and Thailand etc..Sewage boiling water is handled using EM bacteria agent, effluent quality is good, and biofacies increases, and sludge produces
Amount is few, may also suppress the generation of dross.
