Description
Technical field
The invention belongs to sewage treatment fields, and in particular to a kind of to be inoculated with using activated sludge at the microorganism sewage water of flora
Reason method.
Background technology
Sewage mainly has sanitary sewage and industrial wastewater.In water pollution caused by human production activity, caused by industry
Water pollution most serious.Such as industrial wastewater, it is more containing pollutant, and complicated component is not only not easy to purify in water, but also handles
It is relatively difficult.Industrial wastewater is the most important reason that industrial pollution causes water pollution.It accounts for the pollutant of industry discharge
It is most of.Pollutant contained by industrial wastewater is multifarious because of factory's type difference, even same class factory, production process is not
Together, the quality and quantity of contained pollutant is also different.Industry in addition to the waste water of discharge be directly injected into water body cause pollution other than, solid
Waste and exhaust gas also can polluted-waters.Sanitary sewage is the sewage of generation during human lives, is the primary pollution source of water body
One of.Mainly excrement and wash water.Everyone sanitary sewage amount being discharged daily of city is 150-400L, amount and life water
It is flat to have substantial connection.Contain large amount of organic, such as cellulose, starch, carbohydrate and fat protein in sanitary sewage；Also often contain
Pathogen, virus and parasitic ovum；Chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, the magnesium of inorganic salts
Deng.Total feature is nitrogenous, sulfur-bearing and phosphorous height, and post-processing is relatively difficult.People should water conservation, China's actual conditions ratio
More special, water resource occupancy volume per person is few, and spatial distribution is uneven.With Chinese Urbanization's, industrialized acceleration, water resource
Demand gap also increasingly increases.In this context, sewage treatment industry becomes new industry, produced at present with tap water,
It supplies water, drain, Treated sewage reusing industry is in status of equal importance；Ammonia nitrogen is the one kind for causing body eutrophication and polluting environment
Important polluter, at present in the almost all of Polluted water area in China, ammonia nitrogen is all one of main pollutant.Water body richness is sought
Fosterization has endangered all conglomeraties such as agricultural, fishery, tourist industry, also constitutes huge prestige to drinking water hygiene and food security
The side of body.Water pollution especially body eutrophication has become the important influence factor of China's economic development.In trade effluent often
It is one of ammonia nitrogen in sewage main source containing ammonia nitrogen in high density.Therefore, the ammonia nitrogen in trade effluent how is removed at current
A major issue in Industrial Waste Water Treatments.
Currently, existing sewage water treatment method includes biochemical process and burning method, it is biochemical often all to use simple filter type, this
Kind mode device structure is simple, but filter effect unobvious；Also have using high-end reverse osmosis technology, but need to apply pressure
Power causes device structure complicated, and practicability is not strong；Burning method easy tos produce pernicious gas pollution air, and is built in sewage
In object, also it is very difficult to handle sewage composition among these.
