Description
Technical field
The invention belongs to water-treatment technology fields, and in particular in a kind of in-situ enrichment nutritive salt device and removal surface water
The method of nutritive salt.
Background technology
Since reform and opening-up, China's industrial progress drives of prosperous economy, quality of life improvement, but since environmental consciousness is light
Thin, the treatment facility of sanitary sewage and industrial wastewater relatively lags behind, and numerous surface water bodies is caused to receive different degrees of dirt
Dye.Currently, it is relatively extensive for the Study on treatment technology of sewage and waste water, but the improvement of the surface water body to having polluted
It is very urgent.In addition to organic contamination beyond the region of objective existence, nutritive salt pollutes the sustainable development that also threaten economic society.Currently, China
Most of large size emphasis river, lake and cities and towns, rural area small and medium river channel etc. there is a problem of that nutritive salt is exceeded.
Nutritive salt includes ammonia nitrogen and phosphate etc. in surface water；According to surface water body criteria for classification, I class water body ammonia nitrogen concentrations
Limit value is 0.15mg/L, and total phosphorus concentration limit value is 0.02mg/L, and II class water body ammonia nitrogen concentration limit values are 0.5mg/L, total phosphorus concentration
Limit value is 0.1mg/L, and III class water body ammonia nitrogen concentration limit value 1mg/L, total phosphorus concentration limit value is 0.2mg/L, and IV class water body ammonia nitrogen is dense
Limit value 1.5mg/L is spent, total phosphorus concentration limit value is 0.3mg/L, V class water body ammonia nitrogen concentration limit value 2mg/L, and total phosphorus concentration limit value is
0.4mg/L.As urban economy rapidly develops the quickening with urbanization process, generally there is contaminated phenomenon in urban river,
The water body overwhelming majority of busy areas is especially flowed through by different degrees of pollution, or even seasonality or perennially water body occurs
Black smelly phenomenon.Black and odorous water is divided into slight black smelly and severe black and odorous water, slight black and odorous water ammonia nitrogen concentration 8-15mg/L, severe
Black and odorous water ammonia nitrogen concentration is in 15mg/L or more.Not to the requirement of total phosphorus concentration in the criteria for classification of black and odorous water, but have
Studies have shown that total phosphorus concentration can reach 2mg/L in the black and odorous water of part.
The governing measure used at present includes three kinds of Physical, chemical method and bioanalysis.Physical passes through physical action reality
The migration of existing pollutant improves water body itself self-purification capacity, such as Sediment Dredging, water transfer dilution and artificial aeration etc., such method
High treating effect, it is quick, noxious material is not will produce, but the application limitations such as that there are initial outlays is excessively high, quantities is big.Chemistry
Method enhances the separation and degradation of pollutant by adding chemical agent, and this method quick and high efficient reaction, applicability is wider, but medicament
Dosage is big, and cost is higher, and chemical agent has certain bio-toxicity, easily generates secondary pollution to environment, usually as
Emergency trouble shooting measures.Bioanalysis is the natural metabolism process of enhancement microbiological and water plant, accelerates pollutant consumption, because of investment
Small, operating cost is low, and mild condition has fewer environmental impacts, the features such as can reducing organic pollution concentration to greatest extent, tool
There is larger development potentiality；But the Biochemical method period is long, and by temperature, the environmental factors such as pH and condition of water quality are affected,
Independent role effect is poor, need to often be aided with artificial aeration appropriate etc..
Chemical method and bioanalysis main study subject are the nitrogen phosphorus waste water of high concentration at present, are carried out for low concentration surface water
Research it is less, since surface water body nutrient concentration is generally relatively low, and surface water body volume is larger, it is difficult to carry out at dystopy
Reason, therefore, be badly in need of at present it is a kind of can in in-situ treatment surface water body nutritive salt new method.
