The method that kind handles sewage using the system.
Background technique
Microbial method sewage treatment is the technology being most widely used in water process, as discharge water quality improves, especially
The raising that nitrogen phosphorus ligands require, enhancement microbiological function become hot spot.There are two types of practices wells, one is adding extraordinary microbial inoculum,
Reach promotion processing function effect by being inoculated with microbial inoculum, but there are the problems such as costly, enhancement microbiological type is single.It is another
It is to add the substances such as Powdered Activated Carbon, magnetic powder to promote micro organism quantity and type, improve sludge quality, such as reduces sludge bulking
Risk, granular sludge etc., so that enhancement microbiological purification function, promotes the removal effect of nitrogen phosphorus.
In recent years, more by the active research of magnetic powder enhancement microbiological, magnetic powder magnetization facilitates mentioning for microbial activity
It rises, is also convenient for sludge and is separated from water.In patent 201120104095.3 " magnetic loads A2/O sewage-treatment plant ", magnetic powder is added
It needs to add flocculant in the process." magnetic loads reflux biologic process for treating sewage and dress in magnetic mud to patent 201210382715.9
Set system " in it is only in situ in flow back magnetic sludge, do not carry out exteenal reflux so that in magnetic sludge microorganism lack anoxic, anaerobism,
Aerobic circulation stimulating course, is unfavorable for the removal of nitrogen and phosphorus pollutants, especially needs anoxic/aerobic alternate nitrogen removal and detests
The removal of oxygen/aerobic alternate phosphorus.
With the exploitation of phosphorus ore, for phosphorus ore reserves close to lower limit, the regeneration of phosphorus has become the Research Emphasis of industry, around from
Phosphorus is extracted in sewage carries out the regeneration research of phosphor resource as inevitable.It is mostly crystallisation, including MAP and HAP that phosphorus is extracted in sewage.
MAP method is suitble to the high-density phosphorus water of 100-200mg/L, and HAP method is more suitable for phosphorus concentration in the sanitary sewage of 5-10mg/L.In recent years
Some researches show that externally-applied magnetic field helps to induce HAP crystallizing-dephosphorizing, and magnetic field energy changes the physicochemical property and structure of substance, suitably
Magnetic field processing can promote crystal growth, the time required to reducing crystallization, increasing crystal yield simultaneously can improve product quality.Through magnetic field
HAP crystallization is induced after processing, P elements proportion is higher, is more advantageous to and removes more phosphorus from sewage.
