Description
Technical field
The present invention relates to a kind of method of purification of waste water impurity, more particularly to one kind is efficiently gone based on dynamic wave reaction system
Except or reduce waste water in COD, BOD, ammonia nitrogen, S2-Deng the method for pollutant load, belong to wastewater treating technology field.
Background technology
COD (COD), biochemical oxygen demand (BOD) (BOD), ammonia nitrogen, S2-It is the pollutant for causing water pollution Deng pollutant
One of, such as Desulphurization for Coal-fired Power Plant waste water, electroplating wastewater cause water quality to decline and even deteriorate, and influence environment and are pacified with water
Entirely.
The method of the pollutant such as COD is mainly aeration, chemical method and electrochemical method etc. in removal waste water at present, is aerated
The main unfavorable factor of method is that the pollutant efficiency such as removal COD are low, influences energy consumption and removal effect.Chemical method is in oxidizing process
In need to utilize strong oxidizer so that processing cost is influenceed larger by strong oxidizer raw material, and if dealt with improperly, may be increased
New polluter, lacks the market competitiveness.Electrochemical method runs complex operation, and ageing short, disposal ability is low, runs into
This height.
Chinese patent (publication number CN103723884A) discloses a kind of degraded COD, BOD, SS, the sewage disposal side of ammonia nitrogen
Sewage is entered regulating reservoir by method, specific disclosure by mechanical grille first, then flows sequentially through hydrolysis acidification pool, biological contact oxidation
Change pond, neutralization precipitation pond, filtering ponds, split type MBR, CASS reaction tank, counterbalance cell and NF/RO systems, then flow into monitoring pool；Institute
State and be provided with hydrolysis acidification pool hydrolysis acidification bacterium, also add composite organic acid deodorant to hydrolysis acidification pool, and adjust pH value for 5~
6；The DO mass concentrations of the biological contact oxidation pond are controlled to 2~4mg/L；The neutralization precipitation pond adjusts pH value by adding alkali
It is 7~8；By air blower in regulating reservoir, hydrolysis acidification pool, biological contact oxidation pond, neutralization precipitation pond and CASS reaction tanks
Aeration；The sludge of the neutralization precipitation pond, filtering ponds, split type MBR, CASS reaction tank, counterbalance cell and NF/RO systems enters dirty
Sludge dewatering, sewage transport to regulating reservoir, sludge outward transport are carried out after mud sump.The method is mainly using at aeration combination bioanalysis
Reason, the clearance to COD, BOD, SS, ammonia nitrogen is high, can reach more than 95%, and effect is obvious.But the method complex steps,
Device is complicated, and soda acid consumption is big, and processing cost is high.
Dynamic wave principle is a technology for uniqueness, is currently used primarily in filed of flue gas purification, and dynamic wave scrubber is allusion quotation
The fume cleaning device of type, by cleaning solution penetrating air-flow make the momentum of cleaning solution and gas reach balance so as in gas must be through
Road on produce a froth zone, the area is a strong turbulence region, and liquid surface area is big and updates rapidly reaching and has
Effect removing particle and the purpose for removing gaseous contaminant.Up to the present, yet there are no is used to dynamic wave principle process waste water
Report.
