Description
Technical field
The present invention relates to the utility appliance in sewage treatment process, specifically a kind of chemical dephosphorization medicament addition device.
Background technology
Because people use agricultural chemicals, chemical fertilizer and phosphorus-containing detergent in a large number, the content of nitrogen and phosphorous in water body is caused to increase, phosphorus is one of principal element causing body eutrophication, cause river, the algae in lake and planktonic organism thus rapidly to breed, cause water quality deterioration, the serious harm environment of human survival.Clear stipulaties in China " the normal pollutant emission standard of cities and towns dirt process " (GB18918-2002), the one-level emission standard A of sewage work's total phosphorus index of construction from 1 day January in 2006 is 0.5mg/L, therefore, it is necessary in sewage disposal, carrying out dephosphorization.
In sewage disposal, the method for dephosphorization mainly contains chemical dephosphorization and biological phosphate-eliminating two kinds of techniques, biological phosphate-eliminating is a kind of phosphorus removing method of relatively economical, but because this technique is easily subject to the impact of readily biodegradable organism amount, structures size etc. in water, cause whole technological process unstable, but also the release again that there is phosphorus causes the possibility of secondary pollution, thus can not ensure that stable water outlet reaches the requirement of state sewage emission standard.And chemical dephosphorization efficiency is higher, and reliable and stable, therefore, in reality, realize further dephosphorization usually through chemical method.
Chemical dephosphorization is the effective means suppressing body eutrophication and reclaim phosphor resource from waste water, and the working cycle of phosphorus in biosphere is different from the circulation of carbon and nitrogen, belongs to the circulation of typical appositional pattern, originates in atmospheric disintegration of rocks, end at the deposition in water.In biosphere, most of phosphorus is uniflux, does not constitute circulation, and therefore phosphoric acid salt also become a kind of unrenewable resource.
Chemical dephosphorization ultimate principle is by adding chemical agent (conventional medicament have: polymerize aluminum chloride, ferrous sulfate, white lime etc.) in sewage, makes it to generate with phosphorus reaction that insoluble phosphate throw out come.Chemical dephosphorization generally comprises chemical precipitating, flocculation, solid-liquid separation three processes.Chemistry precipitating refers to by adding deliquescent salt in chemical agent and sewage in sewage, after phosphoric acid salt mixing, forms the material of particulate state, non-solubility, simultaneously under certain pH value condition, also can produce the oxyhydroxide of non-solubility.This demands medicament can mix in the short period of time with sewage, therefore need to stir rapidly to realize, thus form larger non-solubility solids, make stable elimination of colloid stability, generation flocs unit is contacted with each other, this process and flocculation process under velocity slope or diffusion process effect.In flocculation process, portion phosphate is attracted in the hydroxide surfaces of colloidal simultaneously, gets off in company with colloid coprecipitation, improves dephosphorization efficiency by using.This demands makes the particulate of coagulating agent form the large flocs unit with good sedimentation function by flocculation, final flocs unit is separated by solid-liquid separation step and water body, the waste water be purified and solid-liquid enriched material (chemical sludge), reach the object of chemical dephosphorization.
In chemical dephosphorization process flocculation agent add more flexible, before can preliminary sedimentation tank being added in, also can be added in aeration tank or between aeration tank and second pond, chemical dephosphorization and biological treatment system can also be separated, be that former water adds aluminium salt and carries out coagulation and filtration or before filter tank, add aluminium salt carrying out micro flocculating filter with secondary clarifier effluent.Add before preliminary sedimentation tank, the clearance of preliminary sedimentation tank to organism and SS can be improved, add between aeration tank and second pond, the turbulent flow of channel or pipeline contributes to the mixed effect improving medicament, add after biological treatment system, because biological treatment can make phosphor-removing effect better to the hydrolytic action of phosphorus.What the addition method of current sewage work chemical dephosphorization medicament adopted usually is a kind of liquid flocculation agent chemicals dosing plant, and this device is primarily of compositions such as agitator tank (belt stirrer), liquor box, volume pump, liquidometer, electrical control cubicles, pipeline, all kinds of valve, tensimeter, strainer, bases.Drug concentration needed for sewage disposal, prepares in agitator tank, after agitator stirs, drop into liquor box, carries prepared solution in the system of putting with volume pump (dosing pump) to offeing medicine or specifying.This chemicals dosing plant system is huge, complicated operation, if having a place to break down will cause system stalls, makes troubles to normal dephosphorization.The invention provides a kind of chemical dephosphorization medicament (solid or liquid) directly throwing device, reliably simple and direct, convenient and practical.
Summary of the invention
