Description
Technical field
The present invention relates to a kind of technique, more particularly, to a kind of based on the technique pre-processed to phosphorized waste water.
Background technology
Sewage, it is often referred to discharge water necessarily polluted, from life and production.Sewage mainly has sanitary sewage, work
Industry waste water and early-stage rainwater.The ill pathogen contaminant of major pollutants, oxygen consumption pollutant, plant nutrient and the poisonous dirt of sewage
Contaminate thing etc..According to the viewpoint of sewage source, sewage can be defined as from the discharge of house, office, business or industrial area and ground
The liquid or water that carry waste of the mixing such as lower water, surface water, snowstorm.Sewage is correspondingly reduced dirty by many classifications
Influence of the water to environment also has many technologies and technique.According to sewage source, sewage can be divided into this four class.The first kind:Industry
Sewage of the waste water from manufacturing, mining and industrial production activities, including lived from the runoff stored, processed with industry or business
Leachate site, and it is other be not sanitary sewage waste water.Second class：Sanitary sewage is from house, office building, office or similar
Sewage；Hygienic sewage；The industrial wastewater mixed in effluent sewerage, including sewerage system in sanitary sewage.3rd class:Business
Industry sewage exceedes nontoxic, the harmless sewage of sanitary sewage from commercial facility and some compositions.Such as sewage from catering business.Laundry
Sewage, animal feeding sewage, sewage etc. caused by hairdressing place.4th class：Overland flow is under rainwater, snow-broth, highway
Water, the water from city and industrial area etc., overland flow does not infilter soil, enters underground water along street and land.Class
In water pollution caused by production activity, water pollution most serious caused by industry.Such as industrial wastewater, it is more containing pollutant, into
Divide complexity, not only be not easy to purify in water, and handle also relatively difficult.Industrial wastewater, it is that industrial pollution causes water pollution
Most important reason.It accounts for the major part of the pollutant of industry discharge.Pollutant contained by industrial wastewater because of factory's species not
Vary together, even same class factory, production process is different, and the quality and quantity of its contained pollutant is also different.Industry removes
The waste water of discharge is directly injected into water body and causes pollution outer, and solid waste and waste gas also can polluted-water.Agricultural pollution is first
Because farming or the reclamation of wasteland make soil surface porosity, the rainfall in soil and also unstable landform, a large amount of silts are flowed into water, increase
Suspension in water.An also major reason is that agricultural chemicals, the usage amount of chemical fertilizer are increasing, and the agricultural chemicals and chemical fertilizer used is only
There is a small amount of attachment or absorbed, remaining overwhelming majority remains in soil and floating in an atmosphere, by rainfall, by rainwash
Wash away into surface water and penetrate into surface water formed pollution.Urban pollution resource be because urban population concentrate, city domestic sewage,
Caused by rubbish and waste gas cause water pollution.Pollution of the urban pollution resource to water body is mainly sanitary sewage, and it is people's day
The mixed liquor of caused various sewage in often living, including the sewage of kitchen, washing room, bathroom and lavatory discharge.The world
On the only discharge of urban area 1 year just up to 500 cubic kilometers of industrial and life contaminated water, and each drop sewage will pollute several times
Or even the water body of decades of times.
The noxious material contained in present sewage is more, and its processing is not clean, and the efficiency handled is low, causes dirt after discharge
Contaminate environment.
The content of the invention
It is an object of the invention to overcome the noxious material contained in above-mentioned existing sewage more, its processing is not clean, and
The efficiency of processing is low, the problem of causing to pollute environment after discharging, devises a kind of based on the work pre-processed to phosphorized waste water
Skill, the technique cause sewage treating efficiency to improve, and eliminate the phosphatization material in sewage so that impurity is reduced, safer, solution
Having determined, the noxious material contained in existing sewage is more, and its processing is not clean, and the efficiency handled is low, pollutes ring after causing discharge
The problem of border.
The purpose of the present invention is achieved through the following technical solutions：Based on the technique pre-processed to phosphorized waste water, table adjusts,
Etching waste liquor flows into etching waste liquor pond, is promoted to phosphorized waste water pond by pump limitation, table is adjusted, phosphorized waste water stirs through diving mixer
After mixing homogeneous, phosphorized waste water reactive tank is lifted into through phosphorized waste water elevator pump, successively the feeding lime into reactive tank respectively
Breast and flocculation aid（PAM ）, through mechanic whirl-nett reaction, insoluble phosphate, the gold of slightly solubility are generated when pH value is more than 9.5
Belong to hydroxide, then flow into stillpot and carry out separation of solid and liquid, the sludge after separation is drained into sludge-tank by gravity flow, by pre-
Handle, the waste water inflow PH after phosphorus and metal ion is eliminated in stillpot and demodulates groove, adds after acid adjusts PH7 ~ 8.5 and flows into certainly
Enter comprehensive wastewater regulating reservoir to be for further processing.
In summary, the beneficial effects of the invention are as follows：The technique causes sewage treating efficiency to improve, and eliminates in sewage
Phosphatization material so that impurity is reduced, safer, solves that the noxious material contained in existing sewage is more, and its processing is not clean,
And the efficiency of processing is low, the problem of causing to pollute environment after discharging.
Embodiment
With reference to embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited only to
This.
Embodiment：
Based on the technique pre-processed to phosphorized waste water, table is adjusted, etching waste liquor flows into etching waste liquor pond, is promoted to by pump limitation
Phosphorized waste water pond, table tune, phosphorized waste water are lifted into phosphorus after diving mixer is stirred homogeneous through phosphorized waste water elevator pump
Change waste water reaction groove, successively respectively into reactive tank feeding lime breast and flocculation aid（PAM ）, through mechanic whirl-nett reaction, in pH value
Insoluble phosphate is generated during more than 9.5, the metal hydroxides of slightly solubility, stillpot is then flowed into and carries out separation of solid and liquid,
Sludge after separation is drained into sludge-tank by gravity flow, by pretreatment, is eliminated in stillpot useless after phosphorus and metal ion
Water flows into PH and demodulates groove, flows automatically behind addition acid regulation PH7 ~ 8.5 and is for further processing into comprehensive wastewater regulating reservoir.
The technique causes sewage treating efficiency to improve, and eliminates the phosphatization material in sewage so that impurity is reduced, and is more pacified
Entirely, it is more to solve the noxious material contained in existing sewage, its processing is not clean, and the efficiency handled is low, after causing discharge
The problem of polluting environment.
It is described above, be only presently preferred embodiments of the present invention, any formal limitation not done to the present invention, it is every according to
Any simply modification, the equivalent variations substantially made according to the technology of the present invention, method to above example, each fall within the present invention
Protection domain within.
