Description

Based on the technique handled spray painting sewage

Technical field

The present invention relates to a kind of technique, more particularly, to a kind of based on the technique handled spray painting sewage.

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 that caused sewage contains in present painting process is more, and its processing is not clean, is polluted after causing discharge Environment.

The content of the invention

It is an object of the invention to overcome the noxious material that caused sewage contains in above-mentioned existing painting process more, at it Reason is not clean, the problem of causing to pollute environment after discharging, devises a kind of based on the technique handled spray painting sewage, the work Skill, especially to caused sewage after spray painting, will not cause environmental pollution, solve existing spray painting for good sewage processing effect During the noxious material that contains of caused sewage it is more, its processing is not clean, the problem of causing to pollute environment after discharge.

The purpose of the present invention is achieved through the following technical solutions：Based on to the technique that is handled of spray painting sewage, in production Spray painting sewage, first after grid removes the large particulate matter such as floating object, enter back into the filtering of multistage filtering pond, then enter multistage and catchment Regulating reservoir, the equilibrium of water quality, water is carried out in the pond, is then quantified sewage, Q=2.0m³/ h, is promoted to coagulation reaction tank Middle pretreatment, occur to generate bulky grain flco after net is caught, adsorption bridging acts on by Water purification medicament and raw sewage, while effectively Colourity, SS and partial organic substances are eliminated, after reaction completely, the water containing flco is flowed into sedimentation basin, then carries out body refuse and moisture From, then water is lifted into Fu Huachi, carry out floatingization processing using the effect of jet pump and ejector；Afterwards by after floatingization processing Water purification flow automatically to sand filter again, acted on using sand filtration, on the one hand can dilute sewage high concentration, reduce processing load；May be used also Balance, matching water, regulation, finally carry out chain scission to the hard-degraded substance in spray painting sewage, can finally ensure stable reach Used to industrial water standard, filtering ponds, sedimentation basin, the heavy mud and sand filter of regulating reservoir and floatingization reaction tank, remaining sludge Elevator pump is lifted into sludge-tank, after filtered dehydration, by dewatered sludge trolley and manual cleaning.

In summary, the beneficial effects of the invention are as follows：The technique is for good sewage processing effect, especially to being produced after spray painting Raw sewage, environmental pollution will not be caused, it is more to solve the noxious material that caused sewage contains in existing painting process, at it Reason is not clean, the problem of causing to pollute environment after discharging.
