Description
Technical field
It is especially a kind of to be applied to small-sized washing bay the present invention relates to a kind of oil-containing process for treating waste water for car wash and its equipment
Method of wastewater treatment and its integration apparatus.
Background technology
In recent years, with the fast development of China's economy, people's living standard is greatly improved, and city automobile is possessed
Amount is constantly soaring, and incident automobile carwash industry is also rapidly emerged in large numbers, and on the one hand substantial amounts of car wash water exacerbates short water supply,
On the other hand the sewage of discharge causes the pollution to environment again, while the commercial water price of great number occupies the cost of car wash trade
It is high not under, profit reduction, the cost of serving to customer rises.Therefore, vehicle-washing waste water recycling equipment is developed, circular treatment is using washing
Car waste water, is to solve carwash industry water resource waste, reduces the effective measures of environmental pollution.
There are many producer's development and production vehicle-washing waste water recycling equipments in foreign countries, and its technique is more advanced, high degree of automation, waste water
The rate of recovery is high, it is adaptable to large-scale washing bay, and price is expensive.Further, since water pollution degree and pollutant component are different, have
A little operational factors have bigger difference, use and repair inconvenience, are not suitable for China's national situation.
Most of domestic car wash trade is small-sized washing bay.Small-sized washing bay water consumption is small, and available space is few, and fund is relative
Weakness, at present, the treatment technology of domestic various small-sized reclamation sets can divide following a few classes.
1. conventional processes
Following technique is used traditional Waste water reusing device for washing vehicle more：Wastewater from car washer enters after device, is first gone through grid, coarse filter
Except larger debris and sand grains, oil-removing area (general ad hoc oil removing compartment) is entered back into.Inhaled using oil removing sponge, asphalt felt oil-removing area
Attached greasy dirt, oil suction sponge or asphalt felt are periodically removed.Remove the sewage after debris and greasy dirt and enter people's coagulation area, coagulant dosage
Method has a variety of.Sewage after coagulation enters people settling zone, and settling zone uses multigroup swash plate, makes the flco rapid precipitation to be formed.Most
Enter filtration system afterwards, filtration system is to ensureing that it is very big that water quality plays the role of.Filtration system has sand filtration, and active carbon layer filtering is inhaled
It is attached, filter pulp is pressed from both sides, has plenty of hyperfiltration membrane assembly.
Relatively low using said system cost, equipment dependability is higher, and continuous processing ability is strong, and effluent quality is not substantially by temperature
Degree influence, but, technological process link more the shortcomings of big there is also equipment volume.If not using filtering measure, effluent quality
It is difficult to ensure that, the clearance of surfactant is extremely low, causes soluble pollutants accumulation in recirculated water exceeded, effluent quality evil
Change.According to charcoal absorption filtering, effluent quality is good.But if raw water quality is poor, activated carbon can saturation, activated carbon quickly
Layer, filter core etc. often must be changed or regenerated, operation difficulty and processing cost increase.
2. the air supporting of coagulation ten (oil removing)+(filtering)
This technique leading portion is substantially identical with traditional handicraft.Wastewater from car washer is after the big debris of filter screen removal and sand grains, plus people's flocculation
Agent, produce flco, into gas-floating chamber carry out air-flotation process, solid suspension, greasy dirt and detergent by air flotation slot top deslagging
Mouth discharge, the processing visual water quality of water considers whether to carry out filtration treatment.Because air supporting has oil removing effect, it can not use except oilcloth.
This Process for Effluent treatment effect is stable, in wastewater from car washer the clearance of suspension and anion surfactant up to more than 95%,
Treatment operating costs are low, and separated from contaminants is thorough.At present, the main weak point of this technique is that system cost is of a relatively high, one
Secondary property investment is big, and equipment is more complicated, and operating cost is higher.
3. membrane filter technique
This technique allows sewage to pass through a series of filter medium so that the large particulate matter such as silt particle contained in sewage and a part
Organic substance is removed by filtration mechanism.Its filter medium generally uses more medium filter, active carbon filter, precision
Filter and milipore filter etc..
This method is with physical principles such as filtering, absorption and ultrafiltration by the pollutant removal in water, and outlet effect is good, but essence
Filter core in close filtering needs periodic replacement, and milipore filter easily blocks, and replacement cost is higher etc., and factor have impact on the popularization of this technique
Use.
4. membrane bioreactor
Because small-sized The Wash is subject to processing space and cost limitation, biochemical process processing substantially can not using traditional activated sludge process
Energy.At present, domestic and international biochemical process mainly deals with the main process of device using membrane bioreactor (MBR).Membrane biological reaction
Application of membrane in separation engineering in aerobic activated sludge processing system, is replaced conventional biochemical treatment technology by device by membrane module
In secondary sedimentation tank and sand filter, the gravity type glar water separation technology side in conventional method is replaced with membrane separation technique
Formula, has the advantages that high strong adaptability, degradation efficiency, HRT and SRT can be controlled respectively, device is compact, succinct.
Membrane bioreactor is there is also many problems, and first, membrane bioreactor needs successively operation to keep its work
Property sludge activity, be not suitable with that small-sized The Wash wastewater flow rate is small, the big specific situation of water fluctuation.Meanwhile, big portion of winter China
Region-by-region temperature on average is relatively low, and the permeability rate of bioactivity, film is synthermal closely related, permeability rate and sludge activity during low temperature
It is all poor.
In summary several wastewater from car washer handling process methods, all having some limitations property, are particularly in sewage disposal
On key link filtering technique, traditional granular filter material is continued to use substantially, filtering velocity is low, and effect is poor, equipment volume is big, therefore be badly in need of
Further exploratory development adapts to that the small-sized washing bay of China is more, and weather conditions are various, and floor space is small, high treating effect, cost
Operating cost is low, new technology simple to operate, equipment.
