The utility model is in concrete work, and the degreasing cleaning fluid in its pre-treatment degreasing tank needs discharging regularly, contains a large amount of alkali lye and grease in this part degreasing waste water, and PH is more than 14, and oleaginousness is more than 2000mg/L, based on oil in water emulsion.And cleaning by degreasing waste water is divided into twice, contain more alkali lye and grease in the first road rinse water, PH is about 9, oleaginousness contains a spot of alkali lye and grease in the second road cleaning sullage about 100mg/l, PH is about 8, oleaginousness is about 30mg/l, in order to guarantee the workpiece cleaning quality, the water of rinse bath is wanted continuous overflow, therefore produces a large amount of oily(waste)waters.
The utility model is a core technology with breaking milk and removing oil technology under the high pH value condition of waste water and the absorption degreasing technique under the high pH value condition.
After the heating oil eliminator oil removing of degreasing cleaning fluid through having whipping appts, oleaginousness can reach below the 150mg/L, and after the further oil removing of adsorption filtration technology and removing suspended substance, the alkaline water of cleaning is back in the rinse bath then.Finish closed cycle, save fresh water, save the alkali consumption, reclaim greases such as stretching sump oil.
Contain grease and alkali lye that a large amount of workpiece are taken out of after the degreasing in the cleaning sullage.The first road cleaning by degreasing sewage is after collecting, at first regulate pH value by neutralization, pressurization promotes and by the adsorption filtration oil eliminator grease in the sewage is dropped to below the 5mg/l again, suspended substance drops to below the 10mg/l, cleaning water is back to use the second road cleaning sink moisturizing through pressurization, finish the water closed cycle, save fresh water.In order to guarantee the stable of pH value, the PH varitrol is set in sewage recovering system.
The utility model has been owing to adopted above technical scheme, can solve simultaneously from the source application industry pre-treatment degreasing process water saving, reduce blowdown, reduce material consumption and improve the quality of products etc. many-sided technical barrier.Simultaneously, each unit equipment is assembled in and forms an integral body on the steel platform, rectangular structure, and compact construction, rationally distributed, be convenient to operation, install, transport and maintenance; Control is automatically adopted in operation, can realize unattended; Equipment can carry out automatically easily, manual switchover, and is easy to operate.
