Abstract

The utility model provides a device to treat coating waste water by using the coagulation reaction method, and belongs to the technical field of waste water treatment. The utility model comprises a waste water storage tank, a pretreatment tank, a raw water storage tank, a reaction precipitation tank, a reaction flotation tank, and a purified water tank. A plurality of waste water storage tanks are connected with the pretreatment tank having a COD online controller through pipes. The pretreatment tank consists of an emulsion breaking zone, a PH conditioning zone and a coagulation zone. The outlet pipe of the pretreatment tank is connected with the raw water storage tank, the reaction precipitation tank, the reaction flotation tank and the purified water tank in turn. All of tanks in the device are communicated with an industrial computer through circuits. The utility model premixes various kinds of waste water dynamically by adding the pretreatment tank with the COD online controllers, and adjusts COD in sewerage before coagulating sedimentation reaction to ensure the quality and quantity of water stable and improve the treatment efficiency. The effluent water after being treated with the device can reach the Grade Three Standard of the Integrated Wastewater Discharge Standard.

Description

The coagulating method is handled the coating wastewater device
Technical field
The utility model belongs to technical field of waste water processing, is a kind of device of handling coating wastewater with the coagulating method.
Background technology
Coating wastewater is mainly from industry such as automobile, machineries, in pretreatment procedure and generations such as ability cathode electrophoresis operation and finish paint operation such as pre-degreasing, degreasing, table accent, passivation, phosphatizations.Contain main hazardous and noxious substances in the waste water: nitrite, phosphoric acid salt, oil in water emulsion, tensio-active agent, electrodeposited paint film, alcohol, hydramine, resin, paint, pigment, dimethylbenzene equal solvent, ethylene glycol monobutyl ether, metal ion etc.About general coating wastewater project scale 50T/h~200T/h, waste water COD cr average out to 500~tens thousand of mg/L.Kind of waste water is many, complicated component, and water quantity and quality changes greatly.The method of administering coating wastewater both at home and abroad mainly contains methods such as coagulating sedimentation, air supporting, sand filtration, charcoal absorption, electrocoagulation, Fenton oxidation, SBR, bio-contact oxidation.The method that the improvement coating wastewater adopts as requested has nothing in common with each other.Coagulating sedimentation in the past, air supporting treatment process are because water quality and quantity changes greatly the treatment effect instability.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of device that adopts coagulating sedimentation, air supporting to handle is provided, at water quality and quantity variation operating mode greatly, obtain the stable treated effect, main innovation is to set up the pre-treatment groove that is equipped with COD on-line Control instrument, the COD in the preceding water of coagulating sedimentation reaction is carried out in adjusting, guarantees that water quality and quantity is stable.Specifically implement like this: the coagulating method is handled the coating wastewater device, comprise waste water tank, pre-treatment groove, former water storage tank, reaction precipitation groove, reaction gas floating trough, Rinsing Area, it is characterized in that some waste water tanks respectively pipe connection be equipped with the pre-treatment groove of COD on-line Control instrument, described pre-treatment groove is made up of breakdown of emulsion district, PH regulatory region, coagulation district, pre-treatment groove rising pipe pipeline be linked in sequence successively former water storage tank, reaction precipitation groove, reaction gas floating trough and Rinsing Area, the equal circuit of each groove is connected industrial computer in the device.
The utility model is under industrial computer control, various waste water enter storage tank storage separately, according to the close principle of carrying out the processing of water quality proportioning of each waste water tank high priority individual curing with water level, by the industrial computer fuzzy control waste water is sent into the pre-treatment groove and handle, guarantee that the waste water uniform mixing of each strand different quality water yield and waste water tank waste water in time handles.Handle the principle of waste water: the pre-treatment groove is provided with COD on-line Control instrument, set the waste strength (usually at 700mg/L-900mg/L) of pre-treatment groove, when concentration (or higher) on the low side, waste water by industrial computer instruction input concentration height (or low) is adjusted, and guarantees that pre-treatment groove CODcr is in the finite concentration scope.So just guaranteed the stability that follow-up coagulating sedimentation, coagulation air-float are handled.Add calcium chloride in the breakdown of emulsion district of pre-treatment groove, to contain the emulsification oil mass lower because of waste water, the imperceptible dispersed oil of separating out, with oil absorption material dispersive oil slick absorption on the liquid level is removed, oil absorption material is fixed in the dolly that slides on pre-treatment groove top, oil in the oil absorption material is transported to the other end by capillary theory with oil, is expressed to connect in the oil drum.In the PH regulatory region of pre-treatment groove,, add acid or alkali and in time regulate and control pH value by the pH value in the monitoring groove.The bottom, coagulation district of pre-treatment groove is equipped with sludge outlet, and mud enters the sludge concentration and dewatering device and handles.
Reaction precipitation groove of the present utility model is poly-iron coagulating sedimentation groove, be made up of reaction zone and settling region, the reaction gas floating trough is made up of reaction zone and air flotation zone for poly-aluminium coagulation air-float groove, settling region and air flotation zone bottom are equipped with sludge outlet, described sludge outlet pipe connection sludge concentration and dewatering device.The utility model is by adding the pre-treatment groove that is provided with COD on-line Control instrument, various waste water are dynamically mixed in advance, the COD in the preceding sewage of coagulating sedimentation reaction is carried out in adjusting, guarantee that water quality and quantity is stable, improve processing efficiency, water outlet can reach " integrated wastewater discharge standard " grade III Standard after this device is handled.
