Abstract
The utility model relates to an efficient emulsion wastewater treatment device, which adopts the technical scheme that the efficient emulsion wastewater treatment device comprises a feeding tank and afilm component; the film component is respectively connected with a feeding tube, a penetrating liquid conveying tube and a concentrated liquid conveying tube; the other end of the feeding tube is communicated with the feeding tank; and a circulating pump is arranged on the feeding tube. The efficient emulsion wastewater treatment device is characterized by further comprising a circulating tank;an overflow port is formed on the lateral wall of the circulating tank and positioned above the feeding tank; the other end of the concentrated liquid conveying tube is connected with the circulatingtank; and the lower part of the circulating tank is communicated with the circulating tube communicated with the feeding tube. After a film is filtered, the concentration of a surface active agent inconcentrated liquid is reduced, and then emulsion is broken and grease floats in the circulating tank. An oily layer at the upper part of the concentrated liquid smoothly overflows back to the feedingtank and floats on the surface of raw liquid to be removed more easily by an oil wiper. After residual oil is immediately discharged outside a film filtering system, the film blockage factors are reduced, so that the cleaning frequency of the film component can be further reduced greatly.
Description
Technical field
The utility model belongs to water-treatment technology field, is specifically related to the efficient treatment unit of a kind of emulsifying liquid waste water.
Background technology
In the rolling iron and steel process, the band steel can produce distortion heat under the effect of rolling load, thereby influences final product quality.For eliminating this influence, iron and steel enterprise uses emulsion that the band steel is cooled off and lubricates usually, has but produced a large amount of cold-rolling emulsion waste water thus.Mainly contain compositions such as mineral oil, tensio-active agent, antioxidant in the cold rolling wastewater, the emulsification under the effect of tensio-active agent of its mineral oil in fluid has formed very stable dispersion system.Use processing oily(waste)waters such as air supporting method, absorption method, biochemical process, chemical method and all be difficult to obtain the ideal effect.
The ceramic membrane technology is used to handle and has just demonstrated extremely strong competitive power after the oily(waste)water, have that the membrane module floor space is little, the refiltered oil quality better, during works better not chemical agent consumption do not produce new advantages such as mud yet.Fig. 1 is the structural representation of existing cold-rolling emulsion wastewater treatment equipment, and device mainly comprises charging tank 1, membrane module 7 and the feeder sleeve 9 that connects charging tank 1 and membrane module 7.Emulsifying waste water is divided into penetrating fluid and dope two portions after membrane module 7 filters, most surfaces promoting agent in the waste water enters in the penetrating fluid and is sent to given place, and the grease in the dope reduces breakdown of emulsion because of surfactant concentration and is recycled in the charging tank 1 by dope transfer lime 6.Charging tank 1 is bulky, is divided into three chambers by upper spacer 4 and lower clapboard 5 successively: be provided with oil wiper 2 in first chamber, be used to collect the grease of come-up; Simultaneously, the macrobead suspended substance in the waste liquid precipitates in first, second chamber, and supernatant liquid covers lower clapboard and enters in the 3rd chamber, as the stock liquid of delivery film assembly 7.
It is desirable that this device seems, but very easily stifled in actual applications film will clean once basically in 2 days; Frequently washing film had both increased the clean and maintenance cost of device, had had a strong impact on the processing efficiency of device again, thereby had delayed ordinary production.This is because dope is very fast from membrane module output back flow velocity, directly pours in the charging tank and can stir by the generation intensive; Simultaneously, still contain the tensio-active agent of higher concentration in the waste water, the intensive stirring can make grease emulsification again, causes that greasy dirt concentration constantly rises in the stock liquid, and film pollutes aggravation, and membrane flux continues to descend, and cleaning frequency improves.
In addition, in order to improve membrane flux, also need waste water is heated in advance, and then be delivered to membrane module; This process will consume a large amount of heat energy.
Summary of the invention
The purpose of this utility model is that a kind of processing efficiency height, floor space are little, the cold-rolling emulsion wastewater treatment equipment of save energy in order to provide.
For achieving the above object, the technical scheme that the utility model adopted is: the efficient treatment unit of a kind of emulsifying liquid waste water, comprise charging tank and membrane module, membrane module is connected with feeder sleeve, penetrating fluid transfer lime and dope transfer lime respectively, the other end of feeder sleeve is communicated with charging tank, and feeder sleeve is provided with recycle pump, and described device also comprises circulation tank/groove, have overflow port on circulation tank/groove sidewall, overflow port is in the charging tank top; The other end of described dope transfer lime links to each other with circulation tank/groove; Circulation tank/groove bottom is connected with the circulation tube that connects with feeder sleeve.
Described recycle pump is installed on one section feeder sleeve between circulation tube and the membrane module, and one section feeder sleeve between circulation tube and the charging tank is provided with inlet valve.
For fear of splash, described overflow port is connected with upflow tube, and the upflow tube the other end feeds charging tank.
In order to remove the oil slick on the liquid level, described charging tank top is provided with oil wiper; The charging tank bottom is provided with sewage draining exit, so that periodic cleaning is deposited on the dirt of charging tank bottom.
Described device also comprises the paper tape filter, and the filtrate outlet of paper tape filter is in the charging tank top, and waste water drops down in the charging tank after the paper tape filter filters.
The utility model has been set up circulation weir tank/groove on the basis of conventional film filtration unit, make it keep certain circulation spillway discharge by the control inlet valve.Through the buffering of circulation tank/groove, the dope flow velocity is controlled, also provides fully many time for dope breakdown of emulsion, grease come-up simultaneously.Steady, the Residual oil content height of the liquid levelling that overflows back charging tank; Residual oil floats on feed liquid surface thereby is removed by oil wiper easilier.Because the Residual oil that breakdown of emulsion is separated out in the dope can be discharged outside the film circulated filter system in time, stifled film factor reduces and then greatly reduces the cleaning frequency of membrane module.With the ceramic super-filtering film assembly is example, adopts device of the present utility model to handle cold-rolling emulsion waste water, and the cleaning interval extended to about 1 month by original 2 days, the device stable and reliable operation, and processing efficiency promotes greatly.
In addition, circulation tank/groove has also played the effect of accumulation of heat: behind membrane filtration, the dope temperature generally can rise to 40～60 ℃; This part thermal storage fluid is stored in the circulation tank, and as required by circulation tube delivery film assembly, like this then need not the waste water of delivery film assembly is heated in advance.
Inlet valve can be used for regulating the internal circulating load of the feed liquid of delivery film assembly, can either reach the purpose of control feed temperature, and can control the oil slick that the dope breakdown of emulsion separates out again can in time overflow.
Meanwhile, the utility model provides technical possibility for the volume of reduction charging tank, and circulation tank/groove can unsettledly be located at the charging tank top, thus the floor space of reducing whole device on the whole.
