Description
Technical field
The utility model relates to a kind of system processing waste emulsified mixture, especially relates to a kind of pH regulator that utilizes and improves the system reclaiming waste emulsion ultrafiltration efficiency.
Background technology
The key of process waste emulsified mixture is exactly breaking milk and removing oil, and breaking milk and removing oil mainly contains this several method: the floating upper method of coacervation, salting-out process, hybrid system, ultrafiltration process and chemical flocculation.Wherein, the effect of ultrafiltration process is reasonable, and ultrafiltration is actual is exactly the process that a kind of sieve aperture is separated, after applying certain pressure by feedwater, polymer substance and colloidalmaterial tunicle stop and pass through, and water and lower-molecular substance then can be purified through filter membrane.In the process of filtering, ultra-filtration membrane can be filtered off the impurity come and polluted, and the treatment process generally taked is exactly by back flushing, carries out back flushing purification to ultra-filtration membrane.Though this method effect is good, but very frequent, and can have impact to the life-span of membrane element for a long time, in addition, during ultrafiltration, waste liquid is very high to the pollution index of film.
Chinese patent CN101311127A discloses and a kind ofly adopts the method for ultrafiltrationmembrane process process high density multiple types waste emulsified mixture and realize the device of the method, belongs to waste water and liquid waste disposal technique field.Main process is " air-dissolving air-float-ultra-filtration membrane-electrofloatation ", adopts high-efficiency dissolved air flotation system, effectively reduces dosing, promote demulsification, dissolved air floatation water takes from follow-up intermediate water tank, and flexible dilution waste strength, adds system run all right and capacity of resisting impact load.Ultrafiltration system selects the ultra-filtration membrane that flux is large, separation efficiency is high, membrane lifetime is long, realizes oily water separation, repeatedly concentrates simultaneously to emulsion, skimming, again processes, decrease discharging of waste liquid after the backflow of ultrafiltration Cleaning Wastewater.Electrofloatation removes the oils of residual oil in water emulsion and dissolving in waste water, reduces water outlet COD value further.When raw water quality changes, activated carbon adsorption unit ensures that effluent quality is up to standard.But this installation method relative complex, causes the structure comparison of system loaded down with trivial details.
Utility model content
The purpose of this utility model is exactly provide a kind of impurity that to decrease in filtration procedure to the pollution of film to overcome defect that above-mentioned prior art exists, also reduce the frequency of back flushing, the pH regulator that utilizes that improve the work-ing life of film improves the system reclaiming waste emulsion ultrafiltration efficiency.
The purpose of this utility model can be achieved through the following technical solutions:
Utilize pH regulator to improve the system reclaiming waste emulsion ultrafiltration efficiency, comprising:

Through pipeline and the tank connected ultrafiltration membrane elements of waste emulsified mixture splendid attire,
It is characterized in that, also comprise the tank connected pH value setting device with waste emulsified mixture splendid attire, the pH value regulating solution in waste emulsified mixture is weakly alkaline.
Preferably, pH value setting device regulates the pH value of solution in waste emulsified mixture to 9-10.
More preferably, pH value setting device regulates the pH value to 9.6 of solution in waste emulsified mixture.
Preferably, pH value setting device passes into sodium hydroxide solution or dilute sulphuric acid in waste emulsified mixture storage can, and the pH value different according to waste emulsified mixture passes into different solution respectively.
Described waste emulsified mixture storage can is built-in with the pH value tester detecting real-time pH value.
Described pH value tester and pH value setting device link, and automatically regulate the pH value of solution in waste emulsified mixture storage can.
Described pipeline is provided with high-pressure pump.
Described ultrafiltration membrane elements carries out ultrafiltration to emulsion, and clean water flows out from rising pipe, and the waste liquid that concentration is high flows out from the waste water mouth of ultrafiltration membrane elements.
Compared with prior art, the utility model adds NaOH or dilute sulphuric acid to waste emulsified mixture, regulate pH=9-10, waste liquid is made to be weakly alkaline, then send in hyperfiltration membrane assembly by high-pressure pump, through ultrafiltration, clean water flows out, the waste liquid that concentration is high flows out from opposite side, for pH value wherein, through studying discovery for a long period of time, when pH value reaches weakly alkaline, especially when pH is increased to 9.6, the charging performance of the colloid in waste water has reached theoretic stationary value, its physicochemical property are in steady state, be conducive to reverse osmosis to run, now not only the effect of ultrafiltration is promoted greatly, the prior impurity that to be the reduction of in filtration procedure is to the pollution of film, also reduce the frequency of back flushing, improve the work-ing life of film.
