Embodiment
The sterilant chemicals dosing plant that the utility model provides, for adding sterilant to printing-dying wastewater recycling treatment system, to suppress the breeding of bacterium, microorganism etc. in former water.
As shown in Figure 1, in the concrete example of a printing-dying wastewater recycling treatment system, former water by air-floating apparatus 1, more medium filter 2, ultrafiltration system 3, reverse osmosis unit 4, is finally supplied with user successively.The dispensing mouth of sterilant chemicals dosing plant 10 is connected to more medium filter 2 in the water-supply pipe 20 between ultrafiltration system 3.
Wherein, former water is the second pond water outlet through biochemical treatment, the about 1680m of the water yield
3/ d, i.e. 70m
3/ h; 20 ± 5 DEG C of design water temperatures; PH value 6 ~ 9; COD
crindex is≤100, SS(suspended substance) index is≤70 mg/L; Colourity≤40 times.
Air-floating apparatus 1 is used for system to carry out solid-liquid separation, removes the suspension flco in water, reduces the indexs such as chemical oxygen demand COD, biochemical oxygen demand (BOD) BOD, colourity simultaneously.Enter before air-floating apparatus 1, in Xiang Yuanshui, add flocculation agent (polymerize aluminum chloride PAC) and coagulant aids (polyacrylamide PAM), to condense the materials such as suspended substance, colloid, soil ulmin, organism and iron.
Suspended substance, turbidity and partial organic substances in the further removal system water inlet of more medium filter 2.In ultrafiltration system 3, be provided with ultra-filtration membrane, move with pressure-actuated filtration procedure and carry out the particle in Separation of Water by molecular size range by fluid fed tangentially, water, ion and small molecular weight material can be seen through, and colloidalmaterial, particle, bacterium, virus and protozoon are removed.
The sterilant that the utility model chemicals dosing plant 10 adds, for example, be the clorox NaClO liquid of configuration concentration 10%, can play effective germicidal action to former water.Clorox forms hypochlorous acid by hydrolysis, and the nascent oxygen [O] that hypochlorous acid is further decomposed to form again can make the material sex change such as the protein in thalline and virus, thus lethal pathogenic micro-organism.Meanwhile, the chlorion that hypochlorous acid produces can also significantly change the osmotic pressure of bacterium and virosome, makes its cell loss of activity and death.
Reverse osmosis (RO) device 4 is to make to pass through reverse osmosis membrane into water with certain pressure, and removes ion range and the very little organism of molecular weight in water, as bacterium, virus, thermal source etc.Before reverse osmosis unit 4, be provided with cartridge filter 7 and high-pressure pump 8.High-pressure pump 8 can provide enough intake pressures for reverse osmosis unit 4, ensures the normal operation of reverse osmosis membrane.
The filter core that cartridge filter 7 arranges, is used for holding back the mechanical impurity that may leak in preposition pipeline, equipment or the particle breaking, and guarantees the degree of cleaning that reverse osmosis unit 4 is intake.In security personnel filtration unit 7 front and back, add Scale inhibitors and reductive agent (sodium bisulfite NaHSO to former water respectively
3).Scale inhibitors is used for strengthening iron, silicon, organic dissemination and controlling the bright lattice rel of dense water side (LSI) index, even if also can ensure the safety of reverse osmosis unit 4 in the time of change of water quality.Reductive agent is used for eliminating oxidizing substance remaining in former water, the infringement of avoiding oxidizing substance to cause film, and simultaneously effective anti-bacteria is in the growth on reverse osmosis membrane surface.
As shown in Figure 2, described ultrafiltration system 3 is also connected with backwashing system 5, in the time being in water outlet backwash state, via backwashing pump 51, by the water outlet after ultrafiltration system 3 or other device filtrations of system, be delivered to ultrafiltration system 3 from producing pond 50, be used for ultra-filtration membrane wherein to clean waste discharge afterwards.Can be water-in and the water port of ultrafiltration system 3 under water outlet backwash state and normal former water treatment state, staggered water pipe is set, the current under two states are independent of each other.
According to the difference of the difference of raw water quality and pollution condition, when backwash, can further add sterilant by chemicals dosing plant 10 described in the utility model is set, the dispensing mouth of this chemicals dosing plant 10 is connected between backwashing pump 51 and the water-supply pipe 20 of ultrafiltration system 3.For example, can the sterilization of chlorination liquid for the stronger water of microorganism active.
In addition, ultrafiltration system 3 can also further arrange chemical cleaning system 6, recovers the clean of ultra-filtration membrane.According to the difference of pollution condition, Process of Chemical Cleaning can be completed by a step or a few step (comprise alkali cleaning, alkali chlorination are washed, pickling).The acid solution that matting is used can be configuration concentration 31%, commercially pure liquid HCl, and alkali lye can be configuration concentration 40%, commercially pure liquid NaOH.
The matting of washing in order to realize alkali chlorination, can be by the dispensing mouth of chemicals dosing plant 10 described in the utility model and the liquid adding hole of acid solution/alkali lye, is connected to respectively between backwashing pump 51 and the water-supply pipe 20 of ultrafiltration system 3.In described chemicals dosing plant 10, be provided with the circulation line that the chlorine liquid of its input can be circulated in ultrafiltration system 3.In described chemicals dosing plant 10, be also provided with and can make chlorine liquor ratio alkali lye enter evening in water-supply pipe 20, to delay liquid feeding pipeline, prevent that both from reacting in advance.Be for example to increase the length of pipeline to form and delay liquid feeding pipeline, or the valve of delayed start-up can be set on pipeline, etc.In addition, where necessary, can add clorox by the input aperture of chemicals dosing plant 10 and keep total cl concn.
As shown in Figure 3, sterilant chemicals dosing plant 10 described in the utility model, comprises: liquor box 11, volume pump 12 and ducts valve 13.Preferably, liquor box 11 adopts PE(vinyon) material makes; The product that volume pump 12 can be selected meter Dun Luo company of the U.S. or be equal to.In addition, said structure also can be used as the chemicals dosing plant use of flocculation agent, reductive agent or Scale inhibitors etc.
The sterilant that in the utility model, chemicals dosing plant adds, effectively suppresses the breeding of bacterium, microorganism etc. in former water.After the follow-up processing by the each device of printing-dying wastewater recycling treatment system, effluent quality is greatly improved, and effectively reduces the impact of dyeing waste water on environment.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.Read after foregoing those skilled in the art, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
