Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
A kind of middle water recycling device of trade effluent; Be divided into Wastewater Pretreatment part 1 and middle water reuse part 2, Wastewater Pretreatment part 1 mainly comprises the following strainer that is provided with mutually successively: quartz sand filtration device 3, deep bed filter 4, ultra-filtration equipment 5, activated charcoal filter 6, heavy metal chelating device 7, accurate filter 8; Middle water reuse part 2 mainly comprises middle water recycling device.
Wherein: quartz sand filtration device 3 disposes one, and select to use diameter be that the silica sand of 1～4mm is as filler.Deep bed filter 4 uses filter bag as filter core, utilizes pressure to see through filter cloth by water, to tackle in the water than small granular suspended matters matter; Alleviate the pressure of subsequent disposal, in the present embodiment, deep bed filter 4 disposes 3; 3 deep bed filter 4 are in parallel installed with, and are used alternatingly, and increase at 1 deep bed filter 4 hydraulic pressure; When water flow reduces, switch other 1 use.Ultra-filtration equipment 5 is mainly used in waste water is carried out advanced treatment, can move normally to guarantee follow-up anti-pollution reverse osmosis membrane assembly 13, and ultra-filtration equipment 5 uses special membrane material, removes COD (COD) and colloid in the water, plays the effect that purifies water.Activated charcoal filter 6 disposes 1; In fill out high quality fruit shell mould activated carbon; Utilize the surface-area of activated carbon big; Materials such as the fine particle in characteristics such as the excellent adsorption absorption waste water, colloid, COD, the filter core bottom of activated charcoal filter 6 is filled out and is provided with a small amount of macrobead silica sand as supporting layer, prevents that the leakage of gac from influencing effluent quality.Heavy metal chelating device 7 disposes 1, adopts the organic composite material Ke Bennaite (CARBONITE) of Shanghai Lu Bo novel material ltd development, the Cu in the absorption waste water
2+, Ni
2+Etc. heavy metal ion, clearance can reach more than 90%, and this material is compared with traditional sorbing material, not only has the adsorption and enrichment effect, has ion exchanging function simultaneously.Accurate filter 8 disposes 1, is used to tackle the particulate matter that heavy metal chelating device 7 is revealed, and the protection ultra-filtration membrane purifies water.Above-mentioned each strainer all adopts the carbon steel line with rubber, and its upper end is provided with venting port, the bottom is provided with sewage draining exit; The ingress and the exit of each strainer are provided with tensimeter.
In addition, middle water recycling device mainly comprises being connected successively intermediate water tank 9, topping-up pump 10, security personnel strainer 11, HPP 12 and anti-pollution reverse osmosis membrane assembly 13 is set.Wherein: security personnel's strainer 11 disposes 1; Waste water is before getting into the r-o-membrane module after the pre-treatment; For the filtrate of avoiding previous filter leaks and the suspended matter of failing complete filtering get in the anti-pollution reverse osmosis membrane assembly 13; The filtering accuracy of security personnel's strainer 11 is 5 μ, gets into HPP 12 and anti-pollution reverse osmosis membrane assembly 13 scratching films surface to prevent particle.HPP 12 is for anti-pollution reverse osmosis membrane assembly 13 provides enough intake pressures, guarantees the normal operation of anti-pollution reverse osmosis membrane assembly 13.According to the characteristic of r-o-itself, need there be certain impellent to remove to overcome resistances such as osmotic pressure, could guarantee to reach the water production rate of design.Anti-pollution reverse osmosis membrane assembly 13 is cores of native system, and the water of reverse-osmosis treated can be removed in trace or a small amount of heavy metal ion through omitting like heavy metal chelating device 7 backs.This assembly is a composite package, and upper layer is the polymeric amide material, and thickness is about 2000 dusts, and is supported by one deck micropore polysulfones layer, can bear high pressure, and mechanical tension and chemical erosion are had better resistivity, and it is big to produce water flux.
Below the simple working method of present embodiment down of setting forth:
For the processing of chromate waste water, at first handle for chromium wherein through broken chromium pond 14, become trivalent chromium to hexavalent chrome reduction.The best pH value of chromate waste water so can add the pH value of acid (general optional hydrochloric acid HCl) adjustment waste water through the PH table, is handled chromic requirement to satisfy between 2-3; Satisfying under the pH value condition through adding burnt (Na
2S
2O
5) become trivalent chromium to hexavalent chrome reduction, and the degree that broken chromium is handled can be controlled through ORP (redox potential), and generally ORP is presented at 340 when following, and sexavalent chrome is reduced basically.Handle through broken cyanide water tank 15 for cyanide wastewater, broken cyanide is influenced by temperature and PH mainly, cyanide wastewater at pH value greater than 11 o'clock; Speed of response is accelerated; So pH value will control to more than 11 when Treatment of Cyanide-containing Wastewater, become nontoxic compound to cyanide oxidation through adding Youxiaolin (NaClO), the degree that same broken cyanide is handled also can be controlled through ORP; General ORP is presented at 225 when above, and prussiate is gone up oxidized abolishing basically.
The waste water of removing chromium, cyanogen gets into quartz sand filtration device 3 after settling tank 16 sedimentations, in quartz sand filtration device 3, filter and have little time the macrobead suspended matter in settled metal hydroxides and the waste water, and get into deep bed filter 4; In deep bed filter 4,, go forward side by side into ultra-filtration equipment 5 through more short grained suspended matter in the filter cloth interception water; COD material in ultra-filtration equipment 5 in the filtered wastewater and some colloids, and get into activated charcoal filter 6; Materials such as the fine particle in the filtered wastewater, colloid, COD once more in activated charcoal filter 6 guarantee its water outlet SDI (pollution index)≤3, get into heavy metal chelating device 7; In heavy metal chelating device 7, remove Cu
2+, Ni
2+Etc. heavy metal ion, and get into accurate filter 8, in accurate filter 8, remove the particulate matter of revealing in the heavy metal chelating device 7, purify water, and accomplish pre-treatment waste water.
Waste water gets into intermediate water tank 9 after having passed through pre-treatment, the beginning Treatment for Reuse.Waste water gets into security personnel's strainer 11 under the supercharging of topping-up pump 10; Security personnel's strainer 11 is identical with the effect of accurate filter 8; The filtrate that removal is revealed in preprocessing process and fail the suspended matter of complete filtering, and under the effect of HPP 12, get into anti-pollution reverse osmosis membrane assembly 13, remove trace or a spot of heavy metal ion; Accomplish last processing, make the middle water after the processing carry out reuse.Certainly, be not that 100% waste water can both reuse, through after the primary treatment, there is 30% dense water to reflux approximately, restart primary treatment, constantly circulation is until fully can reuse.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
