The utility model is achieved through the following technical solutions: a kind of tube type filter membrance method is processed the heavy metal wastewater thereby heavy metal and is reclaimed and waste water reuse system, and it comprises that the raw water collection groove, pH regulator groove, concentrated case, microfiltration membrane device, the micro-filtration that are communicated with successively by pipeline produce water tank, char filter, secondary filter, high-pressure pump and reverse osmosis unit; Concentrated case also is communicated with sludge thickener, sludge pump and pressure filter successively by pipeline.
Be connected with transferpump between concentrated case and microfiltration membrane device, be connected with backwashing pump between microfiltration membrane device and micro-filtration product water tank; Produce between water tank and char filter at micro-filtration and be connected with lift pump.
Be provided with the pH regulator device in the pH regulator groove, be provided with the PAC chemicals dosing plant on pH regulator groove top and add the alkali medicine-chest.Be provided with the acid adding medicine-chest between lift pump and char filter, be provided with the Scale inhibitors chemicals dosing plant between char filter and secondary filter.
The utility model can by in microfiltration membrane device trap water greater than the suspended substance of 0.1us, and can see through less than the suspended substance of 0.1us, the organism that the micro-filtration water outlet is removed in water through char filter directly can be used as by secondary filter the pre-treatment that online recycling and middle water reuse enter reverse osmosis, thereby traditional settling tank, quartz filter and ultra-fine filter have been replaced, the technique that reclaims for heavy metal simultaneously, microfiltration membrane can reclaim 99.9% heavy metal, is to reclaim heavy metal well to select in heavy metal-containing waste water.
The beneficial effects of the utility model are: the utility model adopts the tube type filter membrance method to process reuse waste water and reclaims the metal ions such as copper in waste water, nickel, has the ability of filtering particle contamination material and can not divulge the phenomenon of mud particle; Microfiltration membrane can be born the cleaning of acidity, alkalescence, bleaching and oxidation medicament; The film pipe of microfiltration membrane has durable quality, and comparing with general filtering material has the long usage period.The utility model is compared traditional chemical precipitation processing and is added middle water reuse, and perhaps micro-filtration adds reverse osmosis process, and flow process is simpler, operates convenient, easily realizes automatization control; It is little that the micro-filtration embrane method is compared traditional chemical precipitation floor space, can save the investment of capital construction phase, drop into but also can save medicament, because chemical precipitation need to all add flocculation agent in order to guarantee sedimentation effect, increased virtually medicament and dropped into to get expense, and added too much medicament and also can exert an influence to subsequent processing device.
The utility model can improve the efficient of sludge press filtration, traditional chemical precipitation is regularly settling tank to be carried out spoil disposal, inevitably can increase the water ratio of mud in the spoil disposal process, and microfiltration membrane is by constantly concentrating containing heavy metal muddy water, be concentrated to and to a certain degree be discharged to again sludge thickener, so just can reduce the water ratio of mud, improve efficiency of press filtering.The utlity model has the effluent index of almost Perfect, the sewage quality index pollution index SDI of system's water outlet is between 2～4, satisfies the requirement of feed water by reverse osmosis fully; Simple to operate, can realize unmanned, thereby reduce the employment cost.
