Advanced water treatment reclaimed water reuse technology during the present invention is full-automatic, it is characterized in that: flow process is as follows:
(1), uf processing
After pending water filters through sandfiltration pot, entering the biochemical water film filtering device of malleation filters, enter the ozonizer sterilizing and purifying then, then, water after will being handled by water pump pumps into aeration tank, after being subjected to uviolizing and aeration simultaneously, inject adsorption tanks, through the ultrafiltration water receptacle that reinjects of the water after the absorption;
(2), nanofiltration is handled
By high-pressure pump the extraction of the water in the ultrafiltration water receptacle is forced into 0.8～1.35Mpa and injects the nanofiltration assembly, carry out ion level and filter, the water purification of output is stored in the nanofiltration water receptacle and treats reuse, and the dense water of output returns the ultrafiltration water receptacle and handles once more;
(3), backwashing manner
Open the water distributor wash-down water import of the biochemical water film filtering device of malleation, add pressure water, after the flushing of hollow external pressure hyperfiltration membrane assembly, open the pressure sensing valve sewage is entered biochemistry pool.
The water supply positive pressure of the biochemical water film filtering device of above-mentioned malleation is 1.5-6kg.
Beneficial effect: in full-automatic advanced water treatment reclaimed water reuse device and process using the biochemical water film filtering device of malleation, filter membrane component curtain formula is arranged that changing disc type into arranges, filter membrane component is selected hollow external pressure hyperfiltration membrane assembly, be placed in the sealed can, the tubular type water distributor is arranged in the tank body, by water-aspirator pressure second pond water after irritating filtration, is injected tank body in sand filtration, after hollow external pressure hyperfiltration membrane assembly filters, drain in the water purifying chamber of tank body by the inner core outlet, import the ozonizer sterilization again, purify, behind the water pump chlorination, pump into aeration tank again, shone by ultraviolet radiation device, catalysis, and behind the aeration, through adsorption tanks absorption detrimental impurity, then can enter the ultrafiltration water receptacle again.The sewage supernatant liquor of second pond, after this process was filtered, water quality can reach the reuse water service requirements.After water in the ultrafiltration water receptacle was pumped into the nanofiltration assembly and filtered once more by high-pressure pump, its reverse osmosis-purified water entered the nanofiltration water receptacle, can reach standard for drinking; Reverse osmosis concentrated water drains back to the ultrafiltration water receptacle again.
When the biochemical water film filtering device of malleation need wash, the utility model is a positive pressure wash, need not back flushing, when timer sends flush signal, automatically close with the timer switch valve that tank body top water outlet is connected, wash-down water laterally is responsible for from water distributor and is entered, make supercharging in the biochemical water film filtering device of the malleation tank body, when pressure tank reaches 3-5 kilogram/cm2, the pressure transmitter command pressure sensing valve (heavy caliber) of tank base is opened, water is discharged at a high speed from arranging concentrated water spout under pressure in jar, this moment, a jar interior hollow malleation ultrafiltration moisture film assembly formed pencil under flow action, and was rinsed totally, because row's concentrated water spout footpath is greater than one times of water-in, when the jar internal pressure is lower than 0.5kg, below pressure sensing valve locking.
The present invention adopts the technology of positive press filtration, positive pressure wash, and is simple in structure, easy to operate, the purification efficiency height, and the water treatment comprehensive cost reduces, and filter membrane prolongs work-ing life.Solved membrane bioreactor work-ing life short, antifouling property is relatively poor, purification efficiency is low, the problem of readily biodegradable.Can be used for the municipal water use, the construction project water, irrigation water, landscape water and car washing water are if connecting tube advances building and can do flushing supply; If after connection nanofiltration purifier purified again, water quality reached drinking water standard.In the pollution-free and low region of hardness, can not add the biological bacteria direct filtration, substitute traditional tap water water preparation process, save a large amount of soils and flocculation medicament, guarantee water quality, reduce water producing cost.
The present invention can implement purifying treatment at the various former water that pollute in various degree; The application of multiple sensing technology and little electric automatic control pipeline valve makes this system realize real full automatic control; The present invention has reduced by 40% floor space than conventional processes, saves cost 40%, solved film bioreactor device work-ing life short, antifouling property is relatively poor, purification efficiency is low, the problem of readily biodegradable.Use the present invention, can save great lot of water resources.Water is repeatedly reused, and water saving reaches 50%～65%, and comparatively speaking, comparable biochemical treatment is again saved and taken up an area of 60%, reduces civil engineering, can remove colloid effectively, macromolecular cpd, thermal source and microorganism etc.; SS can all remove, and COD clearance 65%～75%, BOD are 60%～80%, and LAS is 40%～60%, and bacterium and coliform are 99.99%; Final stage disposes the nanofiltration assembly that I produce, and the COD clearance is 99.2%, and BOD is 99.5%, 100% removal bacterium and coliform and the above material of divalence; Total ratio of desalinization is 85%～95%, and each pollutant of filtering makes processing back water quality reach the higher level reuse standard fully.
