Embodiment
Below by accompanying drawing 1, accompanying drawing 2 and embodiment, the present invention is further elaborated.
Embodiment：
Case history investigation is processed by existing Treated sewage reusing, the problems such as most of milipore filter all occurs in that fracture of wire, blocking, life-span end is found；Find again simultaneously, as milipore filter fracture of wire caused the lost of life of reverse osmosis membrane core to 3 to 6 months, cause maintenance to be invested big, operating cost is high.In this regard, the present invention proposes a kind of Treated sewage reusing handling process, can solve the problems, such as that ultrafiltration brings, can reduce after enforcement floor space, simple to operate, increase the service life, meanwhile, construction investment is saved, and operating cost is low.By taking certain printing and dyeing mill as an example, existing pretreatment scale 2000t/d, COD concentration 198mg/L, pH 7.5 of wherein middle water such as will return to plant process water to the present embodiment, need to carry out advanced treating, it is desirable to which water outlet reaches《Industrial reuse water water standard》, produce water efficiency and reach 65%, and direct reuse is in Workshop Production water.Specific embodiment is as follows：
The middle water of existing pretreatment is entered tank 1 first, carry out storing homogeneous, lifted with circulating pump 2 and send into the built-in tube core of periosteum device 2, by the molecule in water less than film core bore footpath 0.1um and solubility salt, flow out through film core from drain pipe 2-2, insoluble macromolecular and particulate matter is therefrom removed, is flowed out from dope pipe 2-1 after being mixed together with concentrated water, then is back to tank 1 and is mixed.
Second, air pump 4 is configured with to periosteum device 2, allows the air of 4 output of air pump, be conveyed to periosteum device 2 through air hose 4-1, washed away film core by phased manner with air, to prevent the blocking of film core micropore；Meanwhile, return air pump and be provided with time control, it is desirable to every 5 minutes～10 minutes to the qi of chong channel ascending adversely of film core once, qi of chong channel ascending adversely perdurabgility is every time 30 seconds～60 seconds.After enforcement, the effect for processing water is substantially increased, the service life of tube core is extended.
3rd, the water that 2 outlet pipe 2-2 of periosteum is flowed out enters the filter core 5-1 of cartridge filter 5, filter the minute solid particles thing being trapped in water, the pollution index SDI ＜ 5 in water is made, this index is reached, clean outlet degree is further improved, be conducive to the process load for mitigating lower one reverse osmosis membrane apparatus 7, the water quality for producing water is improve, the service life of film is extended, is alleviated maintenance cost.
4th, water just in cartridge filter 5 is sent into membrane tube 7-1 of reverse osmosis membrane apparatus 7 by high-pressure pump 6, under the pressure of 1.5MPa or so, the material such as hydrone and very small amount monovalent ion is through the film core in membrane tube, discharge from water producing pipe 7-3, the clean water of output is back to industrial water, and cannot pass through the solid particle and the macromolecular substances such as monovalence and above ion of the retention filtration of membrane tube inner membrance core and discharged from concentrated water pipe 7-2, be then refluxed for middle water pretreatment system.
Implementation result：A kind of Treated sewage reusing handling process, middle water of the preprocessed COD concentration less than 200mg/L, pH6.5～9, by implementing, three-level optimum organization process of the water through periosteum device, cartridge filter, reverse osmosis membrane apparatus in realizing, producing water water quality reach《Industrial reuse water water standard》, in production technology water, product water efficiency meets production needs up to more than 65% to energy direct reuse.The present invention passes through optimum organization, innovative design, more brief than traditional Treated sewage reusing technological process, reduce advanced treatment unit, it is avoided that the series of problems that milipore filter fracture of wire is caused, the service life of reverse osmosis membrane is extended, little with floor space, construction investment is saved, equipment is easily fabricated, installation and debugging are convenient, manage the advantages of simple to operate and operating cost is low, energy-conservation is lowered consumption again, therefore, implementation result of the present invention is good, there is certain creativeness, the Treated sewage reusing for going for every profession and trade is processed, and application prospect is big.
