Description

For automatically processing the integration apparatus of sewage
Technical field
The utility model is related to technical field of sewage and in particular to being used for automatically processing the integration apparatus of sewage.
Background technology
At present, the environmental protection pressure of the shortage of water resource and blowdown, governs the development of China's economic society.Therefore, each work Industry enterprise, municipal sewage plant etc. are numerous and confused to be attempted proceeding by advanced treatment of wastewater and Treated sewage reusing, to realize sewage recycling profit With, more preferable environmental protection, solve water problems.For Treated sewage reusing, the basic basis of consideration first are the uses of reuse Place.Industrial enterprise is included with water occasion: recirculated cooling water, boiler water, process water, flushing water etc..Municipal water use is mainly wrapped Include: drinking water, greening water, landscape water etc..These typically all comprise two main, comprehensive fingers with water water standard Mark: turbidity/suspended solid (ss), salt content (tds).
It is divided into two steps: 1) turbidity removal, removal suspended particulate: ultrafiltration using the process that embrane method technology of middle water recycle mainly includes Film, microfiltration membranes, by biological floe remaining for sewage disposal,
Mushroom etc. retains, and uses clarification of water, can reach reuse or further treatment for reuse.Membrane technology bag for turbidity removal Include: hollow fiber ultrafiltration membrane, membrane bioreactor (mbr) etc..2) desalination: reverse osmosis membrane ro or nanofiltration nf, by going out of clarification Water carries out film desalination, is divided into two bursts of concentrated waters (discharge) and fresh water (reuse).
Advanced treating to general biochemistry secondary clarifier effluent, the most frequently used process step is exactly to filter, and makes secondary clarifier effluent Biological floe and colloidal substance can be trapped in above filtrate, reduce the ss of water outlet and turbidity.Advanced treating to waste water, warp Filter frequently with sand filtration and activated carbon.Sand filtration as be mainly used in remove ss, colloidal substance, and activated carbon may filter that absorption organic Thing, heavy metal classes, oxidizing substance.There is fluctuation during for water outlet ss, longtime running can be stablized for ensureing to filter, water inlet can be increased If measures such as coagulating sedimentation, to extend the recoil cycle of filter.Through filtration water outlet ss can be reduced to < 5mg/l, absolutely mostly The big particle diameter colloidal solid of number also can remove, but to less than 0.1um particles below, still part exists.Therefore, it is necessary to Carry out pre-filtering to before ro film.The filtration particle diameter of hollow-fibre membrane ultrafiltration is 0.01um to 0.2um, passes through doughnut in principle The delivery turbidity of film ultrafiltration is 0, and the bacterium in trap water simultaneously prevents the germ contamination of rear class film.And the rate of recovery of system is high, More than 90% can be reached.Therefore hollow-fibre membrane ultrafiltration, is a good pretreatment.

1st, gravitational separation process, to the clearance of suspended things, oil slick and dispersed oil more than 60%, treatment effect is stable, running cost With low, treating capacity is big, but system footprint area is big, and the sedimentation time is long.
2nd, centrifugal separation, to the clearance of suspended things, oil slick and dispersed oil more than 60%, process time is short, and effect Good, but operating cost is high, and energy consumption is big.
3rd, filtration method, to the clearance of suspended things, dispersed oil and oil emulsion more than 10%, water quality is good, and equipment investment is few, no Scum silica frost;It is big that filter bed will rinse water consumption repeatedly.
4th, absorption method, to suspended things, dissolved oil clearance 10% about, water quality is good, and equipment takes up an area few;But equipment is thrown Money is high, and adsorbent reactivation is difficult.
5th, Bubble-floating Method, is more than 10% to the clearance of suspended things, oil emulsion and dispersed oil, effect is good, technical maturity.
6th, coagulant sedimentation, is more than 10% to the clearance of suspended things, oil emulsion, high treating effect;But take up an area big, medicament Consumption is big, and mud is difficult.
