Description
Technical field
The present invention relates to a kind of waste disposal plant, particularly a kind of film coagulum reactor (MAR).
Background technology
Traditional urban sewage treatment process generally adopts preliminary sedimentation tank as pretreatment system, to remove suspended substance in sewage and particulate matter, improve the biodegradability of sewage and reduce the organic loading of subsequent treatment process, but preliminary sedimentation tank mainly carries out pre-treatment by physical action to sewage, need the gravity natural sedimentation of long period, the upper strata sewage after precipitation flows into subsequent processing units through weir notch.But suspended substance equal size is unstable in water, comparatively large on subsequent disposal impact, floor space comparatively simultaneously, serious waste land resources.
In traditional industry sewage disposal, after the techniques such as coagulation-flocculation air supporting, before entering membranous system, after sewage needed settling tank to precipitate, then through the filtration such as quartz filter, manganese sand filter, removed in water and entered follow-up system after suspended substance.But still difficulty controls suspension content and its stability in water, its facility investment is large, and floor space is relatively also larger, waste of manpower financial resources.
As can be seen here, the difficult problem that the content going out water suspension and stability, floor space are current technology is solved in pretreatment technology.Through retrieval, also do not find that any employing membrane filtration form carries out the method for coagulation.
Summary of the invention
The object of this invention is to provide a kind of film coagulum reactor, mainly solve the uncertainty of existing sewage coagulation device effluent quality (suspended substance) and the technical problem such as floor space is large.Reactor of the present invention not only can ensure that effluent quality (suspended substance) reaches requirements at the higher level, and can also reduce floor space efficiently, shortens treatment scheme, reduces the coagulation time, can also ensure the smooth and easy operation of follow-up system.
Technical scheme of the present invention: a kind of film coagulum reactor, comprises service pump, mud level meter, pump sump, electronic spoil disposal slag-drip opening, membrane module, goes out water pump, water flow meter, backwashing pump, clean water basin, programmable logic controller.Described service pump is arranged on pump sump front end, is connected by pipeline.Described mud level meter is arranged on above pump sump.Be provided with membrane module in pump sump, pump sump lower end is provided with electronic spoil disposal slag-drip opening, and membrane module is connected by pipeline with the water pump that goes out being arranged on pump sump rear end, goes out water pump and is provided with water flow meter.Clean water basin are arranged on out water pump side, install backwashing pump in described clean water basin, and backwashing pump is by pipeline junctional membrane assembly.Described programmable logic controller respectively with service pump, mud level meter, electronic spoil disposal slag-drip opening, go out water pump, backwashing pump is connected.
Described membrane module is ultra-filtration membrane, selects the one in hollow-fibre membrane, tubular membrane or flat sheet membrane; It is taper scarp bottom pump sump.
Advantageous Effects of the present invention:
(1), effluent quality is good and stable (ss≤5mg/L, turbidity≤0.5NTU), can directly enter subordinate's treatment system;
(2), efficiently solid-liquid separation is carried out, the treatment time short (directly passing through water pump to extract, without the need to sedimentation time);
(3), treatment unit floor space little (the wide * of long * is high: 1m*0.8m*1.5m);
(4), (4 groups of membrane modules, specification is treatment unit filtration area: 0.53m*0.4m*1.01m, and each membrane module effective filtration area is 10 ㎡ greatly.)；
(5), installation cost low (price aggregate is about 100,000 yuan);
(6), level of automation is high, convenient operation and management;
(7), in-site installation and convenient transportation.
