Abstract
The invention discloses a defoaming method of coal chemical-industrial wastewater. According to the defoaming method, defoaming water is extracted from a secondary sedimentation tank of a biochemical pool by virtue of a defoaming water pressure pump, is filtered through a Y-shaped filter and is conveyed to each defoaming nozzle, and atomized defoaming water is sprayed into the biochemical pool by each defoaming nozzle, thereby realizing the defoaming in the biochemical pool; the defoaming capacity is relatively high, and fresh water does not need to be collected, so that the water resource is greatly saved, and the integral water yield load is not increased; meanwhile, by forming an access hole, the daily maintenance is facilitated.
Description
Technical field
The present invention relates to Coal Chemical Industry phenolic wastewater aerobic treatment method field, specifically a kind of coal chemical industrial waste water debubbling method.
Background technology
In Coal Chemical Industry phenol ammonia waste water or Treatment of Coking Effluent project, due to containing a large amount of phenolic wastewater, it can produce a large amount of foams when aerobic biochemical, froth breaking generally adopts defoamer or water smoke froth breaking, adopt defoamer cost higher, can secondary pollution be brought, increase sewage treatment load.Adopt water smoke froth breaking then can consume large water gaging, adopt fresh water can cause consumption great lot of water resources, the water of biochemical treatment system inside is adopted to carry out froth breaking, great lot of water resources can be saved, water froth breaking is then that water is sprayed into water smoke, destroy by the surface tension of band pressure water smoke to foam, thus obtain froth breaking object.
The water of biochemical treatment system, is still having a large amount of suspended substance, mud and some other impurity after settling tank precipitation, for can blocking pipe and shower nozzle during froth breaking.In northern cold cold wind sand ground territory, biochemistry pool often needs to add a cover, and cannot overhaul when shower nozzle blocks, and brings much run difficulty to engineering.
summary of the inventionthe object of this invention is to provide a kind of coal chemical industrial waste water debubbling method, to solve prior art biochemistry pool froth breaking Problems existing.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of coal chemical industrial waste water debubbling method, it is characterized in that: using the secondary sedimentation basins water outlet of biochemistry pool as froth breaking water, in biochemistry pool top glass steel cage, both sides arrange multiple froth breaking shower nozzle respectively, both sides froth breaking shower nozzle equal altitudes and respectively with 45 ° of inclination angles towards in biochemistry pool, adopt froth breaking water force (forcing) pump, y-type filter, froth breaking water force (forcing) pump water-in is communicated with the water outlet of secondary sedimentation basins, the water outlet of froth breaking water force (forcing) pump is communicated with y-type filter water-in, is communicated with respectively by each froth breaking shower nozzle each via trip valve with the water outlet of y-type filter; Draw froth breaking water by froth breaking water force (forcing) pump from the secondary sedimentation basins of biochemistry pool, and in froth breaking water is sent into each froth breaking shower nozzle after y-type filter filters, in biochemistry pool, spray vaporific froth breaking water by each froth breaking shower nozzle, realize froth breaking in biochemistry pool.
Described a kind of coal chemical industrial waste water debubbling method, is characterized in that: y-type filter filters the medium-and-large-sized floating matter of froth breaking water, alleviates the blocking to pipeline and shower nozzle, is regularly cleared up by the impurity of y-type filter, avoid y-type filter to block.
Described a kind of coal chemical industrial waste water debubbling method, is characterized in that: the trip valve of regularly closed portion froth breaking shower nozzle connection, makes the water yield of residue froth breaking shower nozzle increase, and pressure raises simultaneously, to wash away remaining froth breaking shower nozzle, alleviates blocking.
Described a kind of coal chemical industrial waste water debubbling method, it is characterized in that: in glass fibre reinforced plastic cover, the position of each froth breaking shower nozzle corresponding arranges the access hole that diameter is not less than 300mm respectively, access hole place adopts glass fiber reinforced plastic flange lid to cover, and easy access, avoids foam excessive from access hole simultaneously.
Described a kind of coal chemical industrial waste water debubbling method, is characterized in that: froth breaking shower nozzle adopts conical hollow spiral spray nozzle, because shower nozzle is hollow, then alleviates blocked, and cone-type spiral is the prerequisite forming water smoke simultaneously.
The present invention using water outlet in biochemistry pool secondary sedimentation basins as froth breaking water, and as biochemistry pool froth breaking water after being filtered by y-type filter, has good defoaming capacity, and need not adopt fresh water, has greatly saved water resources, can not increase overall water yield load.Be that maintenance repair is provided convenience by arranging access hole simultaneously.
