A deep wastewater treatment system adopts an aeration biologic filtering tank method, and a reclaimed water treatment system adopts combination of ceramic particle filtration and ultrafiltration deep treatment units, so that the quality of effluent of the wastewater treatment system is effectively improved, and the reuse rate of the reclaimed water is improved.
Description
Technical field
The present invention relates to yarn dyeing field, be specifically related to a kind of dyeing waste water advanced treatment intermediate water reuse system.
Background technology
Dyeing waste water belongs to manage compared with refractory in trade effluent a kind of.Due to technology, economic dispatch reason, biology-physics improvement method that most adopts can only reach basic emission request.Although slightly decline in colourity, organic substance is just resolved into less material, these degradation production character are difficult to control also very difficult grasp, cannot guarantee environment not produce harm.Therefore how to solve waste water advanced processing and middle water reuse, lifting waste water treatment system effluent quality, in raising, the problem of reusing rate seems particularly important.
Summary of the invention
For existing deficiency, the object of this invention is to provide a kind of dyeing waste water advanced treatment intermediate water reuse system, advanced waste treatment system has adopted Gas biological filter, reuse water treatment system has adopted ceramic filtration+hyperfiltration advanced processing unit combination, effective lifting waste water treatment system effluent quality, reusing rate in raising.
The object of this invention is to provide a kind of dyeing waste water advanced treatment intermediate water reuse system, comprise air flotation pool, the water side pipeline of air flotation pool is connected in the feed-water end of intermediate pool I, the feed-water end that is connected in BAF by lift pump pipeline is established in the water side of intermediate pool I, the water side of BAF is connected in the feed-water end of intermediate pool II, the water side of intermediate pool II is connected in the upper end feed-water end of ceramic filtration device by lift pump pipeline, the water side pipeline that is positioned at ceramic filtration device bottom is connected in the feed-water end of ultrafiltration apparatus, the water side pipeline of ultrafiltration apparatus is connected in clean water basin, the water side of clean water basin is connected with ion exchange system, the water side of ion exchange system is connected in rising pipe.
Further improvement of the present invention is: in described BAF, be provided with intake stack, be provided with blower fan on intake stack.
Further improvement of the present invention is: water side one side of described BAF, ceramic filtration device, ultrafiltration apparatus is provided with back flushing port, on back flushing port, is provided with backwashing pump.
The waste water of recovery after sewage treatment equipment is processed flows into intermediate pool I from air flotation pool, by lift pump, carry into BAF and further carry out biochemical treatment again, BAF can reduce the residual COD in water effectively, integrate bio-oxidation and hold back suspended solids, saved post precipitation pond (second pond), there is volumetric loading, hydraulic load is large, hydraulic detention time is short, required initial cost is few, effluent quality is good, operation energy consumption is low, the water of the few feature of working cost after BAF is processed flows into intermediate pool II, there is again lift pump to pump into ceramic filtration device and carry out depth type filtration, the main suspended substance of removing in water, can effectively prevent and treat corrosion material in suspended substance residual in pre-treating technology and pipeline, guarantee that influent quality meets the requirement of ultrafiltration system.Prevent that suspended substance from stopping up ultrafiltration fenestra, extends the work-ing life of ultra-filtration membrane.Waste water dependence overbottom pressure enters ultrafiltration apparatus and carries out membrane sepn, and for the particle of trap water colloid size, without heating, energy consumption is low, without adding chemical reagent, pollution-free; It is standby that waste water after membrane sepn enters original clean water basin, then the line that can put into production after original ion exchange system is processed is used.
Beneficial effect of the present invention: advanced waste treatment system has adopted Gas biological filter, reuse water treatment system has adopted the combination of ceramic filtration+hyperfiltration advanced processing unit, effective lifting waste water treatment system effluent quality, reusing rate in raising.
