Description
Technical field
The invention belongs to Industrial Waste Water Treatments field, be specifically related to a kind of device processing difficult for biological degradation pollutent.
Background technology
Circulatior clarifier utilizes body refuse in pond and flocculation agent, and the impurity particle in former water contacts with each other, adsorbs, and to reach the purification structure of mud-water separation, it is high that it has throughput, high treating effect.
In circulatior clarifier, heavy mud is lifted up and makes it to be in equally distributed suspended state, forms the stabilizing active slime layer of high density in pond.Former water flows from bottom to top in settling pond, and slime layer can be in dynamic balance state due to action of gravity in ascending current.When former water is by activated sludge layer, utilize contact flocculation principle, the suspended substance in former water is just got off by the detention of active sludge slag blanket, makes water obtain clarification.Clear water is collected on settling pond top.
But in practice, there is following problem in this traditional circulatior clarifier:
(1) sludge backflow amount is difficult to control---and circulatior clarifier is in operational process, spoil disposal is Artificial Control, because artificial factor often causes active sludge not enough, or old body refuse is superfluous, make waterpower skewness, lose original balance, formed outside bad waterpower follows, both waste manpower and materials, in turn increase Maintenance and Repair expense;
(2) reaction chamber volume is less, and the reaction times is shorter, and the performance of backflow body refuse contact flocculation effect is affected, and the flco of generation is loose, light specific gravity, and hybrid reaction and decontamination effect improving are relatively poor, thus causes reagent consumption larger;
(3), when in raw water turbidity low or short period of time, the water yield, water quality and water temperature change greatly, operating performance is stable not, and adaptability is poor, inhibits the performance of Hydraulic Circulation function to a certain extent;
(4) nozzle, trunnion place resistance are comparatively large, and cause head loss to increase, energy expenditure is corresponding larger;
Recalcitrant substance be often referred to natural condition be difficult to by biological action fall progressively decompose organic chemicals, also difficult degradation oil, difficult degradation SS (in water quality suspended substance) etc. is comprised, recalcitrant substance persistence in the environment, and the dispersiveness of wide area, environment and ecology is impacted larger, therefore, be environmental pollution always, make the important step of benign circulation of the eco-environment.
At present, biological process, physico-chemical process and oxidation style etc. are mainly contained to the treatment process of hardly degraded organic substance waste water both at home and abroad.Biological process mainly comprises active sludge, biomembrance process, Aerobic-anaerobic method etc.; Physico-chemical process mainly contains absorption method, extraction process, various membrane technologies etc.
Emulsifiable oil waste water is because wherein making oil become emulsion containing tensio-active agent, oil droplet size is atomic little, kinetically there iing stronger stability, and organic content is very high in emulsion, usually more difficult, adopt the combination of the methods such as oil removal, air supporting, coagulation to process in common engineering, but the COD of water outlet is still very high, emission request can not be met, or multiple-stage treatment causes complex process, long flow path, cost high, the problems such as effluent quality is unstable.
Containing suspended substance that is more tiny or lighter weight in some trade effluents, difficulty is retained by grid, is also difficult to remove by the precipitator method.
In prior art, the method for removal hardly degraded organic substance waste water, emulsified oil-containing waste water, difficult suspended wastewater is effective, but auxiliary facility is many, floor space is large, initial cost is large, working cost is high, and energy consumption is large.Therefore, look for a kind of flow process simple, above-mentioned shortcoming can be overcome, the method for removal hard-degraded substance that treatment effect is good is problem anxious to be resolved in sewage treatment area.

Flocculant solution adds concentration: 1 ~ 3ppm;
Prestowage agent solution adds volume: 10% ~ 20% of retort useful volume.
(2) eddy flow is mixed:
Open valve V
1open external pump 9, by three dosing mouths of line mixer 10 respectively to passing into three kinds of liquid medicines in line mixer 10, pass into tap water to water inlet pipe 15 simultaneously, reactor tank body 1 is entered by water-in 7 with tangential direction jet after medicament mixes in line mixer 10 with water, bottom reactor tank body 1, form quick eddy flow, stop water inlet, valve-off V when reactor tank body 1 inner fluid liquid level arrives water outlet 2 position
1, Open valve V
2and V
3;
The quick eddy flow fluidised form of reactor tank body 1 bottom flow makes mixed solution fully mix and react, and hybrid reaction formed tiny flocculent substance after 10 ~ 20 minutes;
Owing to being subject to the guide functions of reactor tank body 1 interior shape and shore pipe 6, fluid rises along reactor tank body 1 inwall eddy flow.
(3) stable suspersion:
In the process that fluid eddy flow rises, tiny agglutinating matter cohesion forms larger agglutinating matter, and flow velocity slowly declines, these agglutinating matters accumulate formation suspended layer gradually, this suspended layer is slowly upwards passed also constantly closely knit, in reactor tank body 1, concentrated deslagging chamber 5 position forms stable suspersion layer, has certain thickness and degree of compactness, and formative dynamics eddy flow equilibrium state;
Whether observe stable suspersion layer by visor 11 to be formed, stable suspersion layer forms needs 5 ~ 24 hours.After stable suspersion layer is formed, continue to add prestowage agent solution in line mixer 10, adding rear prestowage agent concentration is 10 ~ 30ppm.
(4) Filtration Adsorption:
Stable suspersion layer is formed and namely represents reactor start-up success, Open valve V
1and V
4, according under meter 14 regulated valve V
2make backflow ratio 50% ~ 100%, pending waste water is passed into from water inlet pipe 15, waste water is through external pump 9 and line mixer 10, enter bottom reactor tank body 1 by water-in 7 with tangential direction jet again, when recalcitrant substance in waste water from bottom to top eddy flow through stable suspersion layer, agglutinating matter in stable suspersion layer can filter and adsorb refractory organic, fine suspension and the emulsification wet goods material in these waste water, reaches good water treatment effect;
Clean water processed while waste water continuum micromeehanics is discharged from water outlet 2 by effluent weir 3.
(5) body refuse is discharged:
On stable suspersion layer, interface is uncovered near the upper end of concentrated deslagging chamber 5, flocculent substance constantly adds to the bottom of suspended layer from bottom to top, stable suspersion layer is constantly thickened, because stable suspersion layer is running balance, so suspended layer is while purifying liquid waste, the mud that its top is comparatively aging, Filtration Adsorption ability reduces can be pushed, and by shore pipe 6 discharges mud in dropping concentrated deslagging chamber 5 along the uncovered edge, upper end of concentrated deslagging chamber 5.
