Beneficial effect: middle-size and small-size sewage disposal integrated purifying device provided by the invention has the features such as compact construction, floor space is little, easy to use, flexible operation, processing cost are low, effluent quality is high, suitability is strong, has good popularizing application prospect.
Specifically, the present invention completes the disposable automatic back flow of mud, mixed solution by the water flow impact pressure of inhalant region, and the nitrification liquid of backflow can promote that oxygen-starved area, bottom realizes biological denitrification denitrification process, and achieves inversion A
2the basic usefulness of O technique.
Precipitation is core of the present invention with the form that arranges of sludge reflux unit.The high efficiency separation of water, mud is achieved by the setting of baffle plate.In sepn process, water and flco are according to diverse orbiting motion, thus avoid the mutual interference effect of the current existing for traditional sludge separate mode and mud flco, ensure that the separating effect of mud, and the optimization of reflux unit setting position further promotes sedimentation and the separation of mud; In addition because mud automatically can be collected, reflux, thus reduce the setting of the equipment such as traditional suction dredger, mud scraper, while minimizing construction costs, reduce running maintenance work.The further contact probability of whipping appts efficient hardening mud and water can be passed through in the stirring area that rear portion, aerobic reactor zone is arranged, and guarantees sludge absorption effect.
Arranging of photochemical catalytic oxidation unit on the one hand can organic molecular structure in reinforced deposition water outlet, also can strengthen the oxidation effectiveness of micro quantity organic pollutant on the other hand, thus is conducive to the removal of subsequent technique to organism and micro quantity organic pollutant.
The set-up mode of photochemical catalytic oxidation unit ensure that the current thickness on baffle plate, and effectively avoids, due to too high the caused suction function of weir loading, being conducive to the control of delivery turbidity and being separated of flco.
This device utilizes bottom space to arrange disinfection unit, the effect of clean water basin of can having held concurrently, back flushing water tank, thus achieves Highgrade integration, intensive, and floor space significantly reduces, and general floor space can reduce more than 50%.
This device discharges waste water and backwashing wastewater only just need can realize effective mud-water separation through of short duration quiet sinking after collecting, and supernatant liquor can be back to water inlet pipe, reduces the generation of waste water.
This middle-size and small-size sewage disposal integrated purifying device itself has taken into full account that water (flow) direction and each processing unit are to the requirement of head, greatly improve effective utilization of the potential energy of water, and the discharge of unnecessary flco is also discharged by free gravity in operational process, thus decrease the loss of energy, be conducive to reducing running cost.
This device is considered mainly for middle-size and small-size Sewage Plant construction, but combinationally uses for Large Water Works construction by the fine setting of correlation parameter and the number of device.
