sewage PH value and N/P ratio and the temperature of regulating of equalizing tank, carry out homogeneous and all measure, make its applicable subsequent technique requirement, improve water treatment effect.The Demulsification and coagulant air supporting deslagging device arranging, can lean on removing dross groove to collect scum silica frost outer row in the mode of overflow, has guaranteed effectively carrying out of subsequent technique.Specifically, described Demulsification and coagulant air supporting deslagging device, can the chain link by rectangle drive scraper plate that the fluid of surface, oil partiting precipitation pool pond is scraped toward the oil trap on oil removal wall, outer row again, garbage, waste-water enters into the water side water outlet of oil removal wall rear from the hydrospace of crossing between at the bottom of oil removal wall lower end and oil partiting precipitation pool pond.Therefore the food and drink class scum silica frost such as the fluid of removal garbage, waste-water that can quickness and high efficiency the inside and capsicum Chinese prickly ash, and have simple in structurely, control advantage easily.Chain link, in frizing, can scrape the precipitating sludge at the bottom of oil partiting precipitation pool pond in mud-collecting slot, and arrange outward by mud discharging pipeline, reduces follow-up waste water silt content, adopts the more functional effect of simple structure generation.Also be provided with drainage wall and change water inlet direction, make to walk around drainage wall into can first flowing downward after water enters oil partiting precipitation pool, allow the throw out in garbage, waste-water be deposited to better in mud-collecting slot, produce sedimentation effect better, and waste water is walked around after drainage wall fluid floating automatically, can not affect frizing effect.In native system, be also provided with the apparatus for controlling water exit temperature of external circulating system, extracting the garbage, waste-water of equalizing tank exit end out equalizing tank makes it after cooling tower and electrothermal module, get back to equalizing tank exit end outward, by temp probe, detect water exit position water temperature, then opening as required cooling tower cooling or electrothermal module heats, the water temperature of strict guarantee water outlet is the required water temperature requirement of subsequent technique, the processing of need to lowering the temperature general summer, need heat treatment winter, guarantee that water temperature is controlled at 40 ℃ of left and right, guarantee subsequent technique treatment effect.This apparatus for controlling water exit temperature also has simple in structure, convenient enforcement, temperature adjusting efficiency advantages of higher.In native system, be also provided with emergent equalizing tank, emergent equalizing tank and equalizing tank, all according to 1248 cubic metres of left and right capacity setting, guarantee that water quality stops 24 hours, to play good homogenizing effect.Like this, arrange after emergent equalizing tank, when flooding quantity larger, when equalizing tank has little time to process, water inlet can be imported in emergent equalizing tank and regulate, then when flooding quantity hour, can lean on equalizing tank to supply water to subsequent technique, therefore emergent equalizing tank can play the effect of emergent regulation and control, guarantee the continuity that subsequent technique is processed, can play better homogeneous and all measure regulating effect.When Demulsification and coagulant air supporting deslagging device is used, sewage is introduced into emulsion splitter interpolation chamber, and this chamber is used for adding emulsion splitter and by whipping appts stirring reaction, further destroys emulsification fluid composition in garbage leachate, the materials such as fluid that its disperse phase cohesion is separated out.Then sewage enters into PAC/PAM interpolation chamber, this chamber is used for adding PAC/PAM(polymer alumina coagulating agent and non-ionic type polymeric flocculant) and by whipping appts stirring reaction, wherein the polymerization of PAC coagulating agent makes sewage degraded precipitation, PAM flocculation agent can adsorb and flocculate with the suspended particles bridge formation being scattered in sewage, both mixing effects, make to be difficult in a large number be generated a small amount of precipitation and a large amount of scum silica frost by the material of follow-up sewage disposal in sewage, then enter into Demulsification and coagulant air supporting deslagging device main body inner chamber, scum silica frost can be collected by removing dross groove and outer row, like this, this Demulsification and coagulant air supporting deslagging device can be removed the less suspended substance of proportion in waste water efficiently, fluid, part COD is with colourity, guarantee follow-up wastewater treatment efficiency.The inclined-plane trench structure that accommodating body main body intracavity bottom arranges, can guide the scum silica frost of generation to rise to liquid level better, and then by removing dross groove, is collected outer row better, improves scum silica frost removal effect.Arrange every mud plate and poly-mud groove, can be better every mud, poly-mud outer row, make the mud precipitating in Demulsification and coagulant air supporting deslagging device can not follow water outlet outer row to affect subsequent technique treatment effect together, improved the desilt effect of Demulsification and coagulant air supporting deslagging device.
During concrete enforcement, above-mentioned preprocessing system, for realizing the waste water pre-treatment of changing food waste, after pre-treatment, the waste water of carrying out successively again after following steps: b, pre-treatment is sent to SHARON pond, adopts sequencing batch operation mode to carry out short distance nitration denitrogenation processing, and the mud of generation is discharged to sludge sump outward; Waste water after c, SHARON pond process is drained into the UVHSB bio-reactor acidification that is hydrolyzed, and removes some organic pollutants in waste water, improves wastewater biodegradability, and macromolecule contaminant in waste water is degraded to small molecules pollutent to produce sufficient carbon source; Waste water after c, UVHSB bioreactor for treatment is by after receiving mill weir and collecting, and in overflow mode, flows automatically and enters that nitration denitrification is carried out in MBR membrane biological reaction pond and membrane biological reaction is processed, and completes whole sewage disposal flow process.
Like this, after garbage, waste-water pre-treatment, then adopt short distance denitrating technique in conjunction with UVHSB bio-reactor acidication, and MBR membrane biological reactor process, the processing of realization that can high efficient and reliable to kitchen garbage, waste-water, makes it reach emission standard.
