Abstract
The utility model discloses wastewater treatment equipment for corn deep-processing. The equipment comprises a wastewater buffering and collecting tank, a primary settling tank and a mixing tank, wherein supernate of the mixing tank automatically flows into the mixing tank, and a sludge pump is arranged at the lower part of the primary settling tank to pump settled sludge to a sludge treatment system. The mixing tank is connected with an alkali adding pipeline to adjust the PH value of wastewater and is communicated with an anaerobic reactor which is sequentially communicated with a facultative tank, a first level aerobiotic tank, a secondary aerobiotic tank, a secondary settling tank and a coagulative precipitation tank through a pipeline. The facultative tank precipitates flocculent sludge and degrades pollutants by using aerobic micro-organisms, and the pollutants disinfected by a quick filter tank enter a workshop production system. The wastewater treatment equipment disclosed by the utility model is convenient to manage and operate and can treat wastewater of corn deep-processing enterprises. Water quality after treatment can reach the discharge demand regulated in Pollution Discharge Standard of Starch Industrial Water, and wastewater can be recycled to a circulating production system, so that water-saving, energy-saving and emission-reducing purposes are realized.
Description
Technical field
The utility model relates to a kind of corn deep processing wastewater treatment equipment, belongs to the corn deep processing technology field.
Background technology
China is the country of a water resources shortage, and along with the fast development of Chinese society economy, the contradiction of lack of water is on the rise.Corn deep processing enterprise is the water consumption rich and influential family, the various pollutents that discharge in its course of processing are the organic waste water of high density especially, also make corn deep processing enterprise become higher concentration organic contamination rich and influential family, therefore, corn deep processing waste water is carried out advanced treatment, and be back to use circulating production system, can save a large amount of fresh waters on the one hand, simultaneously also directly reduced the quantity discharged of Wastewater Pollutant, to enterprise's water saving, realized that energy-saving and emission-reduction have great significance.
The utility model content
The purpose of this utility model is to provide a kind of corn deep processing wastewater treatment equipment, the corn deep processing enterprise wastewater can be processed, make its water quality can reach the requirement of the special emission limit of regulation in " starch industry pollution discharge standard ", realize water saving, energy-saving and emission-reduction.
to achieve these goals, the technical solution of the utility model is: a kind of corn deep processing wastewater treatment equipment, comprise waste water cushioning collecting pond, by collecting, cushion, regulating, completing the preliminary mixing of waste water regulates, described waste water cushioning collecting pond is connected with a heavy pond by lift pump, the top in one heavy pond has pipeline to be connected with preparing pool, make the supernatant liquor gravity flow on a top, heavy pond enter preparing pool, the bottom in one heavy pond arranges sludge pump, and be connected with sludge treating system, a heavy pond precipitating sludge pump drainage is entered sludge treating system, described preparing pool has the alkali of adding pipeline to be connected into, waste water is carried out being connected with anaerobic reactor after pH value is regulated, described anaerobic reactor adopts UASB technique to process, be connected with oxygen compatibility pool through pipeline, the described oxygen compatibility pool floc sludge that gravity flow is taken out of to anaerobic reactor precipitates, by the road with the one-level Aerobic Pond, the secondary Aerobic Pond, second pond, coagulative precipitation tank is connected successively, make good use of the oxygen animalcule degradation of contaminant, at second pond precipitation residual particles mud thing, in the further advanced treatment of coagulative precipitation tank, then enter Workshop Production system through disinfection by chlorine dioxide by pipeline through fast filter chamber.
Further, described one heavy pond arranges the center driving mud and slag scraping machine.After being removed, the scum silica frost that forms in precipitation process enters into sludge treating system.
Further, described adding, arrange line mixer and volume pump on the alkali pipeline, controls the buck flow, avoids that in preparing pool, the waste water pH value occurs than great fluctuation process, and then affect the normal operation of anaerobic reactor.
Further, between described preparing pool and anaerobic reactor, warming apparatus is set, guarantees still to satisfy when waste water in the winter time the anaerobic treatment condition.
Wastewater treatment equipment management operating of the present utility model is convenient, the corn deep processing enterprise wastewater can be processed, the generation sludge quantity is few, the mud that wastewater treatment produces can send boiler combustion after thickening, water quality after it is processed can reach the requirement of the special emission limit of regulation in " starch industry pollution discharge standard ", and can be back to use in circulating production system, realize water saving, energy-saving and emission-reduction.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
as shown in Figure 1, corn deep processing wastewater treatment equipment of the present utility model, comprise waste water cushioning collecting pond, by collecting, cushion, regulating, completing the preliminary mixing of waste water regulates, described waste water cushioning collecting pond is connected with a heavy pond by lift pump 1, the top in one heavy pond has pipeline to be connected with preparing pool, make the supernatant liquor gravity flow on a top, heavy pond enter preparing pool, the bottom in one heavy pond arranges sludge pump 2, and be connected with sludge treating system, a heavy pond precipitating sludge pump drainage is entered sludge treating system, described preparing pool has the alkali of adding pipeline to be connected into, waste water is carried out being connected with anaerobic reactor after pH value is regulated, described anaerobic reactor adopts UASB technique to process, be connected with oxygen compatibility pool through pipeline, the described oxygen compatibility pool floc sludge that gravity flow is taken out of to anaerobic reactor precipitates, by the road with the one-level Aerobic Pond, the secondary Aerobic Pond, second pond, coagulative precipitation tank is connected successively, make good use of the oxygen animalcule degradation of contaminant, at second pond precipitation residual particles mud thing, in the further advanced treatment of coagulative precipitation tank, then enter Workshop Production system through disinfection by chlorine dioxide by pipeline through fast filter chamber.
Described one heavy pond arranges center driving mud and slag scraping machine 3.After being removed, the scum silica frost that forms in precipitation process enters into sludge treating system.
Described adding, arrange line mixer and volume pump on the alkali pipeline, control the buck flow, avoids that in preparing pool, the waste water pH value occurs than great fluctuation process, and then affect the normal operation of anaerobic reactor.
Between described preparing pool and anaerobic reactor, warming apparatus is set, guarantees still to satisfy when waste water in the winter time the anaerobic treatment condition.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model is within all falling into protection domain of the present utility model.
