Abstract
The utility model discloses a sewage treatment device which comprises a working pool. The working pool is internally provided with at least one group of sewage treatment units. Each sewage treatment unit comprises a contact selective area, a pre-reaction area and a main reaction area sequentially arranged along the length direction of the working pool; aerating systems are arranged at the bottoms of the pre-reaction area and the main reaction area; a water decanter is installed at the tail end of the main reaction area and used for immediately discharging qualified water out of the main reaction area; and sludge reflux pumps and residual sludge collecting pumps are installed at the bottoms of the contact selective area, the pre-reaction area and the main reaction area. According to the device provided by the utility model, due to the arrangement of the sludge contact selective areas, impact load caused by sewage amount and water quality change to the system is reduced and a part of nondegradable COD (Chemical Oxygen Demand) is absorbed and removed, so that the treatment load of subsequent treatment is reduced. The pre-reaction areas are arranged to remove phosphorous and nitrogen. Organic substances in sewage are degraded in the anoxic condition and the power expense is lowered further.
Description
Technical field
The utility model relates to a kind of sewage disposal device, and a kind of specifically CASS sewage disposal device belongs to the environmental protection equipment technical field.
Background technology
At present, because the producer that has of external CASS technology maintains secrecy to its technology, so the data of relevant CASS technology is very limited, most design variable all is semiempirical data.Sewage is after CASS technology, and COD, ammonia nitrogen can reach standard of drainage substantially, but TP, TN be because influent concentration and technology itself, and the TN index is not effectively controlled always.Traditional CAS S process using fixed point spoil disposal technology, it is few sludge volume to occur, moisture percentage in sewage sludge height, characteristics such as pressure filter dehydration difficulty.
The utility model content
Technical problem to be solved in the utility model is, solve the shortcoming that above prior art exists, a kind of sewage disposal device is provided, has simple structure, equipment manufacturing cost is low and the characteristics that occupy little space, and in operation, have incomparable simplicity, handiness and reliability.
The technical scheme that the utility model solves above technical problem is: propose a kind of sewage disposal device, comprise work pool, at least be provided with one group of sewage disposal unit in the described work pool, each described sewage disposal unit includes contact selection district, pre-reaction zone and the main reaction region that sets gradually along the work pool length direction, is provided with aerating system in the bottom of described pre-reaction zone and main reaction region; The tail end of described main reaction region is equipped with strains hydrophone, in order to the qualified water of main reaction region is in time discharged; Select the bottom of district, pre-reaction zone and main reaction region that sludge reflux pump and excess sludge collecting pump all are installed in described contact.
The technical scheme that the utility model further limits is: aforesaid sewage disposal device, described aerating system is made up of ABS engineering plastics pipe, adjusting support, regulated valve, electrically operated valve and blower fan, described blower fan through electrically operated valve and regulated valve be installed in the ABS engineering plastics pipe of regulating on the support and link to each other, on described ABS engineering plastics pipe, be evenly equipped with solarization air cap.
Aforesaid sewage disposal device, described blower fan is made up of at least three Root's blowers that are arranged in parallel.
Further, aforesaid sewage disposal device, described strain hydrophone by push rod, strain tank and floating drum is formed, the described tank of straining links to each other with described floating drum by pipeline, by described floating drum water is discharged; One section of described push rod links to each other with the described tank of straining, and the other end is installed on the sidewall of described work pool, regulates the described height of straining tank by described push rod.
The utility model has the advantages that: the utility model is selected the district by the mud contact is set, the impact load that the reduction sewage water yield, change of water quality are brought to system, and a part of nondegradable COD has been removed in absorption simultaneously, has reduced subsequent disposal partially disposed load; The setting of pre-reaction zone can reach the effect of dephosphorization denitrogenation; The organic substance of sewage has reduced power charge thereby sewage has been degraded under the oxygen condition of holding concurrently.The utility model will just sink in addition, aeration, two heavy combining in the pond carry out, and with the operation in each stage of time variable control, save floor space and initial cost, easily be automated control; Adopt submersible sewage pump as mud overboard pump and reflux pump, needn't build the mud pump house, reduced initial cost, be convenient to maintenance management.
