Technical Field

The utility model belongs to the technical field of the treatment of factory domestic sewage, concretely relates to factory domestic sewage handles recycle integration equipment.

Background

In the existing plant domestic sewage treatment equipment, the adopted sewage treatment method mainly comprises an activated sludge method and corresponding treatment equipment. For the treatment of factory domestic sewage, A2O (or MBR) process is mostly selected, but A2O needs sludge backflow, and the quality of effluent water cannot be guaranteed due to sludge bulking or insufficient sludge activity caused by improper management.

The domestic sewage of the plant area has the characteristics of wide distribution, small water quantity and large water quality fluctuation, and the problem to be solved is how to effectively improve the treatment efficiency and the treatment quality of the domestic sewage to relieve the current situation of water resource shortage of the plant area.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a plant area domestic sewage treatment and recycling integrated device. The requirements of removing pollutants in domestic sewage of various factories and reducing the dosage of treatment agents are met.

The utility model adopts the technical proposal that: the utility model provides a factory domestic sewage handles recycle integration equipment, includes the room body, locates equalizing basin, anaerobism biological filter, bological aerated filter, membrane separation bioreactor, the disinfection pond of arranging in proper order around the indoor in proper order, set up the water inlet on the room body of equalizing basin one side, set up the mouth of a river on the room body of disinfection pond one side.

In a further preferable structure, the anaerobic biological filter is filled with solid fillers, part of anaerobic microorganisms are attached to and grow on the fillers to form an anaerobic biological film, and the other part of anaerobic microorganisms is in a suspended state in gaps among the fillers.

In a further preferred structure, the membrane separation bioreactor is a novel water treatment device which is combined by a membrane separation unit and a biological treatment unit. Active sludge and macromolecular organic matters in the biochemical reaction tank are retained by utilizing membrane separation equipment, clear water is separated, the biochemical reaction and the clear water are synchronously separated, and a secondary sedimentation tank is omitted.

In a further preferred structure, the filler in the biological aerated filter is porous ceramsite.

In a further preferred structure, a grille is arranged at the water inlet in the chamber body.

In a further preferable structure, the adjusting tank, the anaerobic biological filter, the aeration biological filter, the membrane separation bioreactor and the chamber body at the top of the disinfection tank are all provided with ventilation openings.

The utility model has the advantages as follows:

compare the concrete pond, the utility model discloses no matter the integration equipment all has obvious advantage from investment, construction progress and later stage operation maintenance, comprehensive consideration takes up an area of, economic nature and practicality, the utility model discloses an anaerobism biofilter + aeration Biofilter (BAF) + membrane separation bioreactor (MBR) replaces current A2O technology, realizes the processing retrieval and utilization to factory domestic sewage.

Wherein, the aerating biological filter (BAF) filler selects porous ceramsite to efficiently treat pollutants, the concentration of the pollutants can be effectively reduced, the use amount of a pretreatment flocculant and the treatment load of a subsequent membrane separation bioreactor (MBR) are reduced, and the washed ceramsite can be recycled, so that the operation and economic benefits are high.

The BAF is a novel high-load immersed fixed biological membrane three-phase reactor, integrates the characteristics of biodegradation, aeration, high filtration speed, suspended matter interception, regular back washing and the like, and compared with an A2O process, the BAF takes small particles as a filter material, has large specific surface area and strong microbial adhesion, does not need sludge backflow or sludge expansion, is very convenient to maintain and manage after automatic back washing, saves the occupied area, and ensures the quality of outlet water.

Meanwhile, in order to adapt to the fluctuation of the quality of inlet water, an anaerobic biofilter is additionally arranged at the front section, and an MBR is additionally arranged at the tail end to ensure that the outlet water can reach the water quality standard of urban waste water recycling urban miscellaneous water.
