Abstract
The invention discloses a sedimentation tank filter weir, comprising a sedimentation tank, a water outlet groove arranged at the periphery of the sedimentation tank, and a mud scraper and sucker, wherein the two ends of the rack of the mud scraper and sucker are provided with machine wheels which are supported by the tank wall, the mud collecting groove of the mud scraper and sucker is fixedly connected with the rack, a water chute taking the side wall of the water outlet groove as a common wall is arranged on the side surface of the water outlet groove, the other side wall of the water chute is a water filtering plate assembly consisting of filter cloth and a grating rack, the upper part of the water filtering plate assembly is provided with a dash plate, the upper part of the common wall of the water chute is provided with a movable water outlet weir plate, the outer side of the water filtering plate assembly is adhered with a movable back-flushing suction cup, the back-flushing suction cup is hinged with a connection rod and hinged with the rack of the mud scraper and sucker by the connection rod, a tension spring is installed between the connection rod and the rack, the back-flushing suction cup is connected with a flexible straw, the other end of the flexible straw is positioned on the mud collecting groove of the mud scraper and sucker, the flexible straw is provided with a self-suction pump, and the self-suction pump is fixedly connected with the mud scraper and sucker. According to the technology, the suspended matter discharging when in the water treatment in the sedimentation tank can be reduced, the grade of sewage treatment and drainage can be improved, the filter structure is simple, and the cost is low.
Description
Technical field
It is the filter that is used for the sewage disposal final sedimentation tank that the sedimentation basin that the present invention relates to filters the weir.
Background technology:
The sewage discharge one-level B of the country of municipal sewage treatment enterprise general execution at present standard, indicator of suspended solids SS≤20mg/L in the one-level B standard, if sewage disposal will be upgraded to the discharge standard of one-level A, indicator of suspended solids SS≤10mg/L.Use rotary disc filter to handle at present and can realize one-level A discharge standard, need to build separately factory building but rotary disc filter is installed, equipment manufacturing cost is also expensive, is restricted so improve the water treatment discharge standard.
Summary of the invention
The purpose of this invention is to provide a kind of sedimentation basin and filter the weir, can reduce the suspension of sedimentation basin discharge water, improve the grade that sewage disposal is discharged, and filtration is simple, cost is low with present technique.
Technical scheme of the present invention is: a kind of sedimentation basin filters the weir, comprises sedimentation basin, is located at the peripheral effluent trough of sedimentation basin, comprises that wheel is equipped with at the boat frame two ends of scraping and sucking machine, scraping and sucking machine; Wheel is supported by pool wall, and the mud-collecting slot of scraping and sucking machine is connected with the boat frame, and it is characterized in that: being provided with the effluent trough sidewall in the effluent trough side is the guiding gutter of common wall; The water filter plate assembly that another sidewall of guiding gutter is made up of filter cloth and grills, water fender is equipped with on water filter plate assembly top, and movable water outlet weir plate is equipped with on the common wall top of guiding gutter; Mobile backwash sucker is posted in the outside of water filter plate assembly; Backwash sucker and rod hinge connection, and hinged through connecting rod and scraping and sucking machine boat frame, between connecting rod and boat frame extension spring is housed; The backwash sucker is connected with soft suction pipe; The soft suction pipe other end places on the mud-collecting slot of scraping and sucking machine, on the soft suction pipe self priming pump is housed, and self priming pump and scraping and sucking machine are connected.
The invention has the advantages that: 1, increased guiding gutter with filtering function in the original effluent trough of sedimentation basin front; Because the fiber cloth density of guiding gutter is 10 microns; Be widely used on the water treatment facilities such as rotary disc filter; Go out water concentration below 10mg/L, so improved the grade of sewage disposal discharging.2, effective filtration area is big, and water filter plate and effluent trough are parallel, so water filter plate is peripheral around sedimentation basin, can reduce water outlet weir plate front and back liquid level difference because filter area is big, improves filter effect.3, backwash equipment is installed on the scraping and sucking machine, need not to resume the place, can save a large amount of early investment funds; 4, with the present technique grade of increasing water quality, do not need to build separately factory building, both can design on newly-built water treatment facilities, also can transform old water treatment facilities, it is simple in structure, and installation and maintenance are convenient, reduces cost.
