Background technology
Currently, with the rapid development of China's industry, the problem of thing followed is environmental protection, especially production generates Sewage handling problem, although sewage-treatment plant is varied, in use still have many defects.In the prior art Common sewage disposal device mostly uses the processing pond composition of multistage continuous arrangement setting, by precipitation or filtration treatment it is up to standard after Discharge outward.
Application No. is the patents of invention of CN201710035579.9 to disclose a kind of sewage disposal system, including processing is originally Body, the sewage disposal ontology include the first treatment tank, the second treatment tank and third treatment tank, the sewage Processing body edges are fixed with fence, and sewage water inlet pipe is equipped in first treatment tank, is set at the sewage water inlet pipe There is sewage control device, is equipped with sewage-treatment plant in first treatment tank, first treatment tank passes through defeated Send pipe to be connected with the second treatment tank, be equipped with filter press in second treatment tank, second treatment tank with It is equipped with discharge outlet between third treatment tank, filter screen is equipped at the discharge outlet, can be easy to use, the processing of sewage Effect is good, and treated, and sewage can be directly discharged in river, is not damaged to environment.But this kind of sewage treatmentmethod is deposited In following disadvantage:
(1)The treatment tank in the prior art used generally uses open top for the processing of guarantee filtrate or deposit The pond of type, this pond sealing is bad, often has peculiar smell discharge, although the purifying processing to sewage can be realized, to meeting Environment causes serious gaseous contamination.
(2)Treatment tank is inherently bigger, it causes occupation of land face by the way of multistage continuous arrangement setting in addition Product is big, and capital construction is of high cost, and general small business all holds on site area and construction cost dares not accept, and is unfavorable for efforts at environmental protection Smooth development.
(3)Deposit cleaning in treatment tank is inconvenient, and when cleaning needs to be cleared up by other bucket class equipment Operation, workload is big, and cleaning efficiency is low, and can not achieve the thorough cleaning to deposit, influences subsequent job, can not achieve The continuous production process of sewage disposal.
Invention content
The present invention in order to solve the problems in the prior art, provides a kind of vertical sewage treatment device of segment processing, accounts for Ground area is small, centralization degree is high, can carry out segmented processing to sewage, and realize self-cleaning function.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:A kind of vertical sewage disposal of segment processing Device, it includes the treating column of vertical, and arranged for interval has multiple horizontal baffles successively from the bottom to top in treating column, each horizontal Partition board is sealedly and fixedly connected with treating column, to which tower internal cavity is divided into multiple process chambers arranged up and down;Adjacent process chamber Between connect to form snakelike walking path by connecting pipe, wherein positioned at lower side process chamber be equipped with water inlet, be located at The process chamber of top side is equipped with water outlet;
By-pass line is further connected on the connecting pipe, by-pass line is equipped with bypass cock valve, is located at bypass on by-pass line The upstream or downstream of switch valve are additionally provided with water sample detection device;It is equipped with to be connected to the downstream of by-pass line interconnecting piece on connecting pipe and cut Disconnected valve;
It is equipped with sewage filter device in each process chamber, sewage filter device includes multiple being intervally arranged successively along flow trend Filtering sheet frame, filtering sheet frame periphery is tightly connected with corresponding process chamber, and each filter sheet frame be obliquely installed;Adjacent mistake Carry out filtering sheet frame before being referred to as to the filtering sheet frame of side positioned at flow in filter plate frame, is located at the filtering sheet frame of flow whereabouts side Sheet frame is filtered after referred to as, after projection of the preceding filtering sheet frame upper edge at the bottom of alignment processing room on partition board is located under filtering sheet frame The front side on edge;
It each handles indoor filtering sheet frame to tilt to side towards flow, the direction of the adjacent indoor filtering sheet frame of processing On the contrary;When carrying out sewage disposal, from the water inlet into sewage, and it is discharged from the water outlet;When carrying out deposit cleaning, from The water outlet is discharged into cleaning water, and from the water outlet;
Each process chamber is additionally provided with deposit guiding device, and deposit guiding device includes the draining being arranged on alignment processing room Pipe, conveying direction and the indoor flow of alignment processing of drainpipe move towards perpendicular, in same process chamber adjacent head sheet frame it Between be filter chamber, the bottom of each filter chamber is equipped with the drainpipe, and drainpipe is equipped with drainage switch valve.
The angle of inclination of filtering sheet frame in same process chamber is consistent.
The drainpipe accesses main sewer outward, and water pump is equipped on main sewer.
The filter opening diameter that sheet frame is filtered in different disposal room is different, and straight positioned at the lower section indoor filtering sheet frame filter opening of processing Diameter is more than top and handles indoor filtering sheet frame filter opening diameter.
The corresponding partition board in the filter chamber bottom is equipped with wavy bulge.
The wavy bulge is arranged along the conveying direction of drainpipe to be arranged.
The treating column is the cylindrical barrel body structure that cross section is rectangle.
The filtering sheet frame be and the matched square structure of process chamber section configuration.
