The technical scheme is as follows: in order to achieve the above object, the present invention is specifically realized as follows: an AB method unpowered purifying device applied to mountain areas comprises an anaerobic purifying tank at the front section and an aerobic purifying device at the rear section, wherein a communication pipeline is arranged between the anaerobic purifying tank and the aerobic purifying device; the anaerobic purifying tank is higher than the aerobic purifying tank. The height difference is utilized to realize the powerless from the anaerobic stage to the aerobic stage, and the dispersing dripping device can fully oxygenate the anaerobic stage to the aerobic stage, so that the treatment effect of the aerobic stage is further improved.
Further, a drainage tube is arranged in the tank body of the dispersion drip tank, one end of the drainage tube is connected with a communicating pipeline between the anaerobic purification tank and the aerobic purification device, the other end of the drainage tube is vertically connected with one or a plurality of guide needle tubes, a dispersion funnel is hung at the tail end of the guide needle tube, and a space is reserved between the dispersion funnel and the bottom of the dispersion drip tank. The dispersion funnel can make the water flow more dispersed.
Further, the diameter of the communicating pipeline is larger than that of the drainage tube, and the diameter of the drainage tube is larger than that of the guide needle tube. By reducing the diameter of the pipeline, a certain pressure difference is formed, so that the effluent has a certain pressure.
Further, the guide needle tube is made of stainless steel and is vertically downward. The water flows to the lower part, and the stainless steel material is not easy to corrode and has larger pressure resistance.
Further, the edge of the dispersing funnel is provided with barbs. Atomizing the water flow dropped from the high place to make the water fully contact with the air for oxygenation.
Further, the barbs are triangular. The triangle has better effect on atomizing sewage.
Further, the vent is a reverse inclined pipeline with a downward notch, so that water mist can be prevented from flowing into the vent pipeline.
The structures of the anaerobic purifying tank and the aerobic purifying tank are as follows: a vertical partition plate divides an inner cavity of a shell into a left area and a right area which are mutually communicated with each other at the top and the bottom, an inflow opening is positioned at the upper part of the left area, and an outflow opening is positioned at the upper part of the right area and lower than the inflow opening. Compared with triangular or polygonal rows, the hollow circular frame has a shape which is more matched with the national standard septic tank, and has better structural stability. After the elastic filler penetrates through the whole support, the support can be used without installing the elastic filler on site and directly put into use, and the support has stronger water flow impact resistance.
Further, holes are formed in the hollow annular frame above the uppermost support plate, and can be used as through holes for string-inserting beam-shaped elastic fillers, so that the distribution area of the fillers is enlarged, and the holes can also be used as water permeable holes for water.
Furthermore, the head end and the tail end of the beam-shaped elastic filler are positioned on the same surface of the same layer of support plate. The head end and the tail end of the elastic filler are fixed through the fasteners, for example, the head end and the tail end are fixed by the same clamp, the elastic filler cannot fall off, the head end and the tail end of the bunchy elastic filler which are respectively fixed by the two clamps can be used, and the clamp fixing mode is simpler, more convenient and firmer.
The dispersing drip tank is communicated with the left area of the aerobic purification tank, the dispersing funnel disperses water flow and aerates the water flow into the left area of the aerobic purification tank, and the water flow is treated by the string-inserted bunchy filler device.
In the anaerobic purification tank and the aerobic purification tank, a filtering unit is arranged at the position of the drainage port, the bottom of a left cavity and the bottom of a right cavity of the filtering unit are communicated, the bottom of the left cavity is provided with the filtering tank, the bottom of the filtering tank is communicated with the right area, and the right cavity is communicated with the drainage port. The non-trapped suspended matter can be further trapped and removed by the filter tank.
Further, one end of a cleaning bent pipe is connected with the top of the filter tank, the other end of the cleaning bent pipe penetrates out of the left cavity and stretches into the right area, and the position of the cleaning bent pipe penetrating out of the left cavity is between the lowest point of the inflow port and the lowest point of the drainage port. The filter plug can be effectively and automatically cleaned by automatically cleaning the bent pipe without a power suction pipe mode, a flushing mode, an expansion mode or an air mode.
The inflow opening is connected with a vertical pipe which extends into the left area, and the position of the outlet of the vertical pipe is lower than the lowest point of the drainage opening. The height difference exists between the inflow opening and the outflow opening, so that unpowered water circulation is realized, and meanwhile, the inflow of the equipment is buffered through the arrangement of the vertical pipe.
Furthermore, the device is formed by injection molding of materials such as recycled plastic polypropylene, polyethylene, POM, nylon, cyclopentadiene resin and the like. Can be injection molded once in production, has high production efficiency and is not easy to crack and leak water.
The beneficial effects are that: compared with the prior art, the invention has the following advantages:
1. the dispersing drip device and the ventilation opening are used without an aeration device, and the sewage is in full contact with the air, so that the initial assembly cost and the running cost are reduced to a certain extent;
