The utility model is achieved through the following technical solutions, the utility model comprises: three-grid septic tank, pump well, reinforced anaerobic bucket and biological filter, wherein: three-grid septic tank, reinforced anaerobic bucket, biological filter are end to end successively, pump well is connected with three-grid septic tank by bottom pipe, the reinforced anaerobic bucket is connected by rising pipe with three-grid septic tank, and the biological filter is connected by rising pipe with the reinforced anaerobic bucket.
The span of the length of described pump well, width and height is followed successively by 40～60cm, 40～60cm and 50～80cm, vertically is provided with oil weir in the center of pump well, and the length of this oil weir and the span of width are 40～60cm and 30～50cm.
Described oil weir is positioned at the following 15～25cm of ordinary water level of three-grid septic tank and pump well.
The diameter of described bottom pipe is 5cm～10cm, and the degree of depth on the width between centers ground of bottom pipe is 50～80cm, is provided with the slagging-off basket in a bottom pipe side adjacent with pump well, and this slagging-off basket is that the aperture is the plastics system of 2～5mm or bamboo basket.
Described rising pipe is positioned at the following 4～10cm place of inner level, the fertile pond of the storage degree of depth.
Described anaerobism bucket is provided with production well and traverse baffle, wherein: production well be positioned at the anaerobism bucket directly over, traverse baffle vertically is arranged at the inner center of anaerobism bucket, the top of traverse baffle seals the lower openings of traverse baffle with the anaerobism bucket.
The utility model is realized the processing discharging of Rural areas resident living sewage, and method is simple and practical, and is workable, and anaerobism bucket output terminal can connect the biological filter, further improves the filteration of three-grid septic tank.It is little that the utility model is implemented the space, and the whole set of installation operational management is convenient, and treatment effect is good, does not need to use in addition the energy.
