Description

Sewage purification device of town sewage pipe network Technical Field The application relates to the technical field of sewage treatment, in particular to a sewage purification device of a town sewage pipe network. Background With the acceleration of urban process in China, the discharge amount of urban sewage is increased increasingly, and higher requirements are put on the treatment capacity of sewage pipe networks. The traditional urban sewage pipe network mainly bears the functions of sewage collection and transportation, lacks the purification treatment capacity of sewage, and causes a large amount of untreated sewage to be directly discharged into a water body, thereby causing serious environmental pollution. In order to solve this problem, in recent years, some researchers have proposed a scheme of integrating a purification function in a sewage pipe network, and various sewage pipe network purification devices have been developed. The devices initially purify sewage by arranging units such as filtration, sedimentation, biological treatment and the like in a pipe network so as to relieve the pressure of a tail-end sewage treatment plant. However, in practical application, town sewage may contain a large amount of suspended matters, impurities and other substances which are easy to block, and these substances are easy to accumulate in a filtering unit, a runner or a processing unit of the purification device, so that a water flow channel is blocked, the processing efficiency of the device is reduced, and the problems of pipe network overflow and the like are caused, so that obvious defects exist. Disclosure of utility model In order to solve the problem that suspended matters and impurities are easy to block a purification device, the application provides a sewage purification device of a town sewage pipe network. The application provides a sewage purification device of a town sewage pipe network, which adopts the following technical scheme: The utility model provides a sewage purification device of town sewage pipe network, includes the open filtering ponds in top, the intercommunication has inlet tube and outlet pipe on the filtering ponds, the inlet tube extends to in the filtering ponds, placed in the filtering ponds and filtered the water-permeable bag, it has the clearance mouth just to open to filter the inside cavity of water-permeable bag, clearance mouth department is through the tensioning belt banding on the inlet tube. By adopting the technical scheme, sewage enters the filtering water permeable bag from the water inlet pipe, and because the aperture of the filtering water permeable bag is smaller, the sewage can pass through the filtering water permeable bag to the filtering tank, and suspended matters, impurities and the like can only be intercepted in the filtering water permeable bag, so that the possibility of blocking the water purifying device by the suspended matters, the impurities and the like is reduced. Optionally, a limiting ring is arranged on the outer side wall of the water inlet pipe, and the tensioning belt is positioned on one side of the limiting ring, which is opposite to the inner cavity of the filtering water permeable bag. Through adopting above-mentioned technical scheme, the spacing ring plays spacing effect to the tensioning area, has reduced the possibility that the filtration water permeable bag receives sewage impact and drops from the inlet tube. Optionally, a hanging frame is arranged on the filter tank, a hanging belt for hanging on the hanging frame is arranged on the filter water permeable bag, and when the hanging belt is hung on the hanging frame, the filter water permeable bag is suspended. Through adopting above-mentioned technical scheme, when filtering the water permeable bag in-process that uses, the workman hangs the area of hanging on the stores pylon to this makes the water permeable bag of filtering keep unsettled state, ensures the transmission efficiency of sewage from the water permeable bag of filtering. Optionally, the hanger is arranged on the filter tank in a sliding way, a hook is arranged on one side of the hanger, a hanging rope is tied on the hook, and the other end of the hanging rope opposite to the hook is tied on a hanging belt. Through adopting above-mentioned technical scheme, when filtration permeable bag fully carries suspended solid and impurity, the workman pulls through hanging rope and holds filtration permeable bag and upwards promotes, wait to filter after the sewage draining in the permeable bag, is pushing the stores pylon and makes the filtration permeable bag be close to the edge of filtering ponds, and then conveniently takes off it and clear up. Optionally, reserve the ribbon that is used for the ligature clearance mouth on the filtration water-permeable bag. Through adopting above-mentioned technical scheme, the ribbon is sealed to the clearance mouth realization ligature, has reduced the possibility that suspe
