Abstract

Relating to the technical field of water treatment, and in view of the problem that existing cloth media filter backwash systems cannot thoroughly clean up sludge and miscellanies on a filter cloth, the invention discloses a sediment suction system for a cloth media filter. The system includes a suction assembly, a suction pump, a driving mechanism and a sludge discharge pipe. The suction assembly, the suction pump and the sludge discharge pipe are connected in order, and the driving mechanism is connected to the suction assembly. The suction assembly includes an inverted T shaped suction main pipe, and several suction branch pipes connected to the transverse pipeline bottom of the suction main pipe in parallel and communicated with it. One end of the sludge discharge pipe is communicated with the vertical pipeline of the suction main pipe, and the other end of the sludge discharge pipe is communicated with the outside of the filter. The sediment suction system disclosed in the invention is particularly applicable to small and medium-sized water treatment equipment.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a bottom sludge suction system used for suctioning long-term accumulated sludge in filter cloth filters. Background technique [0002] After the filter has been used for a certain period of time, it is necessary to periodically backwash the filter layer. One is to discharge the impurities and dirt in the filter layer with water to clean the filter layer; the other is to reduce the cost of filtration operations in water treatment. resistance. However, due to the instability of the effluent from the sedimentation tank of the sewage plant, there will be large fluctuations in the SS (suspended matter) of the influent water. In addition, the filter tank is generally built outdoors, and sediment or other sundries usually enter the filter tank, which will be in the tank after a long time A sludge deposit layer is formed at the bottom of the body, and the backwash device alone c...
