Abstract

The invention discloses an automatic washing and automatic repairing device for a filtering membrane. The automatic washing and automatic repairing device comprises an aeration draught fan, a flow distribution chamber, a membrane reaction tank and an effluent suction pump, wherein an air outlet of the aeration draught fan is connected into the flow distribution chamber through a connecting pipeline; the flow distribution chamber is provided with an aeration pipeline and a washing pipeline, which are communicated with the inner part of the flow distribution chamber; the aeration pipeline is provided with an aeration normally open solenoid valve; the washing pipeline is provided with a washing multi-grade normally closed solenoid valve; the aeration pipeline and the washing pipeline are connected into the membrane reaction tank respectively; a filtering membrane assembly and a filtering membrane washing mechanism are arranged at a position, corresponding to the washing pipeline, in the membrane reaction tank; a water suction opening of the effluent suction pump is connected with a water outlet of the filtering membrane assembly in the membrane reaction tank through a water suction pipeline; a pressure sensor is arranged at the water suction opening of the effluent suction pump; and an effluent flow meter is arranged at a water outlet of the effluent suction pump. The invention further discloses a control method of the automatic washing and automatic repairing device for the filtering membrane.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a filter membrane automatic cleaning and repairing device and a control method thereof. Background technique [0002] With the development of sewage treatment technology, especially small sewage treatment systems, in order to reduce the footprint and improve efficiency, more and more filter membranes are used for the separation of sludge and water. While the filter membrane is in use, the surface is easily attached by the sludge and suspended matter in the biochemical reaction tank. With the prolongation of the use time, the attachment on the surface of the filter membrane will increase. If blockage occurs, the water output of the equipment will become smaller and smaller, and some serious cases will be completely blocked, and the equipment will not be able to output water. The current treatment method is to take out the filter membrane as a single piece for cleaning, a...
