Tension type MBR flat membrane water treatment system

Abstract

The invention discloses a tension type MBR flat membrane water treatment system which comprises an aeration box and a membrane box, the top of the aeration box is fixedly connected with the membrane box, and a membrane assembly is installed in the membrane box through a fixing mechanism. According to the tension type MBR flat membrane water treatment system disclosed by the invention, the plurality of membrane elements are arranged on the four limiting rods at equal intervals in a sleeving manner, and the elastic limiting assemblies are arranged on the limiting rods and located between every two adjacent membrane elements, so that gaps between the adjacent membrane elements are stable, and the use stability of the tension type MBR flat membrane water treatment system is improved. An elastic limiting assembly is adopted for limiting, so that when the membrane element is subjected to large impact force of water flow, the stress of the membrane element can be reduced through elastic buffering of the elastic limiting assembly, the membrane element is prevented from being deformed and damaged, and the membrane element further has certain vibration under the impact force of the water flow. Through combination with an aeration pipe, the sludge generated by filtration is more easily separated from a membrane component, so that the use stability of the membrane component is further improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a tension type MBR flat membrane water treatment system. Background technique [0002] Sewage treatment (wastewater treatment): The process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. In sewage treatment, water resource reuse MBR, also known as Membrane Bio-Reactor (Membrane Bio-Reactor), is a new type of water treatment technology that combines a membrane separation unit with a biological treatment unit. According to the structure of the membrane, it can be divided into flat membrane, tubular membrane and hollow fiber membrane, etc., an...

Problems solved by technology

[0003] In the existing tension-type MBR flat membrane water treatment system, the membrane module is composed of several membrane elements. Generally, the membrane elements are directly inserted into the limit grooves opened on the membrane module fixing frame, so that the distance between adjacent membrane elements Certainly, with such a structural design, when the membrane member is impacted by the water flow, it lacks a buffer structure and is easily deformed and damaged. Secondly, the membrane element will not vibrate during use, and the membrane element will be washed by the aeration tube alone. , the cleaning effect is poor, so it cannot meet the needs of users
