Abstract

The invention relates to the field of water treatment, in particular to a submerged membrane module ultrafiltration filtration device, including a mounting frame, a membrane module filter, a duplex pretreatment filter, a water inlet pipe assembly, an aeration assembly, and a sewage pipe Assembly, water transfer assembly and backwashing purification assembly, membrane module filter and duplex pretreatment filter are all arranged vertically and equidistantly on the mounting frame, and the water inlet end of the membrane module filter is connected to the duplex pretreatment filter The water delivery end at the top is connected, the water inlet end at the bottom of the duplex pretreatment filter is connected with the water inlet pipe assembly, the working end of the aeration assembly is set at the bottom end inside the filter of the membrane module and the input end is connected with the working end of the aeration device, the membrane The inner bottom of the module filter is connected with the external sewage pipe assembly, and the top of the inner filter of the membrane module filter is connected with the water transfer assembly and the backwash purification assembly. The device pre-treats the sewage through the duplex pretreatment filter, and then passes The membrane module filter is used for ultrafiltration, which has better water purification effect and can produce water continuously.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a submerged membrane module ultrafiltration filtration device. Background technique [0002] At present, the ultrafiltration membrane filtration process is widely used in the field of water treatment, and the submerged ultrafiltration membrane process has attracted attention because of its good adaptability to the existing process transformation. There are mainly two types of submerged ultrafiltration membrane modules: curtain type and column type. The main application form is to place the membrane module directly in the membrane tank and form filtration through the suction of the pump. In order to ensure the service life of the membrane and avoid the pollution of the ultrafiltration membrane, it is often necessary to pass the influent water through pretreatment measures such as security filters before entering the membrane tank. [0003] In practical applications, in order to mak...
