MBR membrane set device hoisting system of membrane workshop of buried sewage treatment plant and application of MBR membrane set device hoisting system

Abstract

The invention provides an MBR membrane set device hoisting system of a membrane workshop of a buried sewage treatment plant. The membrane workshop is provided with multiple membrane pool galleries (7)and at least one cleaning pool (6). The system further comprises a ground straight rail (1) arranged transversely, an electric hoist guide rail (3) arranged above all the membrane pool galleries (7)and the cleaning pools (6) in the longitudinal direction, a flat car movement control device and an electric hoist control device. The ground straight rail (1) is arranged on the longitudinal side ofthe membrane pool galleries (7) and the cleaning pools (6). A rail type flat car (2) capable of moving along the rail is arranged on the ground straight rail (1). An electric hoist (5) is arranged onthe electric hoist guide rail (3). By means of the MBR membrane set device hoisting system, work time can be greatly reduced, the transportation distance of the membrane set device can be effectivelyreduced, and the transportation loads of the electric hoist can be reduced; and in addition, damage caused by colliding to the membrane set device can be effectively avoided, and therefore the servicelife of the membrane set device is prolonged.

Description

【Technical field】 [0001] The invention relates to an MBR membrane module hoisting system in a membrane workshop of an underground sewage treatment plant, and the application of the system in hoisting an MBR membrane module, belonging to the technical field of water treatment. 【Background technique】 [0002] The shortage of water resources and serious water pollution have seriously restricted the sustainable development of my country's economy and ecology. In order to strengthen water pollution treatment and improve the effluent water quality of sewage treatment plants, new and efficient sewage treatment processes have been developed and utilized. Among them, the MBR (membrane bioreactor) process has become the most widely used sewage biological treatment process in recent years due to its advantages of good effluent quality and small footprint. [0003] However, the membrane fouling problem is one of the common problems of the MBR process. In order to solve the membrane fou...
