[0003] The prior art discloses an invention, the application number is CN201510054930.X, the application publication number is CN104609672A, and the application publication date is 20150513. Oxygen pool, anaerobic pool and secondary aerobic pool and the ultrafiltration disinfection device connected to the waste water outlet of the secondary aerobic pool, the primary aerobic pool is high-load aerobic, and the secondary aerobic pool is low-load good Oxygen, waste water enters from the first-level aerobic pool, then passes through the facultative pool, anaerobic pool and second-level aerobic pool in turn, and finally undergoes ultrafiltration and disinfection by an ultrafiltration disinfection device before being discharged or reused; Set up two-stage aerobic pools, which can deeply degrade pollutants of different natures and refractory toxic and harmful substances, and then further purify the water quality through ultrafiltration disinfection. However, there are still the following problems. Setting up ultrafiltration disinfection devices to purify water quality requires Considering the clogging situation, the purification effect of ordinary ultrafiltration devices is not good, and it is very easy to contaminate and clog, and it is very troublesome to disassemble and clean, and it needs to be replaced regularly, which is inconvenient to use

Abstract

The invention discloses a segmented water inlet membrane treatment device, and belongs to the technical field of sewage treatment. The device sequentially comprises an adjusting tank, a segmented water inlet multi-stage A / O device, a nano-filtration tank and a disinfection clear water tank in the water inlet direction; the nano-filtration tank comprises a tank body, rolling type nano-filtration membranes are arranged on the two sides of the tank body respectively, and openings are formed in the side walls, right opposite to the rolling type nano-filtration membranes, of the tank body. Each rolling type nano-filtration membrane comprises an activated carbon rod which can be rotationally arranged on the tank body and a nano-filtration membrane layer which is wound on the periphery of the activated carbon rod, wherein one end of the nano-filtration membrane layer is fixedly connected to the activated carbon rod, and a cover plate for sealing the corresponding opening is arranged at the other end of the tank body. A water inlet is formed in the upper end of the tank body, the lower end of the tank body is provided with a water outlet for discharging intercepted sludge, the center of each activated carbon rod is provided with a central channel, the lower end of each activated carbon rod is sealed, dialysate outlets communicated with the central channels are formed in the upper endsof the activated carbon rods, and the dialysate outlets are connected with a water outlet pipeline communicated with the disinfection clear water tank through rotary joints. The segmented water inletmulti-stage A / O device is combined with nano-filtration, so that the nano-filtration membranes are cleaned conveniently while the water quality is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a segmented water inlet membrane treatment device. Background technique [0002] my country is a water-scarce country, and sewage treatment and reuse are effective measures to develop and utilize water resources. Sewage reuse is to use domestic sewage for non-drinking purposes such as greening, flushing, and replenishment of ornamental water after further treatment, while using clean water for drinking and other purposes with high water quality requirements. Sewage reuse has been widely used in many water-scarce areas in the world, and it is considered the most practical technology for sewage treatment in the 21st century. The equipment used for sewage recovery and treatment is suitable for the treatment and reuse of domestic sewage in residential quarters, shopping malls, restaurants, schools, troops, hospitals, highways, railways, factories, mines, tourist attractions...
