Problems solved by technology

At present, the main methods to alleviate membrane fouling include chemical modification of the membrane surface, pretreatment of the mixed solution, adding fillers to the sludge mixed solution, and optimization of operating conditions. However, the integrated granular activated carbon-dynamic membrane bioreactor treatment Sewage technology is rarely reported
[0004] In view of the fact that the existing MBR process uses pumps to pump water out, and the high price of membrane modules and the rapid decrease in flux caused by membrane fouling lead to high operating costs and limit the promotion of MBR technology, this case arose from this

Embodiment Construction

[0014] The specific details of its implementation will be described below in conjunction with the accompanying drawings for the present invention. Such as figure 1 As shown, the present invention's integrated granular activated carbon-dynamic membrane bioreactor sewage treatment device and its treatment process are realized through the following steps:

[0015] First, the cheap and easy-to-obtain industrial polyester filter cloth is used as the membrane substrate of the dynamic membrane bioreactor to make the membrane module 7, and at the same time, a polypropylene carrier is added to the inside of the membrane module 7 to form an anoxic environment. Next, aeration pipe 4 and mud discharge pipe 5 are installed at the bottom of reactor 8, membrane module installation bracket 3 is installed in the middle, and membrane module 7 is placed in membrane module installation bracket 3; On the side wall of the reactor 8. Granular activated carbon 11 and activated sludge with a particl...

Abstract

The invention discloses an integrated GAC (granular activated carbon)-DMBR (dynamic membrane bio-reactor) sewage treatment device which comprises a raw water tank and a reactor, wherein the reactor is connected with the raw water tank by a through pipe; a membrane-assembly mounting bracket is installed in the reactor, a membrane assembly is installed in the membrane-assembly mounting bracket, and the bottom of the reactor is provided with an aerator pipe and a sludge discharge pipe; the aerator pipe is fixedly connected with an aeration blower; and granular activated carbons are uniformly distributed in the reactor. The invention also discloses a treatment process for granular activated carbons. The device and process disclosed by the invention have the characteristics of slow membrane pollution, high treatment efficiency, long running period, easy cleaning and large membrane flux.

Description

technical field [0001] The invention belongs to the field of purification and treatment of sewage resources, in particular to an integrated granular activated carbon-dynamic membrane bioreactor sewage treatment device and a treatment method thereof. Background technique [0002] Membrane bioreactor (MBR), as a new type of sewage treatment process, is an organic combination of traditional activated sludge method and membrane separation technology. It has high treatment efficiency, good effluent quality, simple process, compact equipment, small footprint, Easy to realize automatic control, simple operation and management and other outstanding features. Although MBR is already a relatively mature treatment technology, there is still the problem of large initial construction investment, mainly because the price of membrane modules is high; due to the direct contact between the membrane and sewage and sludge, the problem of membrane fouling is also very prominent. Membrane fouli...
