Embodiment Construction

[0016] The invention delays the membrane fouling by increasing the flow velocity of the membrane surface and reducing the concentration polarization through the circulation pump, so that the cleaning period of the membrane module is longer and the service period of the membrane bioreactor is improved.

[0017] exist figure 1 In the process, after the rising mixed liquid is separated by the mud-water separator 6, the granular sludge settles under the action of gravity, and the supernatant liquid separated by the self-made circulating water inlet 1 is transported to the membrane module 3 through the circulating pump 2, and the permeate passes through the membrane The components are collected, the self-made circulating water outlet 4 and the concentrated solution concentrated by the membrane is transported to the bottom of the bioreactor 5 under pressure, and mixed with the high-concentration mixed solution at the bottom under the action of high-pressure and high-speed flow, and ...

Abstract

The invention discloses an internal circulation anaerobic membrane bioreactor sewage treatment device, which relates to an engineering sewage treatment device, in particular to a sewage treatment and reclaimed water reuse device. The device comprises a bioreactor, a membrane module, a circulating pump and a relay. The internal circulation anaerobic membrane bioreactor sewage treatment device is formed by the following steps that: a self-made circulating water inlet (1) is connected with the circulating pump (2); the circulating pump (2) is connected with the membrane module (3); the upper part of the membrane module (3) is connected with a mud-water separator (6); and the lower part of the membrane module (3) is connected with a self-made circulating water outlet (4) through the bioreactor (5). The device can be applied to the treatment of high concentrated wastewater of municipal engineering, light industry (such as beer, beverage and so on) and slaughtering industry and so on.

Description

technical field [0001] The invention relates to municipal engineering sewage treatment equipment, in particular to sewage treatment and reclaimed water reuse equipment. It can be applied to the treatment of high-concentration wastewater such as municipal engineering, beer, beverage and other light industries, and slaughtering industries. Background technique [0002] my country is one of the 13 water-poor countries in the world. The per capita water volume is only 2630m 3 , the per capita amount of resources is only 1 / 4 of the world's per capita water resources. Nearly 80% of the cities in the country are short of water, and the annual economic loss caused by water shortages reaches 120 billion yuan. At present, the waste of water resources in my country is very serious. The utilization rate is only 40% to 50%, the utilization rate of industrial water is 30% to 40%, and the water consumption quota per unit of product is high, often more than 10 times higher than that of dev...
