Integrated sewage MBR treatment device and use method

Abstract

The invention discloses an integrated sewage MBR treatment device and a use method. The integrated sewage MBR treatment device comprises a treatment box, a filtering tank, an anaerobic reaction tank and a membrane filtering tank. The filtering tank, the anaerobic reaction tank and the membrane filtering tank are sequentially arranged in the treatment box from left to right. The top of the filtering tank is connected with one end of a water inlet pipe, the other end of the water inlet pipe extends to the outer side of the treatment box and is connected with a water inlet electromagnetic valve in series, a stirring centrifugal unit is installed on the filtering tank, a filtering net of a conical structure is arranged on the bottom side of the interior of the filtering tank, and a dischargingpipe at the bottom of the filtering net penetrates through the bottom end of the filtering tank and is communicated with the top of a particulate matter collecting box through a connecting pipe sleeve. The blockage of the filtering mechanism is effectively avoided, the replacement frequency of the filtering mechanism can be reduced, an anaerobic agent is actively added during anaerobic treatment,air is exhausted, and the anaerobic treatment efficiency is improved, so that the overall sewage filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated sewage MBR treatment device and a use method. Background technique [0002] The governance of urban rivers follows the technical route of "external source emission reduction, internal source dredging, water quality purification, clean water supply, and ecological restoration". Among them, exogenous emission reduction and internal dredging are the foundation and premise, water purification is a phased means, and hydrodynamic improvement technology and ecological restoration are long-term safeguards; [0003] Now it is suitable for areas with low pollution-holding capacity of the river. The standard of sewage treatment is improved. Generally, the MBR process is used for sewage treatment, and then discharged to the river. However, the existing integrated sewage MBR treatment device needs to be replaced due to the blockage of the filter setting. If the setting...

[0003] Now it is suitable for areas with low pollution-holding capacity of the river. The standard of sewage treatment is improved. Generally, the MBR process is used for sewage treatment, and then discharged to the river. However, the existing integrated sewage MBR treatment device needs to be replaced due to the blockage of the filter setting. The setting is too frequent and the anaerobic treatment takes a long time, resulting in low efficiency of sewage treatment
