EMBR (ecological type membrane bioreactor) sewage treatment integration equipment

Abstract

The invention discloses EMBR (ecological type membrane bioreactor) sewage treatment integration equipment which comprises a treatment pond, a sewage inlet pipe, aquatic plants, activated sludge, a mud valve, a membrane component, an aeration head, a planting plate, an air pump and a peristaltic pump. The air pump is connected with the aeration head, and the peristaltic pump is connected with the water outlet of the membrane component through a water outlet pipe; a vacuum sensor is further arranged in the water outlet pipe, the vacuum sensor passes by vacuum trigger circuit used for controlling opening and closing of the peristaltic pump to be connected with the power input end of the peristaltic pump, and a drain pipe connected with the water outlet pipe is further arranged on the peristaltic pump. By the arrangement, integration of the equipment is improved, safety of the membrane component can be better protected during operation of the equipment, service life of the equipment is greatly prolonged, maintenance frequency of the equipment is reduced during use, and use cost of the equipment is further reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an EMBR integrated equipment for sewage treatment. Background technique [0002] Domestic sewage contains a large amount of organic matter and nutrients. If such sewage is directly discharged into natural water bodies without effective treatment, it will not only pollute the environment, endanger human health, but also cause a huge waste of water resources. Membrane bioreactor has the advantages of strong biodegradability, good effluent quality, small footprint, and less residual sludge. However, the existence of membrane fouling severely limits the rapid application of this technology. [0003] The patent document with the application number of 201320354387.1 discloses an ecological membrane bioreactor (EMBR), which organically combines phytoremediation technology and membrane bioreactor technology. By planting aquatic plants in the aeration tank, the traditional membrane bioreac...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned ecological membrane bioreactor has the following problems in the process of use: the air pump and the water pump need to be installed outside the equipment, which greatly affects the aesthetics of the product and is not conducive to the promotion and use of the product; In addition, the water pump adopts the method of continuous water pumping during use, and the water purification capacity of the membrane module is limited. It often happens that the water pipe is emptied by the water pump and the membrane module is damaged under the pressure of vacuum, which greatly shortens the service life of the product and improves product maintenance frequency
