Cyclic AO high nitrogenous organic waste water treatment device based on MBR

Abstract

The invention relates to a water treatment device. The invention provides a cyclic AO high nitrogenous organic waste water treatment device based on an MBR. The cyclic AO high nitrogenous organic waste water treatment device based on the MBR comprises a reactor with a water storage cavity and a control device, wherein the reactor is connected with a water inlet device, an aeration device and a membrane water outlet device, a membrane biological reactor is arranged in the water storage cavity of the reactor, the water feeding device comprises a water inlet pope, the aeration device comprises an aeration pipe, the MBR is suspended above the water inlet pipe, the MBR is suspended above the aeration pipe, the MBR is connected with the membrane water outlet device, and the water inlet device, the aeration device and the membrane water outlet device are respectively connected with the control device. The cyclic AO high nitrogenous organic waste water treatment device based on the MBR has the beneficial effects that aeration rate is reduced, less sludge is discharged, control is simple, and daily maintenance management is simple, so that water quality is guaranteed; the MBR is not polluted easily, cost is low, occupying area is small, and maintenance is convenient.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an MBR-based circulation type AO high nitrogen-containing organic wastewater treatment device in the water treatment device. Background technique [0002] With the increase of my country's urban population and the expansion of urban scale, the treatment devices for high ammonia nitrogen organic wastewater (such as landfill leachate, low C / N ratio sewage, etc.) have become an urgent technical demand in the current environmental field. At present, the wastewater denitrification process is mainly a biological denitrification process, which mainly includes two stages of aerobic (Anoxic) nitrification and anoxic (Oxic) denitrification. Due to the insufficient carbon source of wastewater and the limitation of microorganisms, it is difficult to guarantee the denitrification effect. The denitrification rate of the traditional biological denitrification process is mainly limited by the concent...

AI Technical Summary

Problems solved by technology

However, the traditional MBR has the following problems: 1. The aeration intensity is very high, and the energy consumption is high; 2. Regular sludge discharge makes it difficult to dispose of the remaining sludge; 3. The process control is cumbersome, and daily maintenance and management are difficult, making it difficult to guarantee the quality of the effluent water; 4. The membrane is easy to foul

In summary, the above sewage treatment processes have problems such as cumbersome process control and complicated maintenance and management, which makes it difficult to guarantee the quality of effluent water from the system, and there are problems such as high investment and operation costs, and large land occupation.
