Combination treatment method for combined HMBR and device

Abstract

The invention relates to a composite HMBR combine processing method and a device thereof. The method includes that sewage enters a reactor by a water inlet pipe (1) and then enters a reaction zone by the bottom of a water inlet clapboard (2-A); gas enters an aerobic reaction zone to react by a pneumatic pump (3) under the control of a gas flow meter (4) from an aeration head (5); the sewage then completely contacts with active sludge (6) in a pool and the sludge attached to semi-soft fillings (7), and organisms in the water are absorbed and degraded. The mixed solution of sludge and water generates local turbulent flow by a right clapboard (2-B) and a deflector (8) having an angle of 45 degrees with the bottom of the pool to wash a membrane component (9) circularly in the pool; the purified sewage is pumped from the reactor by the membrane component (9) by utilizing a peristaltic pump under the control of a liquid flowmeter (11), and meanwhile the water is treated deeply. By adopting the guide flow of the clapboard (2-B) and a deflector (8) lead the water to generate the turbulent flow in the local zone to continuously wash the membrane component (9), the method of the invention spares an aeration head used for washing the membrane component in the traditional composite HMBR and effectively reduces the operating cost without changing the removal efficiency and realizes the 'energy conservation and emission reduction'.

Description

technical field [0001] The invention belongs to the field of composite membrane sewage treatment, and in particular relates to a composite HMBR combined treatment method and device. Background technique [0002] At present, water pollution is becoming more and more serious. The amount of sewage discharged by all walks of life is increasing significantly and the water quality is becoming more and more complex. Reducing the impact of sewage discharge on the environment and realizing reclaimed water reuse as much as possible are now hot topics for environmental professionals. one. At present, many domestic enterprises or factories use HMBR technology to achieve this goal. [0003] The existing HMBR usually adopts the combination of activated sludge + membrane formation, biofilm method + membrane formation, and composite + membrane formation. Among them, the composite + membrane structure has attracted more and more attention because of its good removal of various indicators o...

Problems solved by technology

like figure 1 As shown, when the membrane is placed in the aerobic tank, it needs to be washed independently by the aeration head to reduce the clogging degree of the membrane by sludge. Most of the aeration heads are only used to wash the membrane to avoid its clogging during work, and it is very easy Less is because of increasing the amount of dissolved oxygen in the pool, so it also causes energy waste in actual engineering
