Abstract
The invention relates to a composite HMBR combine processing method and a device thereof. The method includes that sewage enters a reactor from a water inlet pipe (1) and then enters a reaction zone from the bottom of a water inlet clapboard (2-A); gas enters an aerobic reaction zone to react from an aeration head (5) by a pneumatic pump (3) under the control of a gas flow meter; 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 (10) 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 the 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 omits 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'.

(5) mud that adheres on active sludge 6 and the semi soft packing 7 in sewage and the pond fully contacts, and organism is adsorbed degraded in the water;
(6) the muddy water mixed solution local turbulent flow that flow deflector 8 at 45 produces at the bottom of by the right dividing plate 2-B and pond is constantly washed away film at the pond internal recycle and is set up 9;
(7) sewage after being cleaned utilizes peristaltic pump 10 to set up 9 by film under the control of liquid meter 11 to extract out from reactor and obtain advanced treatment simultaneously.
Described combination treatment method for combined HMBR, the dividing plate 2-B of the water inlet dividing plate 2-A of step (2) and step (6) uprightly is fixed in the Aerobic Pond.
A kind of combined HMBR combined treatment device, comprise water inlet pipe 1, dividing plate 2-A, dividing plate 2-B, air lift pump 3, weather gage 4, aeration head 5, semi soft packing 7, flow deflector 8, film establishment 9, peristaltic pump 10, liquid meter 11, dividing plate 2-B and flow deflector 8 can produce local muddy water turbulent flow and constantly wash away the film establishment that is placed in the pond when aeration.
Described combined HMBR combined treatment device, hollow-fibre membrane or flat sheet membrane are selected in film establishment 9 for use.
Described combined HMBR combined treatment device, described hollow-fibre membrane or flat sheet membrane should uprightly be fixed in the Aerobic Pond.
The present invention reasonably increases dividing plate and flow deflector under size that does not change Aerobic Pond and treatment effect situation, make the sewage of regional area produce turbulent flow simultaneously at aeration, constantly washes away the film that is placed in the Aerobic Pond and sets up.The present technique invention can reduce conventional composite formula HMBR and be used for washing away the aeration head that film is set up setting, reduces the energy dissipation of combined HMBR in practical engineering application when efficient is removed by not change system, has realized the target of " energy-saving and emission-reduction ".
