Description
Technical field
The utility model relates to a kind of waste disposal plant, especially relates to the waste disposal plant of membrane bioreactor and active sludge coupling.
Background technology
The present method of handling waste water has a variety of, can be divided into physics method, chemical method, photosynthetic bacterium method, biological process and electrochemical process.The physics method generally is to dispose of sewage with modes such as filtration, deposition and air supportings, and the general disengaging time of physics method is short, device is simple, treatment capacity is big, but higher to the performance requriements of equipment.Chemical method generally is to add specific reagent; Can deleterious element in the water be handled, have that initial cost is few, technology simple, processing ease, energy consumption are low, it is strong that the variation of temperature is adapted to, but shortcoming is more single; Cost is high, can not handle the complicated high-concentration waste water of content.
The utility model content
The technical problem that will solve of the utility model is that a kind of membrane bioreactor and active sludge coupling waste disposal plant are provided.
For solving the problems of the technologies described above, the technical scheme of the utility model is following:
A kind of membrane bioreactor and active sludge coupling waste disposal plant; Include distribution reservoir and aeration tank; Described distribution reservoir is connected with the aeration tank through water pump, and aeration tank one side is provided with air, on the pipeline of air glass rotameter is set; The right-hand component of aeration tank is provided with liquidometer, and liquidometer is connected to fluid level controller; Described aeration tank is divided into a left side and right two parts, and the left-hand component of aeration tank is active sludge processing system, active sludge processing system by the aeration tank be attached thereto logical settling tank and form; The right-hand component of aeration tank is the Membrane Bioreactor for Wastewater Treatment system, belongs in the aeration tank of Membrane Bioreactor for Wastewater Treatment system the hollow fiber film assembly that is connected with external peristaltic pump is installed, and between peristaltic pump and the hollow fiber film assembly vacuum pressure gauge is installed.
One side of described settling tank has water outlet.
During actual the use, water inlet adopts the artificial distribution to distribution reservoir, be drawn in the bio-reactor cas system through intake pump, and the microbiological degradation of pollutent wherein in active sludge, treat effluent is obtaining after membrane module filters under the negative pressure-pumping effect of peristaltic pump.The liquid level of reactor drum is controlled by fluid level controller, and when water level reached minimum water inlet liquid level, water pump was intake automatically; When water level reaches the highest water inlet liquid level, stop into water; When water level reaches minimum water outlet liquid level, stop water outlet from peristaltic pump; Other states keep normal water outlet down.Air moves continuously, and aeration mode is the continuous aeration mode, for the aeration tank provides competent oxygen.Aeration rate adopts spinner-type flowmeter to regulate.Peristaltic pump is taked the intermittent operation mode, and taking out the time of having a rest is 9min/6min.Filter pressure changing conditions in the vacuum pressure gauge monitoring test process on the hollow-fibre membrane.Mixed solution in the aeration tank after active sludge decomposes overflows to settling tank, through post precipitation, obtains treat effluent from water outlet.Precipitating sludge is back to the aeration tank through the passage or the syphonic effect of dividing plate bottom, utilizes the unlatching of intake pump to come the liquid level in the controlling reactor constant.
Compared with prior art, the beneficial effect of the technical scheme of the utility model with:
The utility model is simple in structure, easy to operate, can carry out two kinds of WWT modes simultaneously, can improve the efficient of WWT.
