Abstract
The utility model relates to a sewage treatment device. The device comprises a water inlet pump, a liquid level controller, a membrane component, a bioreactor, a blast blower, an aeration head, a water outlet pump and a time relay, wherein the bioreactor is a cylindrical container, the membrane component is fixed in the bioreactor, and the aeration head connected with the blast blower is arranged below the membrane component. Activated sludge cultured beforehand is added into the bioreactor, then the water inlet pump is opened to pump sewage to be treated into the bioreactor, and the sewage is filtered by the membrane component under the pumping action of the water outlet pump to obtain effluent water after the microbial degradation of the sewage in the bioreactor.
Description
Technical field
The utility model relates to a kind of waste disposal plant, and this device employing membrane separation technique and activated sludge process combine and carry out sewage disposal.
Background technology
The traditional aerobic biological treatment process that with the activated sludge process is representative has been brought into play vital role for a long time in sanitary sewage disposal and Industrial Wastewater Treatment.But, therefore produced the problem of following several respects because traditional activated sludge process adopts the main means of gravity type boat davit precipitation as mud-water separation:
(1) is difficult to keep higher sludge concentration in the aeration tank;
(2) contain suspended solids in the water outlet, effluent quality is not high;
(3) in the aeration tank, easily produce problems such as sludge bulking, mud come-up, effluent quality instability;
(4) hydraulic detention time and sludge age interdepend, and improve volumetric loading and reduce sludge loading contradiction;
(5) surplus sludge volume is big, sludge disposal expense height.
Because the shortcoming of traditional activated sludge process, people are to the improving constantly of water quality requirement in addition, and various sewage disposal technologies novel and improvement just arise at the historic moment.Wherein, membrane separation technique, particularly membrane bioreactor (Membrane Bioreactor is called for short MBR) combination process is especially noticeable in Application of Sewage.This technology is compared with traditional waste water treatment process and is had the following advantages:
(1) can carry out solid-liquid separation efficiently, separating effect is better than traditional settling tank far away, and effluent quality is good, goes out water suspension and turbidity and approaches zero, can direct reuse, realized sewage recycling;
(2) effect of efficiently damming of film is dammed in reactor microorganism fully, has realized separating fully of the reactor waterpower residence time (HRT) and sludge age (SRT), makes operation control more stable;
(3) the microorganism concn height in the membrane bioreactor, anti impulsion load;
(4) crown_interception of film can prolong the rate of propagation residence time of microorganism (as nitrobacteria) in reactor slowly, helps improving system's nitrification efficiency.Simultaneously, can also prolong the residence time of microorganism in system of some hardly degraded organic substances of degrading, help improving the degradation efficiency of hardly degraded organic substance;
(5) excess sludge production is low, and the sludge treatment expense is few.
Summary of the invention
The object of the present invention is to provide the low sewage treatment process of a kind of energy consumption, this technology has the technical process weak point, takes up an area of and economize, be easy to realize advantages such as control and convenient operation and management automatically.
Technical scheme of the present invention is:
A kind of waste disposal plant, this device comprises: intake pump, fluid level controller, membrane module, bio-reactor, gas blower, aeration head, go out the water pump and the time relay, this bio-reactor is a cylindrical vessel, membrane module is fixed in the bio-reactor, the aeration head that is connected with gas blower is arranged under the described membrane module, in this bio-reactor, add prior cultured active sludge, open intake pump then pending sewage suction is entered bio-reactor, described bio-reactor adopts from the mode of bottom water inlet, control the start-stop of intake pump to keep the liquid level of described bio-reactor by fluid level controller, thereby guarantee that described membrane module is submerged in the sewage all the time, sewage in bio-reactor in active sludge after the microbiological deterioration, obtain water outlet going out under the suction function of water pump to filter by described membrane module, for delaying the film pollution and guaranteeing certain producing water ratio, going out water pump is controlled by the time relay, adopt the operating method of intermittent suction, be the pollution situation of monitoring membrane module, can going out U type differential manometer of installation on water pump and the pipeline that membrane module is connected.
Described membrane module is hyperfiltration membrane assembly or micro-filtration membrane module.
