Abstract
The invention relates to an integrated domestic sewage treatment plant comprising a regulation tank and a treatment tank. An MBR membrane separation unit is disposed in the treatment tank. The front end of the MBR membrane separation unit is provided with a filtering sieve plate. An aeration apparatus is disposed between the filtering sieve plate and the MBR membrane separation unit. A backwashing apparatus is disposed at the rear end of the MBR membrane separation unit. According to the invention, the aeration apparatus and the backwashing apparatus are disposed at the corresponding positions of the MBR membrane separation unit, wherein the aeration apparatus increases flow disturbance, thereby protecting the MBR membrane from being blocked by sewage; and the backwashing apparatus can backwardly wash the MBR membrane separation unit after the MBR membrane separation unit is used for a long time, thereby further ensuring service lifetime of the MBR membrane.
Description
Technical field
The present invention relates to a kind of integral life sewage treatment unit, belong to the environmental protection machinery technical field.
Background technology
The integral life sewage treatment unit be suitable for sanitary sewages such as residential quarters, village, villages and small towns, office building, market, hotel, restaurant, sanatorium, office, school, army, hospital, motorway, railway, factory, mine, tourist attraction and similarly butcher with it, processing and the reuse of middle-size and small-size technical scale organic waste water such as processing of aquatic products, food.Through the sewage of this device processes, water quality reaches country's discharging.
The MBR film separation unit possesses good separating effect as a kind of novel membrane sepn medium, uses very extensively in waste disposal plant, but the long-time back of using easily stops up, and need replacing, but its cost is higher relatively, need further be improved.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of integral life sewage treatment unit that can make the MBR film separation unit possess good use properties.
The technical solution used in the present invention is for this reason: the present invention includes equalizing tank, treating pond, establish the MBR film separation unit in the treating pond, MBR film separation unit front end is established the filtration sieve plate, filters between sieve plate and the MBR film separation unit and establishes aerating apparatus, and back-purge system is established in the rear end of MBR film separation unit.
Described sieve plate unit, MBR film separation unit are arranged on the rear end for the treatment of pond, vertically arrange.
Described MBR film separation unit rear end lower is established division board, and division board is divided into flocculation agent.
Advantage of the present invention is: the present invention establishes aerating apparatus and back-purge system at the correspondence position of MBR film separation unit, and aerating apparatus increases the disturbance of current, makes dirt be difficult for the MBR film is stopped up; The application of back-purge system is simultaneously carried out back flushing after the MBR film separation unit uses the long period, further guaranteed the work-ing life of MBR film.
Description of drawings
Fig. 1 is structural representation of the present invention.
1 is that equalizing tank, 2 is that treating pond, 3 is that sieve plate, 4 is that MBR film separation unit, 5 is that division board, 6 is that aerating apparatus, 7 is back-purge system among the figure.
Embodiment
The present invention includes equalizing tank 1, treating pond 2, establish MBR film separation unit 4 in the treating pond 2, MBR film separation unit 4 front ends are established and are filtered sieve plate 3, filter between sieve plate 3 and the MBR film separation unit 4 and establish aerating apparatus 6, and back-purge system 7 is established in the rear end of MBR film separation unit 4.
Described sieve plate Unit 3, MBR film separation unit 4 are arranged on the rear end for the treatment of pond 2, vertically arrange.
Described MBR film separation unit 4 rear end lower are established division board 5, and division board 5 is divided into flocculation agent.
When the present invention works, at first aerating apparatus 6 work, the disturbance that increases current; After dirt separation finishes, open 7 pairs of MBR film separation units 4 of back-purge system and wash, guaranteed the use properties of MBR film separation unit 4.
The present invention arranges sieve plate 3 at MBR film separation unit 4 front ends, can filter big dirt, alleviates the burden of MBR film separation unit 4.
Sieve plate of the present invention Unit 3, MBR film separation unit 4 are arranged on treating pond 2 rear ends, vertically arrange, and after dirt enters treating pond like this, bottom bigger dirt can be deposited at the bottom of the pond, alleviate the burden of sieve plate Unit 3, MBR film separation unit 4.
MBR film separation unit 4 rear end lower of the present invention are established division board 5, and division board 5 is divided into flocculation agent, and little dirt can enter the bottom by division board 5, and by the flocculation agent flocculating settling, and the existence of division board 5 makes dirt can not enter top, and regularly cleaning gets final product.
Claims (3)
1. the integral life sewage treatment unit is characterized in that, comprises equalizing tank, treating pond, establish the MBR film separation unit in the treating pond, MBR film separation unit front end is established the filtration sieve plate, filters between sieve plate and the MBR film separation unit and establishes aerating apparatus, and back-purge system is established in the rear end of MBR film separation unit.
