Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the waste disposal plant structural representation of the utility model based on active sludge.
Refer to Fig. 1, the waste disposal plant based on active sludge that the utility model provides comprises distribution reservoir 1, anaerobic digester 2 and clean water basin 9, between described distribution reservoir 1 and anaerobic digester 2, by water service pump 12, be connected, wherein, between described anaerobic digester 2 and clean water basin 9, be provided with the first Aerobic Pond 3, the second Aerobic Pond 4, active sludge screening pond 5 and the tube settler 7 that by pipe connecting, are connected successively, in described tube settler 7, be provided with coagulation stirrer 6, the below of described tube settler 7 is provided with sludge thickener 8.
The waste disposal plant based on active sludge that the utility model provides, wherein, described anaerobic digester 2 is provided with stirrer 13 under liquid; Described the first Aerobic Pond 3 and the second Aerobic Pond 4 are provided with pneumatic pump 10 that oxygen enters to there is better aerobic reaction; Described active sludge screening pond 5 is connected to active sludge is carried out to recycle with the first Aerobic Pond 3 by activity sludge reflux pump 14; On described tube settler 7, be provided with dosing pump 11; Described sludge thickener 8 is connected to thickened sludge is carried out to recycle with anaerobic digester 2 by thickened sludge reflux pump 15.
The process of the waste disposal plant based on active sludge that the utility model provides is as follows: sewage enters anaerobic digester 2 by pipe connecting after entering distribution reservoir 1, sewage in anaerobic digester 2 by the biodegradable organic substance decomposing in mud being become to carbonic acid gas by amphimicrobe with anaerobic bacterium, methane and water etc., then enter respectively again the first Aerobic Pond 3 and the second Aerobic Pond 4, two Aerobic Ponds are provided with pneumatic pump 10, for air, enter, thereby make active sludge carry out aerobic repiration, further organic substance decomposing is become to inorganics, right reprocessed sewage enters active sludge screening pond 5 again and carries out mud-water separation, water after separation continues to purify, mud after separation returns to the first Aerobic Pond 3 by activity sludge reflux pump 14, recycle, then, the water after processing is through dosing pump 11 dosings, then enters tube settler 7 after stirring by coagulation stirrer 6, by parallel inclined tube, removes the suspended substance in water.Mud after treatment reduces sludge moisture content by sludge thickener 8, reduces sludge volume, then returns to anaerobic digester 2 by thickened sludge reflux pump 15, makes mud sneak into raw waste water and processes together, in order to avoid contaminate environment.Finally, through the water thoroughly purifying, flow into clean water basin 9, allow water circulation use after purifying, economize on resources.
In sum, the waste disposal plant based on active sludge that the utility model provides, by being used in combination anaerobic pond, Aerobic Pond and active sludge screening pond, thereby effectively removes the organism such as nitrogen in sewage, phosphorus, realizes the object of reusing sewage.Concrete advantage is as follows: 1, the utility model, by anaerobic digester and Aerobic Pond, utilizes anerobe and aerobic bacteria, by the organic matter degradation in sewage, is inorganics; 2, the utility model arranges active sludge screening pond and sludge thickener, makes organism in sewage by microorganism adsorption, decomposition, and sewage is purified; 3, the utility model arranges tube settler, increases desilting area, shortens particles settling distance, improves processing efficiency; 4, the utility model arranges activity sludge reflux pump and thickened sludge reflux pump, and recycle mud is not directly got rid of in order to avoid contaminate environment.
Although the utility model discloses as above with preferred embodiment; so it is not in order to limit the utility model; any those skilled in the art; within not departing from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
