Description
Technical field
Utility model relates to a kind of water treatment facilities, belongs to chemical technology field.
Background technology
Swash plate/tube settler has solved the spoil disposal problem.Still have a lot of water factories to adopt rectangular sedimentation tank at southern area at present, when rectangular sedimentation tank is transformed, adopt and add swash plate/inclined tube, enforcement is convenient and can improve operating load with the increase of urban water consumption, and be placed on indoor owing to water treatment building in the northern area of China, be subjected to the restriction of floor space, almost all adopt swash plate/tube settler.Can further improve the clearance and the operating load of turbidity to the transformation of swash plate/tube settler by rectangular sedimentation tank, how existing water factory is carried out little transformation thereby existing swash plate/tube settler is improved effluent quality to the removal efficient of turbidity, satisfy higher Drinking Water water standard and have very great economy meaning with further exploitation.Winter low temperature low-cloudy water turbidity removal rate is low, need add a large amount of flocculation aids and coagulant.Because flocculation aid and coagulant need add for a long time, required operating cost height, existing swash plate/tube settler is removed the another timing of ability of suspension in the water, needs to propose a kind of economy and effective solution.The deposition efficiency of sedimentation basin depends on the structure structure in it, and the swash plate spacing directly influences the ability that sedimentation basin is removed flco.
The utility model content
The purpose of utility model is a problem low for the turbidity removal rate that solves existing sloping plate sedimentation tanks, the sedimentation effect difference, and a kind of multilayer inclined-plate clarifying basin of reinforced deposition is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
A kind of multilayer inclined plate sedimentation device of reinforced deposition, described settler comprises sedimentation basin, precipitation parts and support, the precipitation parts are installed in the sedimentation basin by support, the precipitation parts are made of the multilayer swash plate, place three to five layers of precipitation parts that total height is a sedimentation basin height 2/3rds to 3/4ths in the sedimentation basin, every layer of swash plate be arranged in parallel, and the angle of inclination of every layer of swash plate is 40～65 °, and the distance between every layer of swash plate is 35～80mm; The angle of inclination of multilayer swash plate from top to bottom increases; Each swash plate side up is also parallel dispersedly to be provided with a plurality of ribs, and the cross section of swash plate is parallel with the longitudinal cross-section of each rib on it, and the distance between the adjacent rib is 45～50mm.
The beneficial effects of the utility model are:
Utility model is provided with the multilayer swash plate in sedimentation basin, lower floor's swash plate is born the removal of bulky grain suspension, and the upper strata swash plate is born the more removal of the particle suspensions of small particle diameter, thereby the water pollutant clearance is increased.The removal of the particle in the upper strata swash plate of utility model, thus the water pollutant clearance is increased.Utility model has increased the surface area of swash plate, because the colloidal solid thing has taken off the steady particle that forms the bigger level of particle diameter easily when slipping into lower floor's swash plate, can collide mutually with the small particle that current in the lower floor swash plate carry, and forms bigger particle and sinking easily.The method of utility model not only can be more thorough to the pollutant removal in the inclined-plate clarifying basin, also can reduce the dosage of coagulant and flocculation aid.Utility model have cost of investment few, be easy to implement, reliable operation, the advantage that clearance is high.The more conventional sedimentation basin load of the utility model can improve 2.4～2.5 times; Utilize the utility model to handle in the water outlet of sewage the existing sedimentation basin of granule content and obviously reduce, treatment effect obviously improves.In water treatment field, has very wide application prospect.
