Description

Polyacrylamide adds medicine and mixes flocculation device

Technical Field

The utility model relates to a sewage treatment plant specifically is a polyacrylamide adds medicine and mixes flocculation device.

Background

Along with the development of socio-economy in China, the scale of industrial and agricultural production is enlarged. Environmental problems become a prominent problem in today's society, especially in wastewater treatment. The sewage treatment is not good, and the sewage flows transversely, so that the life happiness of people is seriously influenced. The sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. The production sewage comprises industrial sewage, agricultural sewage, medical sewage and the like, and the domestic sewage is sewage generated in daily life and refers to complex mixtures of various forms of inorganic matters and organic matters. Most sewage contains floating and suspended solid particles of a certain size; gels and jellies. Therefore, the sewage is treated, physical sedimentation is treated, and suspended matters in the sewage are coagulated, precipitated and separated by a chemical method. At present, when sewage is treated, a flocculating agent (such as polyacrylamide) is used for flocculating suspended matters, and the use of the flocculating agent is an indispensable auxiliary measure. The mixing effect of the flocculating agent polyacrylamide can directly influence the flocculation and precipitation effects, and finally the water quality of the effluent can be influenced. The addition of the flocculating agent is generally divided into two processes of mixing and flocculating. The mixing method of the polyacrylamide includes water pump mixing, tubular static mixer, mechanical mixing, drop (hydraulic) mixing and the like. The flocculation mode of polyacrylamide comprises folded plate flocculation, grid flocculation, mechanical flocculation and the like. The traditional flocculating agent adding mode needs two sets of equipment for mixing and flocculating, on one hand, the problems of large equipment investment, large occupied area and the like exist, and on the other hand, various mixing and flocculating equipment has certain advantages and disadvantages and is limited by application conditions. The utility model discloses hope to propose a novel polyacrylamide medicine mixing arrangement, thoroughly solve above problem.

Disclosure of Invention

The utility model discloses a solve the equipment that exists in the use of flocculating agent polyacrylamide huge, mix the poor scheduling problem of effect, provide a polyacrylamide adds medicine and mixes flocculating device.

Realize the technical scheme of the utility model, a polyacrylamide adds medicine and mixes flocculation device, including the flocculation basin, the flocculation basin side is equipped with the delivery port, is equipped with the explosive barrel in the flocculation basin, adds explosive barrel upper portion and is equipped with the overflow mouth, flocculation tank bottom wear to establish the inlet tube, the inlet tube with add explosive barrel bottom intercommunication, be equipped with the motor on explosive barrel upper portion, the motor sub-unit connection agitator is equipped with the pencil on one side of the explosive barrel, adds the inside medicine ring canal that is equipped with of explosive barrel, add the pencil and connect and add the medicine ring canal, it has the medicine mouth to open on adding the medicine ring canal.

When using, in sewage upwards got into the medicine bucket through the inlet tube, flocculating agent polyacrylamide then through adding the pencil and adding the medicine ring canal entering medicine bucket, through agitating unit intensive mixing in adding the medicine bucket, then flow into the flocculation basin through the overflow mouth, entering into the sedimentation tank through the delivery port and carrying out processing on next step.

Compared with the prior art, the utility model discloses simple structure, area is little, adds medicine efficient, and flocculation effect is good, should add medicine mixed flocculation device can satisfy the requirement of different water yield, water quality treatment.
