Novel ultramicro separation integrated equipment

Abstract

The invention discloses novel ultramicro separation integrated equipment, which comprises a flocculation reaction area, a microbubble generating device, an ultramicro purification reaction area, and a discharge area.The flocculation reaction area is used for carrying out flocculation purification treatment on sewage; the microbubble generating device is used for generating a gas-water mixture, and the gas-water mixture is mixed with the sewage subjected to flocculation purification treatment to form a gas-water mixed solution; the ultramicro purification reaction area comprises a muddy water storage unit, a water distribution unit, an efficient separation unit and a skimming unit which are distributed from bottom to top, and the water distribution unit uniformly discharges gas-water mixed liquid into the efficient separation unit; micro-particle suspended solids in the gas-water mixed liquid rise to the liquid level through the efficient separation unit, and large-size particle suspended solids are gravitationally settled to the muddy water storage unit through the interception effect of the efficient separation unit; the skimming unit is used for skimming small-particle suspended matters accumulated on the liquid level; and the discharge area comprises a sludge tank and a water outlet tank, the sludge tank receives waste residues discharged by the skimming unit, and the water outlet tank receives produced water discharged by the efficient separation unit. The equipment is high in integration level, high in surface load, small in occupied area and high in purification efficiency.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a novel ultramicro separation integrated equipment. Background technique [0002] Emergency treatment of black and odorous water bodies is an important way to quickly eliminate black and odorous water bodies. The problem of black and odorous urban rivers has become one of the problems faced in the process of environmental governance in my country. Actively developing emergency treatment technologies for black and odorous water bodies is of great significance to the governance of urban black and odorous rivers in my country. [0003] At present, more mature black and odorous water emergency treatment technologies include coagulation and sedimentation, MBR membrane bioreactor, air flotation machine, etc. From the comparison of various technical characteristics, it can be seen that in the case of treating black and odorous water of the same scale, the coagulatio...

AI Technical Summary

Problems solved by technology

The surface load of the existing air flotation machine is generally 5-8m 3 / m 2 h, the load is low and the floor area is too large. When dealing with polluted water, water quality changes have a great impact on the treatment effect of the air flotation machine, and the air flotation machine has uneven distribution of microbubbles, resulting in incomplete sewage treatment. The internal area of ​​the air flotation machine is not sufficiently purified
