Problems solved by technology

①The electrolytic air flotation method consumes a lot of power and is generally only suitable for small-scale water treatment (3 / h); ②Impeller air flotation method, the diameter of the formed bubbles is large, and the adhesion effect is poor
③The pressurized dissolved air flotation method has complicated process, high management requirements and high power consumption
④Shallow air flotation method, which is widely used at present, has complex structure and high production requirements

Abstract

The invention relates to a molecular state gas floatation clarifier. A coagulant adding opening is formed in the upper end of a reaction region, and an air agitation pipe is arranged in the middle of the reaction region; a baffle is arranged at the bottom of a contact region, a water distribution pipe is arranged at the lower end of the baffle, a releaser is arranged at the upper end of the water distribution pipe, and the upper end of the releaser is communicated with a gas dissolving device; a slag remover track is arranged at the upper end of a gas flotation region, and is provided with a composite slag remover; a center slag collection pipe is arranged at the lower end of the slag remover track; a cable support is arranged at the top of the gas flotation region, and a water collection pipe communicated with a water outlet region is arranged at the bottom of the gas flotation region; and a water outlet weir plate is arranged at the tail end of the water collection pipe, and is arranged in the water outlet region. According to the molecular state gas flotation clarifier, air is dissolved in water in a molecular state, so that the dispersity of molecular-state micro-bubbles in water can be increased, the air can be adhered to alumen ustum particles more sufficiently, and the removal rate for colloids and other micro-suspended solids in wastewater can be improved.

Description

technical field [0001] The invention belongs to the field of environmental engineering water treatment, in particular to a molecular air flotation machine. Background technique [0002] At present, in the treatment of sewage and wastewater, the general attention to the chromaticity of discharged sewage and wastewater is not enough. Chromaticity is due to the existence of colloids (1-100nm) and other fine suspended matter (100-10000nm) in sewage and wastewater. Different sewage and wastewater have their own special colors, which often give people an unpleasant feeling. Although there are clear limit requirements for the chromaticity of external sewage wastewater in relevant national standards, most pollution-producing enterprises focus their energy on chemical oxygen demand, biochemical oxygen demand, ammonia nitrogen, phosphorus, heavy metals and other toxic and harmful substances The removal of chroma is neglected. With the continuous strengthening of the national environ...
