A micron-scale dissolved air flotation sewage treatment equipment

Abstract

The invention discloses micron-scale dissolved gas air floatation sewage treatment equipment comprising a water pump, a compressed air energy storage distributor, a dissolved gas cylinder, a dissolved gas water pressure-sharing energy storage pipe and a reaction tank body, wherein at least one group of micro bubble generators is fixedly arranged in the dissolved gas cylinder; each group of the micro bubble generators is fixed with the dissolved gas cylinder by virtue of a micro bubble generator base matched with the group of the micro bubble generators; an air chamber is reserved between the micro bubble generators and the micro bubble generator base; each micro bubble generator is a ceramic sand grain sintered body; a compressed air energy storage device is connected with an air compressor, and is connected with the dissolved gas cylinder by virtue of a compressed air flow guide pipe; and the compressed air flow guide pipe is in one-to-one correspondence with the micro bubble generator base. The equipment disclosed by the invention is low in energy consumption, practical, convenient to maintain, low in fault rate and simple and convenient to operate, and can be widely applied to water treatment of the industries of sewage, wastewater, drinking water, ozone water and aquiculture.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to micron-scale dissolved air flotation sewage treatment equipment. Background technique [0002] The phenomenon of industrial water pollution in our country is very serious, mainly river water pollution; at present, more than 80% of the more than 500 large rivers are polluted to varying degrees, which is caused by the direct discharge of industrial wastewater; More than 40% of the important rivers in big cities in the country, 90% of the rivers are polluted to varying degrees, which poses a great threat and damage to the environmental ecology and the health of residents. [0003] The key to the quality of waste water or sewage treatment is the dissolved air machine, but the dissolved air machines for water treatment equipment currently on the market generally have large bubbles generated during the production process, poor dissolved air flocculation mixing effect, and dissolved air Th...

Problems solved by technology

[0003] The key to the quality of waste water or sewage treatment is the dissolved air machine, but the dissolved air machines for water treatment equipment currently on the market generally have large bubbles generated during the production process, poor dissolved air flocculation mixing effect, and dissolved air The head is easy to block, cannot be backwashed and reused, and the failure rate is high, the maintenance cost is high, the energy consumption is high, the treated industrial wastewater is not up to standard, and the accumulation of time increases the river water pollution.
