Low-energy-consumption sewage treatment device based on carbon source recovery

Abstract

The invention relates to the technical field of industrial sewage treatment equipment, and discloses a low-energy-consumption sewage treatment device based on carbon source recovery. The low-energy-consumption sewage treatment device comprises a treatment tank, wherein a water inlet is fixedly formed in the top of one side of the outside of the treatment tank; the bottom of an inner cavity of thetreatment tank is fixedly connected with the bottom end of a support frame; one end of a transmission rod is movably sleeved and connected with the top end of the support frame; the other end of the transmission rod penetrates through the inside of a sealing plate, extends to the top of the inner cavity of the treatment tank, and is movably sleeved and connected with the top of the inner cavity ofthe treatment tank. The low-energy-consumption sewage treatment device based on carbon source recovery has the advantages that through the matching of a chemical addition tank and an electromagneticvalve, chemicals can be conveniently and better added into sewage in an inner cavity of the treatment tank, so that the problems that the workload of workers is increased through the manual chemical addition, and the consumption of chemicals cannot be easily mastered are solved; the investment of the sewage treatment device on the chemical cost is reduced; the treatment effect of the low-energy-consumption sewage treatment device on the sewage is improved.

Description

technical field [0001] The invention relates to the technical field of industrial sewage treatment equipment, in particular to a low-energy sewage treatment device based on carbon source recovery. Background technique [0002] Water is the basic need to maintain life and health. Although 71% of the earth is covered by water, fresh water resources are extremely limited. my country is a country with severe drought and water shortage. The total fresh water resources in my country are 2.8 trillion cubic meters rice, which only accounts for 6% of the global water resources. Therefore, the shortage of water resources is the biggest challenge and threat faced by mankind in the 21st century. At present, all countries in the world are actively taking actions to save energy resources. In-depth, as one of the main carriers of emission reduction, urban sewage treatment plants are particularly important in emission reduction work. Under this background, the traditional biological treatment...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a low-energy sewage treatment device based on carbon source recovery, which can automatically and flexibly add neutralizers to sewage, quickly stir to accelerate the neutralization reaction in sewage, and quickly separate sewage from sewage. The advantages of solid and flocculated impurities, simple and quick replacement of activated carbon, and high treatment efficiency for sewage solve the problem that due to the complex composition of pollutants in industrial sewage, there are not only suspended pollution impurities, but also various chemical elements. The acidity and alkalinity of the sewage is higher than that of the normal water source, which makes the water source unable to be reused. If it is directly discharged, it will seriously pollute the water resources in the natural environment. , gradually tends to be saturated, leading to the loss of adsorption capacity, unable to adsorb pollutants in sewage, and the replacement procedure for activated carbon in this equipment is complicated, which reduces the problem of sewage treatment efficiency
