Abstract

The invention relates to a method for utilizing advanced oxidation for carrying out pretreatment on sewage and culturing engineering microalgae for carrying out sewage deep treatment and carbon dioxide emission reduction. The method utilizes the advanced oxidation for carrying out pretreatment on the sewage and flue gas and utilizes the artificially cultured engineering microalgae for simultaneously solving the sewage deep treatment and the CO2 emission reduction. The method solves the defects that algae in the prior art can not absorb macromolecular organic pollutants in the sewage and is limited in sewage treatment. The method utilizes the advanced oxidation for treating the sewage and the flue gas, then utilizes the engineering microalgae for carrying out the deep treatment on the sewage after the pretreatment in a bioreactor and absorbs CO2 in the flue gas for utilization, and the engineering microalgae can also extract functional products. The method has the advantages of low cost, small investment, high efficiency and good treatment effect, and can carry out resource recovery on the flue gas, increase biomass energy sources, reduce the burden of the sewage deep treatment technology, reduce the project cost and change the sewage treatment concept on the traditional sense.

Description

technical field

[0001] The invention relates to pretreatment of sewage and flue gas by advanced oxidation, and uses artificial cultivation of engineering microalgae to simultaneously solve the advanced treatment of sewage and CO 2 ways to reduce emissions. Background technique

[0002] At present, engineering microalgae is used to treat sewage. Due to the large amount of toxic and harmful organic substances in the sewage, the engineered microalgae has low vigor, low fecundity and low pollutant removal rate, and the engineered microalgae can only absorb CO in the flue gas. 2 , for SO 2 And gaseous nitrogen oxides can do nothing. Therefore, the application of engineered microalgae in environmental governance engineering is limited. Contents of the invention

[0003] The present invention aims to solve the problem of low vitality, low fecundity and low pollutant removal rate of engineering microalgae in the process of using engineering microalgae to treat sewage, and engin...
