Sewage treatment process taking photosynthetic bacteria as biochemical core

Abstract

The invention discloses a sewage treatment process taking photosynthetic bacteria (PSB for short) as a biochemical core. The technology is as follows: sewage is subjected to a pretreatment / pretreatment process; inoculating a treatment method taking photosynthetic bacteria as a biochemical core; a photosynthetic bacterium biochemical device is specially designed, configured and controlled to operate; the unique growth characteristics (two metabolic pathways of light energy metabolism and oxidative metabolism) of photosynthetic bacteria are utilized to implement growth and proliferation of the bacteria, and the organic pollutants in the sewage are absorbed, converted and degraded by forming advantageous photosynthetic bacteria groups, thereby finally achieving the goal of sewage purificationtreatment.

Description

technical field [0001] The present invention explains a treatment method that uses photosynthetic bacteria as the core biochemistry in sewage treatment, especially relates to a sewage purification treatment method that uses organic pollutant components as the main pollutant and has a high concentration of organic pollutants, such as citric acid, Organic sewage discharged during the production process of sugar, alcohol, paper, farming, leather and other related industries. The core of the process is to use the unique light energy metabolism and oxidative metabolism of photosynthetic bacteria to self-adjust and switch metabolic pathways under two different growth conditions to efficiently absorb, transform and decompose organic matter in sewage , maintain stable life activities, realize the growth and value-added of photosynthetic bacteria, and at the same time degrade the pollutants, so as to achieve the purpose of pollution control. Background technique [0002] Organic was...

Problems solved by technology

Due to the complex composition of organic matter, a single biochemical treatment cannot solve the pollution requirements. In conventional processes, aerobic processes or combined processes are often used. However, no matter what kind of biochemical form, it is implemented and controlled according to the characteristics of the microbial activity that plays a leading role in the process. It is determined that different conventional biochemical process units must be constructed and controlled independently, resulting in high pollution control costs, among which the cost ratio of dissolved oxygen in the aerobic biochemical process is the highest

It has added a heavy cost burden to enterprises and society, inhibited the enthusiasm of enterprises for environmental governance, and caused many mere formal environmental governance cases, which have become serious obstacles to restricting the effectiveness of pollution control and promoting the development of pollution control.
