Effect of dephosphorizing bacteria on microbial oxidation

There is a kind of "phosphorus rich bacteria" in high phosphorus wastewater sludge. Under aerobic conditions, such phosphorus rich bacteria can absorb excess phosphorus beyond their physiological needs and phosphorus content. Up to 6% - 8% of the stem cells weigh or more, but under anaerobic conditions, this excess phosphorus can be released. The microbiological principle and technology of microbial phosphorus removal therapy is to use the characteristics of phosphorus storing bacteria to absorb and release phosphorus under aerobic and anaerobic conditions, and control the phosphorus removal process under aerobic and anaerobic conditions.

Effect of dephosphorizingbacteria on microbial oxidation

1. Oxidation method is effective for removing high phosphorus wastewater and other high organic wastewater, and is relatively safe for the environment, but the wastewater contains a lot of organic substances. It contains anti biodegradable organic pollutant molecules, which can reduce the therapeutic effect of microorganisms.

2. The deoxidizer can be added to the aeration tank to absorb and precipitate the refractory materials in the water, reduce the sludge load, and improve the removal rate of phosphoric acid in the biochemical system. The chemical oxygen demand (COD) phosphorus removal has an impact on the removal rate and decolorization rate of the phosphorus remover.

3. Since the phosphate in wastewater is removed by aerobic microbial oxidation after phosphorus removal, the degradation rate can be accelerated by reaction due to the coagulation effect of phosphorus removal on wastewater. The electron acceptor has a neutral effect and can convert high price into low cost electron acceptor.

4. Realize the purpose of stimulating aerobic microorganism reproduction. There are many aerobic bacteria in the activated sludge after phosphorus removal by phosphorus remover. Aerobic bacteria are the main food source of microorganisms, and organic pollutants are rapidly oxidized and degraded to achieve phosphorus removal.
