Biocleaner Biocleaner biological deodorization profile


1. Technical background

Due to the water treatment process adopted by the sewage treatment plant, there is a large amount of odor every day, which has a bad impact on the daily life of residents around the sewage treatment plant。Now the United States Biocleaner biological deodorization technology is introduced to transform the sewage treatment plant to remove odor。

Second, the cause of odor

The aeration head in the aeration system of the sewage treatment plant is about 5 meters below the water surface, but the effective water depth of the treatment tank of the water treatment plant is about 7 meters。Under the action of microorganisms, a large part of the pollutants in the sewage are converted into organic sludge. After long-term operation of the sewage treatment plant, the organic sludge accumulates at the bottom of the pool of the sewage treatment plant to form a sludge layer。The water at the bottom of the pool is deficient in dissolved oxygen (DO)。The activity of aerobic bacteria decreased, the activity of anaerobic bacteria increased, and the microbial activity at the bottom of the final water treatment pond was mainly anaerobic reaction。

Third, deodorization technology

1. Technical sources

Biocleaner microbial sewage treatment is the use of solidified microorganisms imported from the United States for sewage treatment. Solidified microorganisms are microorganisms selected from nature by BOC company, domesticated and implanted into the carrier。Through the advanced curing cell technology, the microorganisms get special protection in the carrier。BOC is at the leading level of biological treatment technology, with more than 11,000 kinds of microorganisms screened from nature, according to different pollution conditions and treatment requirements in the water body, more than 10 kinds of advantageous combinations of microorganisms selected for specific pollutants into the patented carrier。Once it enters the water body, it can produce a high density of microbial flora, the density of 106/CC, through the continuous production of microorganisms, the pollutants that need to be treated are degraded, and the optimized combination of microorganisms can quickly "eat" the sludge in the sewage through collaborative combat and high energy, and remove the odor。It is suitable for industrial wastewater and domestic sewage, river, lake, river, salt water lake, bay treatment。

2. Introduction of immobilized microorganism technology

Through ion adsorption, embedding, cross-linking, covalent binding and other biological engineering means, the superior combination of microorganisms selected by a variety of specific pollutants are fixed on a multi-enzyme system carrier, so that the microorganisms get special protection on the carrier, a new and revolutionary sewage biochemical treatment technology。

The core of this technology is the extraction and enrichment of pure microorganisms and the carrier bed technology with excellent performance. Through the implantation of carriers, high-density microbial flora can be produced, with a density of up to 20000mg/l, which is 10 times the biological concentration of ordinary activated sludge method。Pollutants flow into the reactor,Carrier bed can ** all sewage that needs to be treated can be in contact with microorganisms,Each carrier particle is only 3/8 inch in diameter,The internal and external surface area of the pores in the microbial carrier is about 2-3 square meters,It can make the microorganisms have a larger space to attach and multiply,Only a small proportion of microorganisms are exposed to high concentrations of toxic chemicals,Most of the microbes are protected,High concentrations of sewage can harm some microorganisms,The inner layer protection of the carrier makes the inner layer microorganisms not affected by the impact,repropagation,Replenish the amount of microbial loss。

4. Technical principles

Through the operation of Biocleaner device, biofilm is formed in the water treatment pool, and the malodorous gas is converted into CO2, H2O, SO42- and NO3- by the metabolic action of microorganisms And other inorganic substances to purify odor gases。
