4、 System characteristics 1.
Unique gas distribution mode, uniform distribution, purification efficiency of more than 90%.
A small amount of excess biofilms are removed by filtration and discharged regularly as sludge.
The odor and VOCs are oxidized and decomposed by microorganisms to generate energy in the transformation process, which provides energy for the growth and reproduction of microorganisms, so that the transformation of odor gas substances can continue.

The gas flow and circulating liquid complete the three processes of biological gas-liquid diffusion, liquid-solid diffusion and biological oxidation in the process of passing through the biological packing layer, The microorganisms in the biofilm on the surface of the biological filler take the odor gas as the nutrition.
Click the blue word to focus on quality Build with ingenuity The company mainly produces and sells FRP grating, FRP cover plate, FRP pipe, FRP parts, FRP guardrail, FRP fence, FRP winding septic tank, FRP molded septic tank, FRP oil separator, FRP storage tank, SMC molded water tank, stainless steel water tank, FRP fan, FRP cooling tower, FRP desulfurization tower, FRP purifier FRP cable supports, FRP marker posts, FRP bridges and other FRP products, FRP environmental protection equipment and related derivatives are distributed nationwide, quality assurance and preferential in large quantities.
2、 Process flow Odor gas collection device → pretreatment device → biofiltration device → exhaust fan → discharge up to standard 3、 Process description The odor gas is collected through the pipeline and enters the pretreatment device.

Applicable fields: Treatment of malodorous gases containing hydrogen sulfide, ammonia, mercaptan, sulfide and other odorous gases generated in sewage treatment, garbage treatment, feed processing, fecal treatment, pharmaceutical system and other processes.
The purified gas is led out and discharged by the induced draft fan.
After water washing and humidification, the humidity of the waste gas reaches more than 90%.
Using long-term biological fillers, microorganisms can grow by relying on nutrients in washing solution and odor substances in gas without adding additional nutrients.
The wet gas then enters the biological filtration deodorization device.
The circulating liquid contains fallen biofilms and microorganisms, which are recycled after filtration and replenishment of fresh washing liquid.
The tower body adopts modular structure, which can be constructed on site for easy installation; 4.
Microorganisms in biofilm use inorganic and organic substances in waste gas as carbon source and energy, maintain their life activities by degrading odor substances, and decompose odor substances into odorless substances such as carbon dioxide, water and minerals, Achieve the purpose of purifying odor gas.
Fully automatic control, stable performance, no need for special personnel to operate; 2.
Biofilm has stable ecological conditions, large biomass per unit volume, high biosorption and biological oxidation capacity, strong impact resistance, fast decomposition speed and high efficiency of odor substances; 3.
