Integrated sewage treatment equipment for bean product processing sewage treatment

① Fine grid well: the coarse grid removes large sundries and some suspended solids in the bean product sewage, which mainly provides guarantee for the normal operation of subsequent unit power equipment

② Regulating tank: this unit is mainly used to balance water quality and balance water volume, reduce the impact load of peak water volume on subsequent treatment units, greatly reduce the impact of water volume change on treatment effect, reduce the volume of treatment structures, save project operation, and facilitate system automatic control

③ Anaerobic hydrolysis tank: in the treatment process of high concentration soybean product wastewater, anaerobic treatment technology is a key step
The removal efficiency of section I of successful anaerobic hydrolysis can reach more than 50%
Anaerobic biological treatment of wastewater refers to a treatment method that mainly uses anaerobic organisms to degrade organic matter in the absence of free oxygen
In the process of anaerobic biological treatment, complex organic compounds are degraded, transformed into simple and stable small molecular compounds, and release energy at the same time
Most of the energy is in the form of methane (CH4)
In the case of anaerobic digestion, the end products are CH4, CO2 and NH3 (NH4HCO3)

④ Coagulation sedimentation tank: this treatment unit is to put an appropriate amount of coagulant into the water body
After full coagulation and reaction, the micro suspended particles and colloidal particles in the wastewater will agglomerate with each other to form a flocculate with large particles and easy to settle (particle diameter & gt; 20 & mu; m), which will be removed by sedimentation

⑤ Air flotation tank: the working principle of the air flotation device is that under certain conditions, a large amount of air is dissolved in water to form AIR-SOLUBLE water
As the working medium, it is suddenly depressurized and released through the releaser, resulting in a large number of fine bubbles adhering to the & ldquo; Vitrification & rdquo; The floc floats upward, so as to effectively remove pollutants in the water and achieve the purpose of purification

⑥ Contact oxidation tank: aerobic biological treatment of wastewater is a treatment method in which organic matter is degraded mainly by aerobic microorganisms under aerobic conditions
All kinds of organic matter in wastewater are mainly colloidal and dissolved organic matter, which is used as the nutrient source of microorganisms
After a series of biological reactions, these organic substances release energy step by step, and finally stabilize with inorganic substances to achieve harmlessness
