Process flow of starch sewage treatment equipment

Starch sewage treatment equipment features:
1, the use of advanced hydrolysis - contact oxidation process.
2, high removal rate of organic pollutants, impact load capacity, water quality and stability.
3, the sludge production is small, the equipment inside the sludge backflow system and sludge digestion system, without the need for another sludge treatment equipment.
4, while both nitrogen and phosphorus removal effect.
5, the main processing equipment for the buried combination, according to the user to provide the site area and the status quo assembled, covering less, easy to green.
6, the choice of low-noise energy-saving blower, low power consumption, gas supply easier to control. The degradation of the biofilm is better.
7, a small investment, low operating costs.
8, the construction is simple, easy to install, easy management.
9, generally do not bear the car load.
10, a number of units in parallel can be combined to form a large-scale sewage treatment plant.
 
Overview of Process Flow of Starch Wastewater Treatment Equipment
According to the characteristics of the sewage treatment works, functions, requirements and sewage discharge characteristics, the use of biochemical A / O + O combination process. To meet the national (GB 18918-2002) in a level A standard. The treatment of domestic sewage, because the sewage in the BOD5 / CODcr about 0.57 or so, is a biochemical wastewater. According to the requirements of sewage discharge, the effluent has the NH3-N limit, so in the choice of sewage treatment process in addition to considering the addition of organic matter, but also taking into account the nitrogen removal, in order to achieve this goal, the selection process is mature, reliable A / O combination process (hypoxia + aerobic + aerobic) process.
Due to the large amount of sewage discharge and emission concentration, and more mechanical impurities, so in the sewage treatment before a set of mechanical grille, to remove large particles of mechanical debris, the grille removed after the sewage into the regulation pool , Adjust the pool to adjust the water and water quality, adjust the pool of sewage from the submersible sewage pump into the post-level A / O biochemical system, A section for the hypoxia section, O section for the aerobic section. The process uses A / O hypoxia, aerobic process combined treatment process, the three sections of the oxidation out of a part of the mixture back to the front of the anoxic tank to achieve the purpose of nitrification and denitrification.
The oxidizing pool wastewater is returned to the inlet side of the anoxic tank at a certain reflux ratio. The anaerobic tank is subjected to micro aeration by air. The denitrifying bacteria in the anoxic tank reduce the chemical composition nitrogen to gaseous nitrogen (N2) Oxygen below 0.5mg / L, facultative denitrifying bacteria use the organic carbon source in the wastewater as the hydrogen donor, the chemical composition and the sub-chemical components from the aerobic tank mixture are reduced to nitrogen into the atmosphere, and the organic matter degradation.
Starch wastewater treatment equipment has the advantages of good treatment effect, stable operation, automatic control, easy operation and management, and has the advantages of strong impact load, less sludge production and significant effect of ammonia removal. Taking into account the odor generated by the system, the odor generated by the treatment system is collected through the pipeline or discharged into the sewer.
Starch sewage treatment equipment using integrated buried processing equipment, steel structure (Q235A material), epoxy coal asphalt corrosion. Treatment scale sewage treatment system processing scale 72m3 / d.
