First, grain and oil processing wastewater integrated wastewater treatment equipment introduced grain and oil companies produced mainly from clean water before processing, waste oil washing, washing machines and machining shop floor wash water. Such wastewater complex composition, mainly containing saponins, phospholipids, proteins, oils, pigments and other substances with a high concentration of organic pollutants, oil capacity, impurities, etc., harmful to the environment, the higher the processing difficulty. Because now more commonly used "air floatation and hydrolytic acidification + biological contact oxidation" case of large fluctuations in the water treatment process, refractory organics and more difficult to ensure long-term stability of water quality standards, and therefore need efficient and stable grain and oil studies of wastewater treatment new technology. Green Day environmental protection in line with the existing processing technology and related projects on the basis of experience in the design of an integrated device for grain and oil processing wastewater treatment, the use of "flotation + MBR + Fenton" combination treatment, the treated water to reach the national level emission standards, can direct emissions, and for the long-term water reuse technology space reserved. Second, the integration of grain and oil processing wastewater treatment equipment Scope This equipment is suitable for grain and oil processing wastewater. Third, grain and oil processing wastewater treatment equipment features an integrated device can be arranged on the ground, but also buried. When buried, the upper casing can be used for landscaping, small footprint; 2, high degree of automation equipment, savings in operating costs; 3, light weight and sewage treatment equipment, easy to transport; 4, shock load capacity, water quality stable, less sludge production; 5, easy maintenance management, simple operation, no secondary pollution; 6, anti-corrosion effect is good, the device uses four layer anti-corrosion paint treatment, the service life of up to 10-15 years.
