Sewage treatment equipment > Zl - ctws001 restaurant wastewater treatment equipment
Restaurant wastewater composition is complex, high organic matter content, mainly food fiber, starch, protein and fat, all kinds of seasoning vegetable oils or animal fat, detergent, etc.Which contain fat and vegetable oil, oil floating on the surface, the influence of air and oxygen exchange for hydrosphere, and oil can be dispersed in water microbial oxidation decomposition, so the rate of oil not only reduce after oxygen, and the dissolved oxygen in the water consumption, water quality deterioration.Catering mainly exists in the form of colloid pollutants in wastewater, low pH, ss value is very high, turbidity is very large, relatively high BOD and COD values.In general, more food and beverage wastewater organic components, comprehensive function between the various components of strong, poor stability, but not toxic, management is relatively difficult, its discharge time has the certain regularity, discharge of instantaneous flow rate is big, noon and night is usually the kitchen sewage discharge peak period.
Company in the domestic and foreign restaurant of sewage disposal plant, on the basis of operating experience, combined with their own scientific research and engineering practice, design a kind of can be set up ground set of organic sewage disposal plant, the equipment used in the late ninety s at home and abroad advanced technology and manufacturing technology, to produce carbon steel corrosion, stainless steel as the main raw material of ZL - ctws001 (1-50 m after) type sewage disposal equipment series. The main purpose is to make the food and beverage wastewater and similar industrial organic wastewater after the equipment management meet the user requirements of discharge standards.

Direct recycling of restaurant wastewater in mechanical bone, removing impurity removing water lettuce leaves even wash with cloth such as large impurity and starch, protein, carbohydrate, detergent and colloidal substances and other impurities.Then the oil-water separation for liquid part.For oily part acid analysis, water washing, waste oil, and to control the amount of acid in the process of acid out of pH between 2-3 is the best.Oil-water separation part of water and water mixed with water after through regulating pond water, the pump up to the coagulation air floatation pool to remove most of the SS, oil and organic matter, and then to biochemical treatment.Biochemical treatment by SBR - method, PACT in biochemical pool dosing powder activated carbon, biochemical treatment effluent standards;After the sludge thickener sludge dewatering treatment.In this process, the handling of food and beverage wastewater consists of preprocessing system and the biochemical treatment system
Processing system: adjust pool and coagulation air floatation pool main stable water quality of water, and remove or reduce the sewage in affect the subsequent biochemical treatment of organic and inorganic substances.Due to the low pH in sewage water quality, belongs to the acidic wastewater, and high oil content here using alkaline neutralization coagulation air flotation.
1. The equipment is buried in the earth's surface, it can be to afforest, beautiful environment.
2. The entire device is generally not need of personnel management.
3. Can reduce cover an area of an area, the equipment can be built above the parking lot, etc., without having to build factories and other facilities.
1. Can be buried under the surface of the earth.
2. The full automatic control, do not need to personnel management.
