A treatment system for oily industrial wastewater

technical field

The utility model belongs to the field of environmental protection, and in particular relates to an oily industrial wastewater treatment system.

Background technique

With the improvement of people's living standards and the development of industrialization, more and more sewage has appeared. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic substances, including: floating and suspended solid particles of large and small sizes; colloidal and Gel-like diffuser; pure solution. Pollutants mainly include: industrial wastewater discharged without treatment; domestic sewage discharged without treatment; farmland sewage with extensive use of chemical fertilizers, pesticides, and herbicides; industrial waste and domestic garbage piled up by the river; soil erosion; Mine sewage.

At present, there are many methods for sewage treatment of sewage, which can generally be summarized as physical methods, chemical methods and biological methods. Physical method: It mainly uses physical action to separate insoluble substances in sewage, and does not change the chemical properties during the treatment process. Commonly used are gravity separation, centrifugal separation, reverse osmosis, air flotation and so on. The physical method is relatively simple and economical to treat structures, and is used in villages and towns where the water body has a large capacity, strong self-purification ability, and low requirements for sewage treatment; biological method: utilizes the metabolic function of microorganisms to decompose and oxidize dissolved or colloidal organic matter in sewage It is a stable inorganic substance that can purify sewage. Commonly used are activated sludge method and biofilm method. The treatment degree of biological method is higher than that of physical method; chemical method: it is a method of using chemical reaction to treat or recover dissolved or colloidal substances in sewage, and it is mostly used in industrial wastewater. Commonly used are coagulation method, neutralization method, redox method, ion exchange method and so on. The chemical treatment method has good treatment effect and high cost, and is mostly used as the effluent after biochemical treatment for further treatment to improve the quality of the effluent.

The above-mentioned traditional methods have certain defects in specific operations. First, the traditional sewage treatment methods generally have relatively complicated treatment methods, and the treatment process is difficult to operate, which is likely to cause secondary pollution or incomplete treatment of discharge problems, especially oily sewage. Sewage treatment uses too many chemical raw materials, which makes it difficult to recycle the treated sewage; secondly, the traditional treatment method is mostly completed by the unit, and the closed treatment equipment is used continuously, which consumes a lot of energy; thirdly, The excrement finally obtained by traditional sewage treatment equipment still cannot be solved well, and there is still the problem of difficult discharge.

Therefore, the production of an oily industrial wastewater treatment system with simple structure, convenient operation, energy saving and environmental protection, high work and operation efficiency, simple treatment process and method, and comprehensive and diverse treatment methods has broad market prospects.

The initial position of the sheet 22 is located at the bottom of the water channel 19, and it coincides with the inner wall of the drainage treatment pipe 20 to ensure that the water channel 19 does not leak water when it is in the filtering state. When the rotating shaft 10 is rotated, the blocking arc-shaped connecting piece 22 leaves the bottom of the water channel 19 and moves downward. At this time, the bottom opening of the water channel 19 is opened, and the clean water flows into the drainage treatment pipeline 20 and passes through The leaking hole 25 is discharged, and directly flows into the waste discharge bin 30 after discharge, and is recycled through the sewage discharge pipe 9 and the waste water recovery pipe 8 for further treatment.

The product is equipped with multiple valves, which can be manually and automatically adjusted according to the actual flow rate of the water. The speed of each batch of sewage treatment is different. According to the pollution of sewage, the opening and closing of the regulating valve can ensure the accurate operation of the system. This system is a slow processing mode. Although the processing speed is slow, it does not require much power resources. It relies entirely on the water flow to automatically realize the processing, which is energy-saving and environmentally friendly.
