Here is a summary of the characteristics of industrial wastewater zero discharge equipment technology. In fact, the purpose of sewage treatment is to separate and treat pollutants in sewage through international advanced technology, or directly convert sewage into harmless and stable substances, so as to achieve sewage treatment. Purified effect. It can not only prevent the infection of viruses and poisons, but also avoid the appearance of odorous objects, so as to meet the needs of different uses.
It can be divided into physical methods, biological methods or chemical methods or used together in several ways to achieve the purpose of removing harmful substances in sewage. Sewage treatment sites are determined according to the water quality. Sewage treatment can be divided into first, second and third treatments.
The primary treatment of zero discharge treatment of industrial wastewater: only physical treatment is required, sand sedimentation tanks, filters, fences, grease traps and other buildings are used to effectively remove oil slicks and solid suspended solids in the water, so as to adjust the pH value. The effect is to reduce the degree of water corruption. After the primary treatment of sewage, it usually does not meet the discharge standards, so it is usually regarded as the pretreatment stage. It can reduce the burden of subsequent processes and improve efficiency.
The secondary treatment of zero discharge treatment of industrial wastewater: through biological or chemical means, the organic matter in the sewage can be degraded. After the secondary treatment, the water can meet the agricultural irrigation and discharge standards. Therefore, the secondary treatment is the main part of sewage treatment. At this time, there are still some insoluble organic matter and nutrients in the water, which cannot meet the higher discharge standards and cannot be discharged in water with poor dilution capacity.
It can meet the sewage treatment requirements of special industries such as urban sewage, rural sewage, highway service area sewage, and hospitals. However, the method of treating rural domestic sewage is different from the method of treating industrial wastewater and unconventional sewage. Therefore, the quotation and processing technology are different. Urban streets, residential areas, greenery around hotels, road washing, washing and cleaning water for vehicles, service areas, tourist distribution areas, holiday centers and shopping places and other daily sewage treatment and secondary utilization, agricultural planting, viewing water features, River water purification, etc.
The adaptable zero-discharge treatment of industrial wastewater has no special requirements on the environment, land occupation, weather and sewage quality. The floor area can be determined according to the specific needs and circumstances of the user. Due to the integrated design of the equipment, it can be installed centrally or dispersedly to meet user requirements for processing results. It can be installed flexibly according to the actual situation of the owner to reduce land problems.
Fully automatic operation, easy maintenance after normal operation of the equipment, in an effective microbial environment, can effectively complete the purification of sewage treatment, with strong processing capacity. The operation process of the equipment does not require special personnel to look after, because this equipment is less dependent on manpower, so it greatly reduces the possibility of operating errors and unstable operation of the equipment, the probability of failure is very low, making unattended a reality and easy to maintain.
