Description

Solar Photovoltaic Auxiliary Sewage Using Bioreactor Combined with Capacitive Deionization Device processing system

This creation system provides an integrated sewage treatment system, especially a solar photovoltaic auxiliary wastewater and sewage treatment integrated system, which combines biological treatment technology and the technology of using capacitive deionization device, and uses the voltage switching of capacitive deionization to achieve electric charge in sewage. The recycling and reuse of materials, and the use of renewable energy as the energy supply of the system, is a packaged processing system with sustainable utilization of energy resources.

Generally speaking, for the treatment of waste water and sewage, the method of adding chemicals is mainly used to treat domestic waste water and sewage and industrial waste water and sewage, mainly to separate solid pollutants in waste water and sewage to reduce water pollution. The organic pollutants and nutrient-rich mainly nitrogen and phosphorus compounds, and reduce harmful and waste substances in wastewater and sewage, and the wastewater and sewage must go through multiple filtration and purification before it can achieve the effect of water purification.

In a broad sense, wastewater and sewage treatment includes the purification treatment of industrial wastewater, urban sewage, domestic sewage, etc., while sewage basically refers to water containing pollutants produced outside the industry, such as domestic sewage produced in ordinary daily life. , and wastewater refers to the water containing pollutants generated in the process of manufacturing, operation, natural resource development industry or in the operating environment, such as industrial wastewater and agricultural wastewater, while animal husbandry belongs to industrial manufacturing and operation. In most of the treatment process, a part of industrial wastewater containing organic pollutants and nutrient-rich will be treated by the water resource recycling center for secondary treatment to reduce the discharge of organic pollutants, while the typical domestic sewage treatment plant (water Resource recovery center) often includes primary and secondary treatment processes. Sewage enters the treatment plant through underground pipelines, and is filtered by grilles to remove larger solids, such as sediment, paper, plastic, etc., and then enters the first-stage sedimentation. Pool (called pre-sedimentation tank, first-sedimentation tank), the sewage stays in the pre-sedimentation tank for several hours, and after the solid pollutants settle in it, it enters the secondary biochemical treatment reaction tank, basically, in the secondary reaction tank Different treatment methods are used. The secondary reaction tank can be an aerobic aeration tank, or an anaerobic biological filter (trickling filter), etc. Generally speaking, a large amount of air is introduced into the aeration tank to promote The growth of aerobic bacteria, the bacteria feed on organic pollutants and nutrients in the water during the growth process to achieve the effect of water purification. After a large number of bacteria grow, a sludge-like suspension is formed. At this time, the sewage is introduced into the second-stage sedimentation tank, and the sludge mainly composed of bacteria and other microorganisms is settled. In general, the second-level sewage treatment plant with a larger scale can achieve a level similar to that of clean water in terms of sight and smell after the treated sewage. However, according to different water quality requirements, the sewage can be further introduced into the tertiary treatment procedures, such as filtration, coagulation and sedimentation, ion exchange, activated carbon adsorption, reverse osmosis, biological nitrogen removal and phosphorus removal, etc., in order to improve the effluent quality. Sewage is reused, but the process of primary to tertiary treatment is too long, and the cost of consumption also increases.

The wastewater and sewage after entering the bioreactor are degraded to remove most of the organic substances in the water, and then the mud and water are separated by solid-liquid separation, and then the residual water is charged and adsorbed through a capacitive deionization (CDI) device. The ions are removed again, and finally, the pathogenic microorganisms in the water are eliminated after disinfection, so as to achieve the ability of wastewater and sewage purification and water resource regeneration.
