Meizhou sewage treatment equipment manufacturers of food plant sewage treatment process industrial wastewater treatment ..

Food industry raw material widely, wide range of products, the process uses a large amount of water, so a lot of waste as a form of sewage discharge. Water discharge wastewater, water quality varies greatly. Food factory wastewater main pollutants are: (1) floating solids in the wastewater, such as leaves, fruit, meat, poultry feathers; (2) was suspended substances in wastewater fat, protein, starch, colloidal substances ; (3) was dissolved in the waste water of acids, bases, salts, sugars and the like; (4) Raw material entrained silt and other organic substances; (5) drugs and other pathogens. Features food industry waste is the high content of organic matter and suspended solids, perishable, usually without great toxicity. Its main hazard is to eutrophication, so as to cause the death of aquatic animals and fish, prompting underwater organic matter deposited odor, deterioration of water quality, pollution of the environment. Waste water treatment for food manufacturers, the need is less investment, low operating costs, stable operation, good effect, easy operation and management of the treatment process, Dongguan up environmental protection over the years, the company is implementing the scientific management, innovation and development, honesty trustworthy approach, the maximum meet customer needs. Food industry waste water treatment principles and methods of wastewater treatment in the food industry, rich in organic matter, oxygen is the characteristics of organic wastewater, so the organic wastewater treatment, the use of biochemical methods. Organic food industry sewage into bodies of water, under aerobic bacteria and adequate supply of oxygen, the aerobic decomposition into inorganic substances, the decomposition process is called biological oxidation process. Artificial measures to train microorganisms in water, enter the sufficient oxygen to promote the biochemical process of decomposition of organic matter, which is the essence of aerobic biological treatment method. Aerobic biological treatment of organic wastewater has the following advantages: biochemical reaction speed, simple aerobic digestion equipment is simple, less investment in infrastructure, stable operation. Aerobic treatment process generally applicable to low concentrations of organic wastewater. First, aerobic biological treatment of organic waste are mainly activated sludge, biofilm aeration pond and membrane bioreactor method. Food Industry Sewage treatment: 1, activated sludge: general ordinary activated sludge process wastewater to go through the primary settling tank, previously removed some of the suspended particles in order to reduce the workload of the activated sludge, and waste water entering with vessel or structure, activated sludge aeration device is in the water in this device BOD "eat" and produce a new active sludge. BOD reduced to a certain extent, the treatment of wastewater and the good part of the active sludge flow into the other vessel, the secondary settling tank. Removal of water can be discharged after the activated sludge. Since the sludge aeration tank constantly being taken away, it also needs to be part of the return sludge aeration tank, in order to maintain the concentration of activated sludge aeration tank. Food Industry Sewage treatment: 2, biofilm: bacteria and other microorganisms to grow in a thin film solid filler surface to form biofilms. Biofilm general was fluffy floc structure, microporous, large surface area, has a strong adsorption capacity. When the fluid in the solid filter upstream obsolete biofilm adsorbed organic matter is degraded and removed. Food Industry Sewage treatment: 3, aeration pond method: aeration pond is a large surface area and shallow depth of earthen ponds, with a surface aerator and oxygen are mixed, the soluble to insoluble organic matter into microbial cells, it Easy running operation, waste water simply flows out from the other side, especially in the less attractive operating costs from one place to enter. Food Industry Sewage treatment: 4, membrane bioreactor method: membrane bioreactor is a biological wastewater treatment and physicochemical treatment in a pool completed, biochemical degradation of organic matter, porosity ≤0.4μm membrane filtration stage solid-liquid separation, greatly improving muddy water separation efficiency, and effects due to an increase in water and sludge bacteria in activated sludge aeration tank appear to improve the rate of biochemical reactions. This process can greatly reduce the production of excess sludge, treated effluent water is crystal clear, water quality is much better than other sewage treatment process. Second, anaerobic biological treatment of wastewater when higher concentration of organic matter, microbes thrive, consume large amounts of oxygen, for such a high concentration of organic wastewater (general COD2000mg / L or more), generally the first anaerobic treatment, BOD reducing aerobic treatment before use. Anaerobic biological treatment under anaerobic conditions, with the decomposition process of organic matter anaerobic (facultative) microorganisms conducted. Most anaerobic treatment process using sludge return mode. Features 1, food sewage treatment equipment and technology improve, mature technology, large capacity, functional and reliable, small footprint, reduced investment costs. 2, the high degree of automation equipment, processes and equipment structure is simple, easy to use, no special duty, only regular maintenance on equipment and accessories. 3, equipment operation and stability, high efficiency, can eliminate bulking. 4, the device is not to limit the amount of sewage, flexible, can be used individually, but also several joint use for post expansion, raise the standard for the convenience. 5. The system produces less sludge equipment, to avoid the transfer of pollution, save operating costs and processing costs of sludge. 6, the device saves the area, you can choose to be buried according to the scene, half-buried layout. Up Environmental Protection Technology Co., Ltd. Service: After the equipment is completed, the company in accordance with the requirements of the equipment contract freight to the customer's location, and send our professional engineers to the project site is responsible for directing the installation, the installation is completed, commissioning until the discharge is completed. After completion equipment we offer one year warranty for normal operation. Warranty services provide users with free technical support, engineering and maintenance after the warranty expires and equipment maintenance and other services, only the fees. During the warranty period, the equipment operation and management staff can not be excluded in case of failure, after receiving customer fault notification, I will give emergency plan within two hours, the province within 24 hours (48 hours outside) personnel arrived at the scene of the fault processing. In the free warranty period, we regularly visit, assist device operation management personnel to do device management. After completion of the project to the user's operation of our technical training, including device processing system works, process, routine procedures, common troubleshooting, etc., until the church so far. Ensure that the company's leading position in the industry and competitive advantage. Dare to challenge and sustainable development. Is a professional equipment manufacturing company, has the ability on the basis of development and design to provide you with the best quality products and services.
