Industrial wastewater treatment equipment, mainly for power plants, steel mills, chemical plants and other large industrial and mining production process of sewage treatment. Targeted according to the different characteristics of wastewater treatment. The main treatment process flocculation, precipitation, acid-base neutralization, biological treatment, sterilization treatment. Water can meet the national emission standards for reprocessing or reuse standards. Industrial waste refers to waste water, sewage and industrial waste generated in the process, with water containing pollutants loss of industrial production materials, intermediates and products, and the production process produces. Industrial waste is usually divided into the following three: The first one is based on the main pollutants in industrial wastewater containing chemical nature classification, including inorganic contaminants based inorganic waste water, containing mainly for organic wastewater contaminants. Such as wastewater electroplating wastewater and mineral processing, and inorganic waste water; food or waste oil processing is organic waste. The second is based on product and process industrial enterprise object class, such as metallurgy wastewater, wastewater, waste gas coking coal, metal pickling wastewater, wastewater chemical fertilizer, textile printing and dyeing wastewater, dye wastewater, wastewater, wastewater, power plant waste and so on. The third is the main component contained by the wastewater pollutants classified as acidic waste water, alkaline water, wastewater containing cyanide, chromium-containing wastewater, wastewater containing cadmium, mercury-containing waste water, wastewater, wastewater containing formaldehyde, oily wastewater sulfur-containing waste water, waste water and radioactive phosphorus-containing wastewater. Electroplating wastewater treatment technologies and processes described a water source: the commonly used species are nickel plated, copper plated, lead, silver, gold and tin. Whether plating plating, electroplating process much the same. In the electroplating process, after degreasing, acid and electroplating operations, are cleaned with water, electroplating wastewater from electroplating process plating cleaning, bath filtration, waste bath and running due to improper operation management, risk , drip, leak. Second, electroplating wastewater treatment: Common chemical, ion exchange, electrolysis, microbiological method in addition to chromium. Third, the sewage treatment process: different types of plating wastewater can be divided into waste water containing chromium-containing wastewater and other acid waste categories. Here is our common chemical electroplating wastewater treatment processes. Dyeing Wastewater Treatment Technology and process description dyeing wastewater composition is more complex, containing a large amount of residual dyes and additives, and therefore large color high organic content, suspended solids and more, and contains trace amounts of toxic substances. According to water quality data and requested its design, the general treatment process pretreatment + physico-chemical treatment + biological treatment. Using patented microporous rubber tube aeration, oxygen utilization increased 4-8 times, based on years of operating experience, combined with professional configuration, so as to achieve low construction cost, operation cost is small, water quality and stability characteristics. Its influent COD by 500-1300mg / 1 meter, water ≤100mg / 1 design. Process: coarse grid wastewater → → → sump pump → cooling tower pump → → → regulating pool → coagulation reaction tank drum sieve primary settling tank → → → contact oxidation pool acid hydrolysis coagulation reaction tank → → secondary sedimentation tank → effluent discharge standards woolen pool wastewater treatment technology and process description is a woolen mill wastewater difficulty of industrial organic wastewater, my company after study concluded, we formed a unique "aerobic hydrolysis acidification coagulation sedimentation" scouring wastewater treatment process that only a small investment, low operating cost, and reliable. Process: coarse grid wastewater → → → sump pump → hydrolysis acidification tank → → an aerobic tank two aerobic tank coagulation sedimentation pond → → → sand filter effluent discharge standards renewable papermaking wastewater treatment technology and process description The row of papermaking wastewater contains large amounts of industrial and domestic waste, sand and other debris, mainly pollution from slag, washing, concentration step, the kinds of waste water with high concentrations of pollutants, suspended solids and many other characteristics. Water quality parameters are: COD = 700-1300mg / L SS = 150-500mg / L color = 150-700 (times) regeneration paper most commonly used treatment in three ways: The first is a biological treatment, but there are large area, high investment costs, operating costs higher shortcomings. The second is physical and chemical treatment, but the water can not be reached. The third is materialized + biochemical process. According to the analysis, recycled paper production waste water pollution comes mainly from about suspended solids, which can be capacitive COD is relatively small, according to its specific characteristics, I generally deal with this kind of wastewater using materialized + biochemical methods.
