四。皮革废水处理(Leather wastewater treatment)
Tannery wastewater can be treated by biochemical method. However, the wastewater often contains sulfide and chromium ions, which can inhibit microorganisms, so we should pay full attention to the role of pretreatment, so in the treatment of tannery wastewater, the combination process of "physicochemical + biochemical" is generally used. The COD of tannery wastewater is generally 3000-4000 mg / L, which has good biochemical property. After the wastewater treatment process, the effluent generally meets the national discharge standard.
五。电镀废水处理装置(Electroplating wastewater treatment unit)
The electroplating wastewater treatment adopts the iron chip internal electrolysis treatment process, which mainly uses the activated industrial scrap iron to purify the wastewater. When the wastewater contacts with the filler, there are electrochemical reaction, chemical reaction and physical action, including catalysis, oxidation, reduction, replacement, CO sedimentation, flocculation, adsorption and other comprehensive action, which can remove all kinds of metal ions in the wastewater and make the wastewater get Purify.
六。印染废水处理装置(Printing and dyeing wastewater treatment unit)
Printing and dyeing wastewater mainly contains dyes, pulp, dyeing auxiliaries, fiber impurities, oil agents, acids, alkalis and inorganic salts, which is recognized as one of the most difficult to treat. Coagulation treatment of printing and dyeing wastewater has the advantages of good treatment effect and low cost, so it has become an important means of industrial wastewater treatment.
Membrane separation technology is a new type of efficient and environmental protection separation technology. In recent years, with the continuous development and progress of membrane separation technology in China, modern high-tech membrane separation technology (mainly ultrafiltration, nanofiltration and reverse osmosis technology) has been widely and successfully applied in the printing and dyeing industry, and has produced good economic and social benefits.
七。化工废水处理厂(Chemical wastewater treatment plant)
Chemical waste water refers to the waste water produced in the production process of chemical plant products, such as the oily waste water from the production of ethylene, polyethylene, rubber, polyester, methanol, glycol, oil tank area, air separation and air compression station and other devices. After biochemical treatment, it can generally reach the national secondary discharge standard. Now, due to the shortage of water resources, the water that meets the discharge standard needs to be further treated After treatment, meet the requirements of industrial water supply and reuse.
八。陶瓷废水处理厂(Ceramic wastewater treatment plant)
Our company develops a new generation of integrated ceramic sewage treatment equipment aiming at the problem of difficult sewage treatment in some ceramic factories. It combines flocculation, clarification and filtration processes into a compact and reasonable one, which can easily purify the raw water of general ground water source into living water meeting the sanitary standards. It is mainly suitable for ceramic factories, industrial sewage treatment, use, and also used for some The purification of near neutral production wastewater with the main purpose of removing suspended solids and colloidal impurities in the water.
九。植物油废水处理装置(Vegetable oil wastewater treatment unit)
植物油废水主要来源于设备冲洗水、新鲜骨冲洗水、地面冲洗水、生活污水、冷凝水等，原水水质为：cod为5000mg/L，BOD5为1500mg/L，SS、NH3-N、动植物油分别为1000、280、1200 mg/L。根据环保部门的要求(地区要求差异不大)，处理后的出水水质达到《污水综合排放标准》(GB 8978-1996)一级排放标准，即cod为100 mg/L，BOD5为20 mg/L，SS、NH3-N，动植物油质量浓度分别为70、15、10mg/L。
Vegetable oil wastewater mainly comes from equipment washing water, fresh bone washing water, ground washing water, domestic sewage, condensate water, etc. The quality of the original wastewater is as follows: cod is 5000 mg / L, BOD5 is 1500 mg / L, SS, NH3-N, animal and vegetable oil are 1000, 280 and 1200 mg / L respectively. According to the requirements of the environmental protection department (small differences in regional requirements), the quality of the treated effluent shall meet the first level discharge standard of the integrated wastewater discharge standard (GB 8978-1996), i.e. cod is 100 mg / L, BOD5 is 20 mg / L, SS, NH3-N, animal and vegetable oil quality concentrations are 70, 15 and 10 mg / L respectively.
十。酒厂废水处理厂(Distillery wastewater treatment plant)
The wastewater from liquor brewing mainly includes bottom water of retort, fermentation wastewater (also known as yellow water), washing water, water for cleaning site and water for packaging and bottle washing, etc. The main pollutants of sewage are sugar, alcohol, vitamin, etc., which are typical high concentration organic wastewater with high BOD value and good biodegradability. The concentration of organic matter in the bottom boiler water and mash waste water produced in the distillery is high, and the biochemical property is good, so the treatment is difficult. In order to ensure that the treated wastewater can meet the discharge standard, the combination of anaerobic and aerobic process is adopted. After the treatment, the concentration of COD, BOD5, SS, ammonia nitrogen, TP, TN and other indicators in the wastewater can reach the first level discharge standard of GB8978-1996.
十一。冶炼废水处理厂(Smelting Wastewater Treatment Plant)
