Wastewater treatment | Shanxi wastewater treatment equipment | Shanxi Runtong environmental (certified merchants) are provided by the Shanxi Run-Environmental Engineering Limited. Run-Environmental Engineering Co., Ltd. Shanxi (www.sxruntong.com) is specialized in the "sewage treatment, waste gas treatment, dust handling" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: generation manager. There are also the ease of hazardous waste treatment and waste water starting, the main pollutants in wastewater grouped into three categories: The first category is waste heat, mainly from the cooling water, cooling water can be reused; second category is the conventional pollution thereof, i.e., no obvious toxicity and easy biodegradable substances Shanxi wastewater treatment apparatus comprising a biodegradable organics, can be used as the compound of biological nutrients, and suspended solids and the like; third category is toxic pollutants of wastewater treatment, i.e., toxic and not readily biodegradable substances, including heavy metals, toxic compounds and is not easily biodegradable organic compounds. In fact, an industrial can be discharged in several different properties of wastewater, and a waste water and there will be different and different contaminant pollution effect. Such as a dye factory both acidic waste water discharge, and alkaline wastewater discharge. Textile printing and dyeing wastewater, due to the different fabrics and dyes, which are very different pollutants and pollution effects will be. Even a production plant effluents, may also contain several pollutants. Oil refinery overhead vapor such as distillation, cracking, coking, and other devices overlap condensation water, containing phenol, oil, sulfide. In different industrial companies, although the products, materials and processes different, it may discharge waste water of a similar nature. Such as oil refineries, chemical plants and coke gasworks, may have the oil, phenol wastewater discharge. Shanxi Run-Environmental Engineering Limited was founded in 2005, is a professional sewage treatment, waste gas treatment, dust handling and other environmental projects and research and design of high-tech enterprises. Paper industry wastewater treatment should focus on improving water recycling rate, reduce water consumption and wastewater emissions, but also should actively explore various reliable, economical processing methods and be able to make full use of wastewater useful resources. For example flotation recycled whitewater fibrous solids, recovery of up to 95 Shanxi mine wastewater treatment, water reuse clarification; combustion Blackwater recyclable sodium hydroxide, sodium sulfide, sodium sulfate and organic matter in conjunction with the other sodium salt. Adjusting the pH neutralization process wastewater; coagulation and sedimentation or flotation method can remove suspended solids in wastewater; chemical precipitation can decolorization; biological treatment can remove BOD, for more effective waste kraft paper; wet oxidation process sulfite pulp waste more success. In addition, there is also domestic and reverse osmosis, ultrafiltration, electrodialysis and other treatment methods.
