Rich students (Figure), Guangdong dyeing wastewater treatment company, provides printing and dyeing wastewater by the Guangzhou Environmental Protection Engineering Co., Ltd. Fu students. Guangzhou Fu students Environmental Engineering Co., Ltd. (www.fsyhb.com) is a leader in Guangzhou, environmental monitoring equipment, over the years, the company is implementing scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Rich students in leadership with the staff warmly welcome all inquiries negotiations to create a better future for rich students. Guangzhou Fu students Environmental Engineering Co., Ltd. is a set of environmental technology consulting, design, construction, equipment manufacturing and installation, commissioning, operation and technical output of hosting services as one of professional environmental company. The company is located in the historic, manufacturing developed Guangdong Guangzhou. Here and abundant human resources, marketing collaboration smooth and convenient transportation. Science and technology are primary productive force. The company has been committed to the market research and new product development, product updates, scientific and technological content increased, the product of the progressive realization of a single change to a wide range of printing and dyeing wastewater Pharmacy, excellent product quality and perfect after-sales service, praised by users . After years of effort, has a rich set of mature students environmental treatment processes in sewage, industrial waste water (dyeing, electroplating, paper, board, food, pharmaceutical, metallurgy, etc.), medical waste water, waste gas, solid waste, noise control areas ensure stable governance emission standards; in the water (drinking water, tap water, mineral water, industrial water, medical water, water reuse, etc.) in the field with advanced processing technology and rich experience. Xingtan dyeing centralized wastewater treatment works (3600m3 / d) is a rich source of students on behalf of the company Dyeing Wastewater Treatment Works. Rich students Xingtan dyeing wastewater treatment project focused on cotton textile products in the mix because of chemical fibers (mainly polyester) increases (generally 65%), which uses starch and polyethylene drunk warp yarn sizing when mixed slurry. In desizing wastewater pretreatment and dyeing process produces, since a certain amount of polyethylene drunk dyeing wastewater reuse, wastewater added biodegradable material, reducing the wastewater biodegradability. Therefore cotton dyeing wastewater is one of industrial wastewater difficult biodegradable. In wool dyeing products, natural fiber mountain in the proportion of people than the proportion accounted for a relatively small chemical fiber dyeing wastewater treatment, but also the weaving process without sizing, so the wool dyeing wastewater quality product produced by the process is relatively more stable, biodegradable waste is better than cotton products printing and dyeing wastewater discharge. Because scouring wastewater biodegradable performance, usually after extracting lanolin biological treatment method should be adopted. Silk printing and dyeing wastewater emitted during product processing belong to the low concentrations of organic wastewater, biodegradable good.
