Industrial wastewater treatment project refers to wastewater, sewage and industrial waste water generated in the process, which contains contaminants with water loss of industrial materials, intermediates and products, and the production process. Industrial Wastewater Treatment Project History With the rapid development of industry, industrial wastewater treatment processes, type and quantity of waste water of the rapid increase in water pollution are becoming increasingly widespread and serious threat to human health and safety. For the protection of the environment, the industrial wastewater treatment is more important than the urban sewage treatment. Although industrial wastewater treatment has already begun in the 19th century, and in the subsequent half century a lot of experimental research and production practice, but because of many complex components of industrial waste water, changing the nature of industrial waste water treatment factory, there are still a number of technical issues not fully resolved. This technology has matured and urban sewage treatment is different. Classification of industrial waste water treatment works usually have the following three: The first one is based on the main pollutants in industrial wastewater containing chemical nature of classification, containing mainly inorganic pollutants are inorganic waste water, containing mainly organic pollutants Wastewater. Such as wastewater electroplating wastewater and mineral processing, is the inorganic waste water; food or waste oil processing process, is organic waste. The second is based on the industrial company's products and the processing object classification, such as metallurgy wastewater, wastewater, waste gas coking coal, metal pickling waste water, waste water of chemical fertilizers, textile waste, dye wastewater, wastewater, pesticide wastewater, power plant waste Wait. The third is based on the main ingredient contained in the wastewater pollutants classified as acidic waste water, alkaline water, wastewater containing cyanide, chromium-containing waste water, waste water containing cadmium, mercury-containing waste water, wastewater, wastewater containing formaldehyde, oily wastewater , sulfur-containing waste water, waste water and radioactive phosphorus-containing wastewater. The first two classifications does not involve the main component contained in the wastewater pollutants, can not show the dangers of wastewater. The third classification, clearly pointed out the major pollutants in wastewater components, can show certain hazardous waste. Guangzhou Fu students environmental Xingtan dyeing centralized wastewater treatment works (3600m3 / d): wastewater treatment project in addition to heavy metals principles: waste water treatment works in addition to heavy metals Principle One: The most fundamental reform of the production process. No or less toxic heavy metals; waste water treatment works in addition to heavy metals Principle II: is the use of reasonable process, scientific management and operation, reducing the amount of heavy metals in waste water and with the loss of volume, to minimize the amount of wastewater discharged. Heavy metal wastewater treatment process should be in place in the production sites, mixing different other waste, so as not to complicate the process. It should not be used without further processing in addition to heavy metals directly into the city sewer, in order to avoid the expansion of heavy metal contamination. Wastewater treatment works in addition to the method of heavy metals, industrial wastewater emissions, can generally be divided into two categories: heavy metal waste water treatment works in addition to one: it is to heavy metals in waste water were dissolved state into insoluble metal compounds or elements, Zhongshan industrial waste by precipitation and floating removal from wastewater. The method can be applied as and precipitation, sulfide precipitation, flotation and removal, electrolysis precipitation (or floating) Act, by electrolytic wastewater treatment method; wastewater treatment works in addition to heavy metal Method two: heavy metals in the wastewater is not carried out under conditions of changing its chemical form of concentration and separation, the method can be applied to reverse osmosis, electrodialysis, evaporation and ion exchange method. These wastewater treatment alone or in combination should be used in accordance with wastewater quality, quantity and so on. Industrial waste water treatment works in industrial wastewater reuse treatment standard industrial water recycling rate is an important indicator of ecological urban construction, but also to measure the performance of local officials, "green index", has been incorporated into a mandatory standard in many industrial wastewater treatment economically developed regions. Guangzhou Fu students environmental Xingtan dyeing centralized wastewater treatment works (3600m3 / d): the discharge of industrial waste water, rich students (online consultation), Zhongshan industrial waste provided by the Environmental Protection Engineering Co., Ltd. Guangzhou Fu students. Environmental Protection Engineering Co., Ltd. Guangzhou Fu students (www.fushengyuan.com) is a leader in Guangzhou, environmental monitoring equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
