The Party Center put forward the development concept of harmony between humans and nature, and Chairman Xi Jinping even pointed out that green mountains and green waters are Jinshan Mountain. This is not only a strategic decision for the revival of Chinese people, but also the main approach to implementing national environmental protection policies. It is a must for the sustainable development of economic development. In the process of urban and industrialization construction, various offices and investment construction entities should especially stay in the influence of sewage on natural environments in the Italian industrial environment, strengthen the treatment methods, and cannot destroy human resources and preserve their homes due to a temporary advantage.
1. Definition and treatment methods of industrial sewage treatment
Industrial sewage treatment is to deeply treat wastewater generated during industrial production, which plays a major role in protecting the environment and reducing environmental burden.
Industrial wastewater (industrialwastewater) contains wastewater and wastewater, which refers to wastewater and wastewater produced during industrial production. EscortThe Sugar daddy contains industrial production materials that flow away from water, intermediate products, sub-products and purified substances produced during production.
Industrial wastewater is a dream. Ye was forced to witness the entire book. The content mainly refers to wastewater, sewage and wastewater produced during the industrial production process, which contains industrial production materials, intermediate products and products that flow away from water, and purified substances produced during the production process. With the agility of the industrySugar babyhilippines-sugar.net/”>Pinay escort has grown rapidly, and the purification of water has also become increasingly common and serious, threatening human health and safety. Therefore, for the protection of the environment, industrial wastewater treatment is more important than urban sewage treatment.
<a With the development of our country's industrial development, the emission of industrial wastewater is increasing, and Sugar daddy is a sure impact on the basin environment and the health of residents. Manila escortIn recent years, our country has been paying more and more attention to the management of industrial wastewater.

Depending on the differences in the depth of treatment, sewage treatment can be divided into first-level treatment, second-level treatment and deep treatment. First-level treatment is important for removal of water-soluble substances, and adjusting Sugar daddy pH value and lightening sewage wall drop level; second-level treatment is important to use activated sludge, biofilm method, chemical method, etc. to ablate organic matter into the sewage removal; third-level treatment is heavy and heavy. daddyTo apply the MBR method to develop the “Well, Aunt Wu, see you again.” A step to degrade substances, trace amounts of toxic organic matter, etc. into the sewage removal. According to the “Technical Policy for Urban Sewage Treatment and Purification Prevention and Control”, sewage treatment facilities with a daily treatment capacity of more than 200,000 cubic meters (including 200,000 cubic meters/day are commonly used to use the conventional activated sludge method. Other mature techniques can also be used.
2. Current status of industrial sewage treatment industry
Investment in domestic industrial wastewater management projects from 2009 to 2016<a The amount of funds in Sugar daddy exceeded 10 billion yuan, and the investment amount of projects in 2017 was more obvious to 76.38 billion yuan. The investment amount in 2016 was intended to peak in 1.0824 billion yuan. The investment scale of my country's industrial wastewater management project in recent years is shown in the following figure:
Industrial sewage has the characteristics of complex structure, large water quality and water volume, high concentration of purified substances, a wide variety of purified substances, toxic and difficult to degrade. Industrial sewage is divided into two types: clean wastewater and production sewage. Clean wastewater is mainly connected to cold water from industrial equipment. Any water temperature is high and light, and can be easily processed and then recycled or discharged into water. manila body; The production of wastewater is important from the wastewater generated by direct contact with the produced material during the production process. The purification level is more serious and must be strictly treated before it can be applied or discharged into the water.
