What are the sewage efforts and support needed?
The main directions of wastewater treatment efforts include: improving the efficiency of sewage treatment. For different types, With the acceleration of urbanization, the development of the sewage treatment industry is becoming more and more rapid. This paper mainly analyzes the characteristics of different types and sewage in detail, and puts forward relevant suggestions and measures.
It is to improve the quality of domestic water: in modern society, "drinking water" is widely used in daily life, business and other fields; "Industrial wastewater" is composed of various substances, including chemical pollutants, which require effective measures to control their discharge and protect the ecological environment and human health.
It is a requirement for resource utilization. At present, the large amount of consumption and energy waste brought about by China's rapid economic growth has become one of the important problems restricting economic development, and China's sustained and rapid economic development has caused the people's living standards to continue to decline.
In particular, due to the huge population, barren land, and lack of technical strength in agricultural production in China's rural areas, the contradiction between supply and demand of water supply bodies has become increasingly prominent, making it difficult for some places to function normally, and even serious water shortages.
It also brings a lot of demand for renewable energy.
This will expose us to incalculable environmental problems.
Valuable lessons have been learned for the improvement of ecosystems.
It has also promoted the further development of the country's environmental protection undertakings.
(Sewage Run).The methods of sewage treatment are:
1. Physical method: mainly use the method of precipitation or air flotation to separate pollutants from water. Common ones include gravity separation and centrifugal separation.
2. Chemical method: It is a method of using coagulant to carry out redox reaction on organic substances. Commonly used are neutral agents ferrous sulfate, polyaluminum chloride, etc.; It is also believed that certain harmful substances can be removed using the ozone process.
3. Biological method: microorganisms need to consume a large amount of dissolved oxygen and metabolites in the process of sewage purification, so they need to absorb a large amount of organic nutrients in wastewater to degrade them into harmless substances. Commonly used are activated sludge method and biofilm method.
Dredging is one of the common tasks in urban management, in order to improve the efficiency of dredging and reduce the burden of labor, Barros has launched an efficient and intelligent dredging robot to help cities quickly clean up sludge and debris, and help cities to be cleaner and more livable, 4. Thermal power generation technology: increase the amount of wastewater by generating heat through high-temperature combustion, and reduce the calorific value in wastewater at the same time. It is often used to cool waste heat from industrial processes and convert it into useful water resources.
5. Environmental monitoring and treatment technology: including air quality detection system (CCTV), automatic water quality monitor and various types of data acquisition equipment. These instruments and equipment can monitor the sewage discharge, influencing factors and their changes in real time, and provide important facilities and services that provide scientific evidence to protect human health and promote economic development.
