What are the Different Methods of Water Control?

Water pollution control is a method to control the discharge of pollutants into water bodies. Water pollution is mainly caused by pollution sources and surface pollution sources. Point pollution sources have specific pollution sources, such as the outlets of sewage pipes in factories. It is easier to treat as long as there is sufficient law enforcement to control pollutant discharge Capacity, each industry has specific pollutants, which can be controlled by developing pollutant emission control technologies. The main cause of industrial pollution is that enterprises are unwilling to increase costs by themselves, and pollution control must be enforced by the government and public opinion.

Water pollution control

The urban sewage treatment plant uses microorganisms to decompose and absorb organic matters in the water, and then oxygenates the water, which is called "aeration".

Activated sludge process

Organisms grow and reproduce rapidly, forming "active sludge", which is actually a mixture of certain algae, bacteria, and fungi that can decompose and absorb organic matter in water to purify the water. Sewage treatment plants have a variety of different technologies, such as the traditional technology of aeration head aeration, the oxidation ditch technology of rotary brush aeration, and the AB method of decomposing macromolecules with anaerobic bacteria and then aeration. However, urban sewage treatment plants cannot allow certain industrial wastewater containing toxic substances to enter to prevent activated sludge poisoning from purifying. Industrial wastewater needs to specifically design purification schemes based on the different pollutants it contains, or use specially cultivated bacteria. Species.

The state uses legal, economic, administrative, and technical means and measures to monitor and manage the discharge of pollutants that pollute water bodies in order to protect the quality of water bodies.

The Ministry of Agriculture of China has announced the maximum standards for the use of various pesticides, but because the standards are not compulsory, all farmers must be educated to understand and master them.

Only by implementing strict water pollution control can water resources be effectively protected and made sustainable. In addition, water pollution control can also promote the reform of production processes.
