With the rapid development of industry, industrial parks have become an important part of the city's economy. However, while industrial parks bring economic benefits, they also bring serious environmental problems, the most prominent of which is the problem of sewage treatment. To solve this problem, industrial parks need to install sewage treatment equipment. This article will introduce the types, characteristics and selection principles of sewage treatment equipment in industrial parks.
1. Types of sewage treatment equipment in industrial parks.
The sewage treatment equipment in the industrial park mainly includes the following types:
1.Activated sludge method.
The activated sludge method is a commonly used sewage treatment method, which mainly uses aerobic microorganisms in activated sludge to remove organic matter in water. This method has the characteristics of good treatment effect, simple equipment and convenient operation, and is suitable for sewage treatment of various scales.
2.Biofilm method.
The biofilm method is a method of removing organic matter from water using microorganisms attached to a biofilm. This method has the characteristics of strong impact load resistance, good treatment effect and low energy consumption, and is suitable for medium and large sewage treatment plants.
3.Natural biological treatments.
Natural biological treatment is a method of removing organic matter from water using microorganisms in the natural environment. This method has the characteristics of low investment, low operating cost and convenient maintenance, and is suitable for small sewage treatment plants.
2. Characteristics of sewage treatment equipment in industrial parks.
Industrial parks of different types and sizes need to choose different types and scales of sewage treatment equipment. The following are the characteristics of some common industrial park sewage treatment equipment:
1.High efficiency: The sewage treatment equipment in the industrial park should be highly efficient, able to quickly remove organic matter, ammonia nitrogen, total phosphorus and other pollutants in the water, and meet the national discharge standards.
2.Reliability: The sewage treatment equipment in the industrial park should be reliable, which can ensure the stable operation of the equipment, reduce the failure rate and improve the treatment efficiency.
3.Energy saving: The sewage treatment equipment in the industrial park should be energy-saving, which can reduce energy consumption and operating costs, and reduce the impact on the environment.
4.Environmental protection: The sewage treatment equipment in the industrial park should be environmentally friendly, which can reduce pollution and damage to the environment and promote sustainable development.
5.Maintainability: The sewage treatment equipment in the industrial park should be maintainable, which can be easily and quickly repaired and maintained, and the service life of the equipment should be prolonged.
3. Principles for the selection of sewage treatment equipment in industrial parks.
When selecting sewage treatment equipment in industrial parks, the following principles should be followed:
1.According to the water quality, water quantity, discharge standards and other factors of sewage, select the appropriate equipment model and process.
2.On the premise of satisfying the treatment effect, the equipment with low energy consumption and low cost is preferred.
