With the acceleration of urbanization, the discharge of domestic sewage is increasing, which has caused a great burden on the environment. In order to solve this problem, domestic sewage treatment equipment came into being. This article will introduce the types, characteristics and applications of domestic sewage treatment equipment in order to better understand this field. Sewage treatment
1. Types of domestic sewage treatment equipment.
1.Activated sludge treatment equipment.
Activated sludge is a commonly used biological treatment technique that degrades organic matter by cultivating microorganisms. The equipment mainly includes aeration tank, sedimentation tank, sludge return system and other parts. Activated sludge treatment equipment has the advantages of good treatment effect and wide range of application, but it also has problems such as large investment and high energy consumption. 
2.Biofilm processing equipment.
The biofilm method is a treatment method that uses biofilm to filter wastewater. The equipment mainly includes biological filters, biological turntables and other parts. Biofilm treatment equipment has the advantages of good treatment effect, stable operation, energy saving and environmental protection, but it also has problems such as large floor area and high investment.
3.Anaerobic biological treatment equipment.
Anaerobic biological treatment is a method of degrading organic matter using anaerobic microorganisms. The equipment mainly includes anaerobic reactor, sedimentation tank and other parts. Anaerobic biological treatment equipment has the advantages of low energy consumption, high organic load, and low amount of residual sludge, but it also has problems such as unstable treatment effect and peculiar smell.
4.Composite biological treatment equipment.
Composite biological treatment is a comprehensive treatment method that combines activated sludge method, biofilm method and anaerobic biological treatment. The equipment has the advantages of good treatment effect, stable operation, energy saving and environmental protection, but at the same time, there are also problems such as complex equipment and difficult maintenance.
2. Characteristics of domestic sewage treatment equipment.
1.Good treatment effect: all kinds of domestic sewage treatment equipment can effectively remove major pollutants such as COD, BOD, SS, etc., and meet the national discharge standards.
2.High degree of automation: Modern domestic sewage treatment equipment usually adopts advanced automatic control systems, which can realize remote monitoring and control and reduce manual intervention.
3.Adaptability: Domestic sewage treatment equipment in different regions and under different water quality conditions can be customized and optimized according to the actual situation to meet specific needs.
4.Energy saving and environmental protection: The energy consumption of domestic sewage treatment equipment is low, and the amount of residual sludge produced is small, and the environmental impact is small.
