The principle of sewage treatment equipment is divided into the following three stages.
The first stage: We are familiar with physical treatment methods, usually letting the sewage pass through structures such as grilles, sand tanks, and primary sedimentation tanks to first remove coarse particles and suspended solids. The principle is that we physically separate solids and liquids firmly.
The second stage: It belongs to the microbial treatment method. Its principle is to use the physiological functions of the microorganisms themselves and through the decomposition and synthesis of microorganisms in the water to cause biochemical reactions between toxic and harmful substances in the sewage and microorganisms.
The third stage: The third stage is the chemical treatment method. It is a method of denitrification, dephosphorization, and ozone treatment using microorganisms. The sewage treated through this step can be used directly.
Introduction to sewage treatment equipment
Sewage treatment equipment is a kind of industrial equipment that can effectively treat domestic sewage, industrial wastewater, etc. in urban areas, preventing sewage and pollutants from flowing directly into the water area, which is harmful to It is of great significance to improve the ecological environment, enhance urban quality and promote economic development.
Underground sewage treatment equipment is suitable for domestic sewage in residential areas, hospitals and nursing homes, office buildings, shopping malls, hotels, restaurants, government agencies, schools, military units, aquatic product processing plants, livestock processing plants, dairy processing plants, etc. And similar industrial organic wastewater, such as organic wastewater treatment in textile, beer, papermaking, tanning, food, chemical and other industries.
The main purpose is to treat domestic sewage and similar industrial organic wastewater to meet the water quality requirements for reuse, so that the wastewater can be utilized as resources after treatment.
