Municipal wastewater:

Municipal wastewater is primarily derived from domestic sewage, which typically consists of wastewater generated from daily household activities. This includes domestic waste and human excreta, as well as wastewater from kitchen cleaning, bathing, laundry, and toilet flushing. Its main characteristics are a large volume of water and a high concentration of suspended solids. These suspended solids frequently contain pathogens, organic matter, and plant nutrients such as nitrogen and phosphorus.

Typical Solution: Modified A/O (Anaerobic/Oxic) Process. 

The advantages of this process in treating municipal wastewater are evident:Its effective distribution design reduces the need for mechanical mixer energy, resulting in optimal interaction between wastewater and sludge.It provides efficient nitrification and denitrification, achieving excellent nitrogen removal.The process combines the benefits of both plug-flow and completely mixed reactor tanks.For residential community wastewater, integrated treatment units are available. These units offer the advantages of short construction periods, rapid startup, convenient operation and management, and simple maintenance. They can be installed indoors or outdoors, or even buried underground to integrate with community landscaping.
