Domestic Wastewater Treatment Equipment | Integrated Domestic Wastewater Treatment

Working Principle Domestic sewage first enters the unit, where a screen or equalization tank removes large debris. Then it flows into the biological treatment zone. Under anoxic and aerobic conditions, microorganisms break down organic matter while also removing ammonia nitrogen and total phosphorus. After that, the water moves into the settling zone for solid-liquid separation, and the clear water is disinfected before it's discharged. Integrated domestic sewage treatment puts pre-treatment, biological reaction, settling, and disinfection all in one unit. It's compact, takes up little space, and runs reliably — a good fit for communities, towns, schools, hospitals, and similar places. Application Fields 1.Residential communities: centralized treatment of household sewage, then discharge or reuse once it meets standards. 2.Towns and villages: decentralized sewage treatment to improve local water quality. 3.Schools and hospitals: treatment of campus and hospital sewage to reduce pollution risks. 4. Hotels: treatment of guest room and restaurant sewage to cut down on discharge loads. FAQ Q1: Where are domestic sewage treatment systems usually used? A: Mostly in residential communities, towns, schools, hospitals, and hotels. These places don't generate huge amounts of sewage each day, but the sources are scattered, and hooking up to the municipal sewer isn't always practical. So on-site treatment makes more sense. The unit can be buried underground, with landscaping on top, so it doesn't take up usable space. Q2: How does integrated domestic sewage treatment work? A: Sewage first enters the unit, where a screen or equalization tank removes large debris, then it flows into the biological zone. Under anoxic and aerobic conditions, microorganisms break down organic matter and also remove ammonia nitrogen and total phosphorus. After that, it goes into the settling zone for solid-liquid separation, and the clear water is disinfected before discharge. The whole process happens inside one unit — no need to build separate tanks. Q3: What are the advantages of an integrated unit over traditional sewage treatment setups? A: Traditional setups require separate equalization, biological, and settling tanks, which take up a lot of space and take longer to build. An integrated unit combines all of these into one system — compact, small footprint, quick to install. It also runs steadily and is easy to maintain, making it a good fit for sites with modest flow and limited space. The treated water can meet discharge standards or be reused for irrigation or toilet flushing.
