Sugar refining wastewater is a typical high-concentration organic wastewater, characterized by large production volume, high COD (Chemical Oxygen Demand) and BOD5 (Biochemical Oxygen Demand) concentrations, good biodegradability, and deep color. Its treatment process typically employs a multi-stage combination to achieve efficient and stable purification. The mainstream process flow can be
The choice of process generally depends on the hospital’s size, nature, and wastewater discharge destination. There are four main types of processes: primary treatment with enhanced treatment effects, secondary treatment, simplified biological treatment, and advanced treatment. Hospital wastewater treatment typically involves engineering design, construction, and acceptance procedures. Treatment facilities require
1. Screen Filtration 1.1 Principle: Using a screen to block larger suspended and floating solids in wastewater, allowing only smaller particles and water to pass through. 1.2 Application: Domestic and industrial wastewater treatment 1.3 Process Flow: Pre-treatment stage 1.4 Function: Intercepts large particles of various sizes 2. Sand Filtration 2.1
