The treatment of wastewater from glass factories mainly adopts a combined process of “pretreatment + main treatment + advanced treatment + reuse” to achieve compliant discharge or resource reuse, as detailed below: 1. Pretreatment 1.1 Bar screen/screen: Removes large particulate impurities 1.2 Equalization tank: Balances water quality and quantity 1.3
The wastewater treatment process for garment factories is designed based on the source and characteristics of their wastewater. Based on the actual production processes in the garment industry, the typical mainstream treatment process adopts a combination of “pretreatment + biological treatment + advanced treatment + disinfection/sludge treatment,” with the specific
Garment wastewater mainly originates from washing, dyeing, and finishing processes in garment manufacturing. Its water quality typically exhibits the following characteristics: 1. High organic matter concentration: Contains large amounts of fiber debris, sizing agents (such as PVA), dyes, and auxiliaries, resulting in high COD (Chemical Oxygen Demand) and BOD (Biochemical
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
There are many methods for treating aquaculture wastewater, which can generally be categorized into four main types: biological treatment, physical treatment, chemical treatment, and natural treatment. 1. Biological Treatment: This method uses the metabolic activity of microorganisms to transform organic pollutants in solution, colloid, and finely suspended states in wastewater
Commonly used aerobic biological treatment methods include activated sludge process, deep well aeration process, adsorption biodegradation process (AB process), contact oxidation process, sequencing batch reactor (SBR) process, and circulating activated sludge process (CASS process). (1) Biological Contact Oxidation Process: This technology combines the advantages of activated sludge and biofilm processes,
The core differences between drinking water treatment and wastewater treatment lie in their treatment targets, objectives, and process flows: 1. Differences in Treatment Targets Drinking water treatment targets natural water sources (such as surface water and groundwater), aiming to remove suspended solids, microorganisms, and harmful substances to ensure water quality
