If sugar refining wastewater is discharged directly without treatment, it will cause serious harm to the aquatic environment and ecosystem, mainly in the following aspects: 1. Depletion of dissolved oxygen in water, leading to black and smelly water bodies. Sugar refining wastewater contains high concentrations of carbohydrates, proteins, pectin, and
The selection of different wastewater pretreatment methods should be comprehensively considered based on the wastewater characteristics, treatment objectives, and subsequent process requirements. The following are common pretreatment methods suitable for the following scenarios: 1. Industrial wastewater contaminated with high concentrations of organic matter, suspended solids, and color (such as pharmaceutical
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
The composition of industrial wastewater varies significantly by industry, primarily encompassing the following categories: 1) Organic pollutants Common in industries such as petrochemicals, pharmaceuticals, and dyes, these pollutants include phenols, benzene series, polycyclic aromatic hydrocarbons, organic chlorides (such as carbon tetrachloride), and aldehydes (such as formaldehyde). Wastewater from industries such
In the zero-discharge treatment project of industrial wastewater, the main pumps involved are water inlet pumps, high-pressure pumps, booster pumps, circulation pumps, and chemical dosing pumps. These pumps are mainly centrifugal pumps/plunger pumps, screw pumps/slurry pumps, metering pumps, axial flow pumps, and sometimes shielded pumps. The uses of these pumps
