Ozone catalytic oxidation reactor

Ozone catalytic oxidation reactor

As a new technology in the advanced sewage treatment process, the ozone catalytic oxidation process has attracted widespread attention due to its advantages such as strong oxidizing property, fast reaction speed, low investment, good treatment effect, low operating cost, and no secondary pollution. This process can effectively remove inorganic substances in water, such as chromaticity, odor, iron, and manganese, and significantly reduce pollutant indicators of sewage like COD (Chemical Oxygen Demand), TOC (Total Organic Carbon), and ultraviolet absorption value. It is mainly used for the treatment of secondary effluent, municipal sewage, coking wastewater, printing and dyeing wastewater, landfill leachate, pharmaceutical wastewater, chemical wastewater, etc.

Electroplating wastewater

Electroplating wastewater

The waste gas in electroplating plants mainly comes from acid mist and alkaline gases volatilized during acid-base soaking. This waste gas is highly corrosive and poses significant hazards to the human body. Electroplating plants typically emit gases such as nitric acid, sulfuric acid, and hydrofluoric acid, which are treated using an acid washing tower. The process involves drawing the waste gas into the tower for neutralization treatment, followed by discharge through an exhaust fan to meet the emission standards.

Electrodialysis equipment

Electrodialysis equipment

Compared with reverse osmosis, another membrane separation technology introduced in recent years, electrodialysis is cheaper but has a lower desalination rate. In addition, the quality of domestic ion exchange membranes used before electrodialysis is also very stable, and their operation and management are quite convenient.

Multi-effect evaporator

Multi-effect evaporator

In large-scale industrial production, large quantities of water often need to be evaporated, requiring significant energy consumption to heat the water and generate steam. To reduce steam consumption, multi-effect evaporation can be employed. Heating steam is introduced into one evaporator, where the solution boils. In multi-effect evaporation, secondary steam can be used as heating steam and introduced into another evaporator. As long as the pressure in the latter evaporator and the boiling point of the solution are lower than in the original evaporator, the introduced secondary steam can function as a heat source. Based on the flow direction of the secondary steam and the solution, multi-effect evaporation processes can be classified as: co-current flow, counter-current flow, and cross-flow flow.

Electrodialysis semipermeable membrane

Electrodialysis semipermeable membrane

During the electrodialysis process, unlike ion exchange resins that undergo exchange reactions with certain ions in the aqueous solution, ion exchange membranes only exert a selective permeation effect on ions with different electrical properties. That is to say, ion exchange membranes do not require regeneration. The compartments composed of electrodes and membranes in the electrodialysis process are called electrode compartments, and the electrochemical reactions occurring therein are the same as ordinary electrode reactions. An oxidation reaction takes place in the anode compartment, making the anode water acidic, and the anode itself is prone to corrosion. A reduction reaction occurs in the cathode compartment, making the cathode water alkaline, and scaling easily forms on the cathode.
