Dyeing and printing wastewater can only be treated through a combination of processes. While developing these processes, it’s also crucial to achieve recycling and reuse, striving for zero wastewater discharge. (1) Conditioning: For wastewater with significant variations in water quality and quantity, the conditioning tank should have a longer retention
It is necessary to select an appropriate combination of technologies based on the water quality characteristics. The following are common and efficient methods: 1. Chemical oxidation method 1.1 Fenton oxidation: Utilizes the reaction of Fe²⁺ with H₂O₂ to generate hydroxyl radicals (·OH), which can efficiently degrade refractory organic matter
1.Coking wastewater is a typical toxic and difficult to degrade organic wastewater.Sources of coking wastewater Coking wastewater mainly comes from multiple links in the coal coking production process, among which residual ammonia accounts for the largest proportion, followed by wastewater generated by processes such as coal gas purification and chemical
