The printing and dyeing wastewater purification powder not only has efficient purifying capability but also can remove a plurality of pollutants.

Description

technical field [0001] The invention relates to a printing and dyeing wastewater purification treatment powder and a preparation method thereof, belonging to the field of sewage purification. Background technique [0002] Water is an important natural resource for the survival and development of human society. With the rapid development of industry, water pollution is constantly escalating, and the wastewater produced by textile printing and dyeing is an important source of water pollution. At present, the treatment of printing and dyeing wastewater mainly includes physical methods, biological methods and chemical methods, among which chemical methods are widely used. my country's textile printing and dyeing industry is developing rapidly. The discharge of printing and dyeing wastewater is large, and the composition is complex and difficult to treat, including various organic, inorganic, hydrophilic and lipophilic toxic substances. However, the treatment efficiency of existi...

Problems solved by technology

my country's textile printing and dyeing industry is developing rapidly. The discharge of printing and dyeing wastewater is large, and the composition is complex and difficult to treat, including various organic, inorganic, hydrophilic and lipophilic toxic substances. However, the treatment efficiency of existing chemical treatment agents for printing and dyeing wastewater is still relatively low. Low, resulting in the discharge of printing and dyeing wastewater that cannot meet the standard after treatment
