Research on the Treatment Technology of Refractory Organic Compounds in Coal Chemical Wastewater

Abstract

With the proposal of the “Two Mountains Theory”, energy conservation and emission reduction have become the core
goal of the transformation of the coal chemical industry. How to treat the diffi cult to degrade organic matter in coal chemical wastewater
has become the primary problem that coal enterprises need to solve. Coal enterprises should clarify the characteristics of coal chemical
wastewater, adopt traditional treatment technologies, and use biochemical, physicochemical, and adsorption methods to remove diffi cult
to degrade substances from wastewater; Actively introducing oxidation technology, using ultrasonic oxidation technology, electrocatalytic
oxidation technology, etc. to treat difficult to degrade organic compounds in coal chemical wastewater; Reasonably utilizing biological
treatment technology to reduce environmental damage during wastewater treatment; Using membrane treatment technology to accelerate
the treatment of diffi cult to degrade organic compounds in coal chemical wastewater, enabling it to meet discharge standards and further
promoting water resource recycling.
