Progress of hydrogen sulfide waste gas treatment;

,Ltd in these five years:including waste gas treatment,waste liquid treatment and treatment of waste water.

Through a project example,this article introduces the catalytic combustion which can be applied in the waste gas treatment of VOCs with small air volume and high concentrations,and illustrate its characteristics,advantages and notes.

This article introduces briefly methods of utilizing carbide slag resource in industries such as cement,construction materials,mining and metallurgy,chemical production and wastes treatment and analyzes the feasibility and utilizing quantity for each method.

The advanced adiabatic nitration technology, liquid phase hydrogenation technology and wastes treatment technology are introduced.

Using Eastman waste water treatment case,this paper presents the detailed scheme to combine simulations with ex- periments for process design.

With the analysis of the water quality of the coal conveying system in the coal-fired power plant and in combined with the waste water treatment in Xibaipo Coal-fired Power Plant, a chemical flocculation was used to treat the waste water.

Monitoring and assessing the processes for waste water treatment employed in different factories, we screen out reasonable ones, achieving the Drainage Standard with lowered operational expense.
