Abatement Strategy

Sludge agriculture application in future will be one of the main sewage sludge disposal ways in China. To ensure safety and environment of sewage sludge agriculture application, except to strengthen the research of sludge heavy metal, pathogen outside the organic contaminants will be one of the focuses of the future research, especially to strengthen the PAHs and NP/NPE. In order to reduce the environmental risks of sludge agriculture application, using biological aerobic fermentation processing technology treatment sludge can effectively reduce the organic contaminants, depress secondary pollution problem, which sewage sludge brings.

High Electric Field Strength

Abstract A resonant coupling mechanism is presented which leads to nearly full absorption of an electromagnetic wave in an overdense plasma column. In the resonance case a strong enhancement of the electric field strength within the plasma is found. Under certain conditions this high electric field strength causes parametric excitation of plasma waves in the underdense edges of the discharge. It turned out that the occurance of this decay process is mainly determined by the density gradients in the plasma.
