125, The total chromium in the sludge wastewater can be determined with the microwave digestion - photometry method.

126, Accumulation of pirimicarb in sludge, grass carp, duckweed and water lettuce increased with time. In the meantime, concentration of pirimicarb in aquatic phase decreased continuously.

127, The experiment study the pyrolysis behaviors of coal slime and riverbed sludge using the method of liner warming.

128, This paper has put forward an activated sludge system model(ASSM)based on the simplified bio -reaction dynamics model(SBDM)and the secondary clarifier model.

129, By means of chemical agent, oily sludge treated and changed into active thickening profile control agent.

130, The sludge residence time in the screw press and thus the filtration time can be adjusted to individual requirements by adjusting the rotational speed of the screw shaft.

131, How to availably treat oil - bearing sludge always is a practical trouble puzzled in wastewater treatment field.

132, Whereas , Sludge disposal technologies include incineration, land filling, land application and building materials.

133, The acute biological toxicity of residual chlorine and five organic chlorides against normal backflow activated sludge in a CHLOR-ALKALI factory was examined.

134, EMHYDR HR oils have excellent oxidation stability and demulsibility, enabling ready separation of entrained water and giving long life without formation of harmful sludge.

135, The purpose of this study is to improve the concentration of nitrifying bacteria in the active sludge through improving substrate concentration.

137, Respirometer was used to monitor microbial activity in activated sludge.

138, The SCWO process, on the other hand, can convert virtually all of the heating value of the sludge to hot water or steam without the need for stack gas scrubbing.

139, It is an approved technology of microaerobic granular sludge to degrade pentachlorophenol (PCP) because aerobic oxidation and anaerobic reduction can simultaneously occur.

140, It is proved that the addition of TCP as a metabolic uncoupler into activated sludge can reduce the yield of excess sludge.
