In this paper,we investigated the effect of pH value of cathode rinse liquid on electrokinetic(EK) remediation processes of sediment.

The effect of electro-kinetic treatment on the removal of main heavy metals in sediment under various voltage drops was investigated.

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

Situations of river sediment disposal of Shanghai and Pengyuepu River are introduced.

Main components and features of river sediment are introduced Secondary pollution of river sediments to the water quality of the river is clarified Studies on importance and approaches to reutilization of river sediment are elucidated and carried out, which lead to the future and problem of the reutilization of river sedimen

The principle, method and results of measuring specific surface area of ceramisite made of river sediment are discussed.

Study on the Heavy Metal Pollution in Sediment of Fen River;

Seeded with normal anaerobic granular sludge,mixed sludge(normal anaerobic granular sludge and aerobic activate sludge),river sediments respectively, feeding with synthetic wastewater containing ammonia and nitrite, three similar lab-scale UASB systems were started up.

s: Using river sediments as seed sludge, at the condition of pH 5.

Effects of some major factors of anaerobic fermentative biohydrogen production with organic substrates was evaluated using preheated river sediments as seed sludge The results showed that: at 35 ℃ and initial pH of 65, these sediments could use different sugars including xylose,glucose,fructose ,sucrose,cellobiose,starch as substrates to produce hydrogen.

A gas chromatographicmass spectrometric method (GCMS) for the simultaneous determination of environmental estrogens (including 4nonylphenol, bisphenol A, diethylstilbestrol and 17αethinylestradiol) and endogenous estrogens (including 17αestradiol, 17βestradiol, estriol and estrone) in urine and bed mud is reported.
