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.

Pot experiments were conducted to study the roles of EDTA in phytoremediation of heavy metal-organic contaminated dredged sewage river sediment by Lolium multiflorum L.

Pot experiment was conducted to study phytoremediation of Lolium multiflorum Lam to heavy metal-organic contaminated dredged sewage river sediment.

The experiment soils were prepared by mixing dredged sewage river sediments with clean soil in different ratios.

The primary researches on the amount distributions and groups of purple non-sulfur bacteria in estuary sludge of Xinyang Shihe river were carried out.

The main contents related to the scheme were introduced as follows: the characteristics and status of sediment pollution,the determinati.

Water and sediment pollution at river mouths of Haihe River basin;

Progresses in remediation technologies for persistent toxic substances polluted sediments;

By taking polluted sediment dredging and disposal project of Caohai of Lake Dianchi as an example,assessment factors and focus are identified and analyzed.
