Integrated judgment for the maturity degree of sludge compost using probabilistic neural network;

Effects of simulated acid rain on form transformation and environmental behaviors of heavy metals in amended sludge compost;

Application of Sewage Sludge Compost in Cultivation of Flower;

Effect of sewage sludge compost and its Dissolved Organic Matter (DOM) on desorption and leaching of Fluoranthene from soil;

Study on reducing toxicity to plant from sewage sludge compost treated by different passivation reagents;

Influence of sewage sludge compost on red sage growth;

Two kinds of aeration modes,five kinds of amendment were tested in sewage sludge composting.

The results showed that the ambient temperature had some effect on sewage sludge composting process.

Pilot scale test was carried out on the sludge composting by using 5 kinds of conditioner (wood chips,wheat hulls,rice hulls,corn cores,and recycled sludge compost) and monitoring was made on moisture content,organic matters total nitrogen,NH 3 N,NO 3 N, BOD 5 ,and specific oxygen uptake rate ( SOUR ).

The paper introduces the status,technical developing direction and the relevant standards of sludge composting industry in our country,compares the differences between construction,operation and sewage treatment of sludge composting project.
