Experimental study in biochimical biofilter with lightweight ceramic cake to purify of waste gases containing organic compounds in low concentration;

Research on biofilm culturing of the light ceramsite for the ecological filter bed

After being preheated and fired,dewatered sludge with additives is made into light ceramsite that can be used as filler for sewage purification and for decoration,etc.

On the basis of introducing the study on using sewage sludge from sewage treatment plant as a source to produce a new kind of building material-light ceramsite both at home and abroad,the application prospect of the technology on aspect of preparation technologym,technical feasibility analysis and the economic and environmental profits are discussed.

Experiment acid etching at different temperatures and for different times were carried out on the light weight white pottery from Dehua.

Combined with practical work,in view of the different conditions of various parts of lightweight block various construction technology and material selection are introduced;at the same time corresponding measures are proposed to control outside-wall leakage to ensure appearance quality of building.
