The wastewater from explosive production was pretreated by iron-carbon micro-electrolysis process,and the effluent was treated by alkaline coagulation/aeration.

The adding-alkali aeration method is effective.

Both aerated coagulation and mechanical coagulation were tested and compared in the lab of a sewage treatment company.

The article introduces technology of add-alkali concrete sedimentating method treating phosphrus waste water.

Research on Aerated Concrete and Its Problems in Application;

Development of special mortar for plastering aerated concrete;

Use of aerated concrete and production technology;

Relation between strength and moisture content of aerocrete;

The application of new type wall materials in the modern buildings has promoted the rapid development of the building industry, and adopting some matched materials and suitable applied techniques possesses important significance for improving the quality of the buildings and for the popularizing the aerocrete, the new type wall material.
