To ensure the development of the poultry production,some management and technique must be put into practice to reduce the environment pollution,for example,to reinforce the harmless disposal of poultry offal;to develop the pollution-free animal feeds;to insist on the farming and animal husbandry model;to standardize management of the poultry production.

Based on management of harmless disposal to medical waste, a medical waste management information system was developed for Changchun City by analysis of data flow of medical waste management and system design.

Based on the waste residue's pollution mode and antipollution mechanism and some experiments, the paper provide approaches on harmless disposal and comprehensive utilization of it.

Study on the harmless treatment to leaking acrylonitrile;

Application of penicillinase in harmless treatment of penicillin slag

Advances in harmless treatment technologies of heavy metal wastewater

The study progress in innocuous treatment of phenolic wastewater;

This article has proposed the craft and effect of innocuous treatment about waste material,waste water and waste steam in the chemical production,waste water and waste steam in the chemical production by means of burning methods.

As a part of innocuous treatment study of waste drilling fluid, chemical destabilization of MMH drilling fluid was reported and the selectivity of synergetic destabilization effect between inorganic salts and polyacrylamides on the fluid was also discussed.
