The discovered history, physical and chemical properties, toxic mechanism, curing method of vesicant agent were introduced; and the innocuously transformation of vesicant agent including the transfer of mustard gas and Luis gas into important material for solar battery and the use of toxic mechanism of vesicant agent for studying medicine of curing cancer were .

Study on harmless disposal and resource utilization of metallurgical wastewater;

Experimental Research on Harmless Technology of Municipal Solid Waste Incineration with Direct Gasification and Ash Melting;

Separate Collecting, Moving and Processing——A inevitable way accomplished city-garbage disposal harmlessness, resource and reduction;

Practice and Developing Trend of Harmless Sludge Treatments at Foreign Refineries Industry;

The pollution problem of noxious and harmful substance contenting in the fly ash such as heave metals, the dioxin becomes worse and worse, people has attach importance to the harmlessness of the fly ash yet.

Under the background of marketability, the paper explicates the problems of harmlessness and resources as well as handling countermeasures for urban domestic refuse in marketable process.

According to the principle of 'cleaner production' and the large amount of excess sludge production in the small-medium city,it is proposed that the trend of excess sludge disposal should be the disposal sludge and the sequence should be reduction,recycle and harmlessness of the sludge.

From the characteristics and its harmfulness of electroplating sludge containing heavy metals,the state of innoxious disposal and recycle of electroplating sludge at home and abroad are reviewed in this paper.

A new technology is developed, described as incineration-leaching- innoxious disposal.

According to idea of reduction,resource and hazard-free,entire-process management of domestic waste was discussed.

According to analysis the meaning of"reduction,resource and hazard-free"principle in domestic waste treatment,taking the situation in Shanghai as an example,an evaluating index system covering microcosmic"reduction,resource and hazard-free"evaluation and regional macroscopical"reduction,resource and hazard-free"evaluation was designed.
