Test Study

t developed test devices and carried out test adopting combined process ofclarification-adsorption-membrane separationtargeted at surface water which was polluted by chemical agent VX. Investigation on purification effects of sand filtration, microfiltration, ultrafiltration, activated carbon adsorption and reverse osmosis was implemented in sections. It also researched on working principles of each section. Furthermore, comparative study has been made for adsorption performance of coaly granular activated carbon and that of shell activated carbon. The results show that the combined process can remove effectively simulation agent in water and the outlet quality complies with requirements of relevant standards.

The adsorption experiment was carried out in an enclosed reactor in order to evaluate activated carbon, prepared by brewing yeast, which could remove benzene, toluene, ethylbenzene, and xylene (BTEX) from air. Various experimental parameters were determined, and activated carbon adsorption performance was compared with some commercial activated carbons (CACs). The results showed that lots of carboxyl, amino-groups and hydroxyl were on the surface of activated carbon, which were chemical reaction centers. Adsorption was reached equilibrium after six hours. The isothermal data of biosorption followed the Langmuir and Freundlich Models. When the temperature was 25°C,the maximum adsorption capacity was greater than the commercial activated carbon. These adsorption performances indicate that the activated carbon is a potentially economical adsorbent for BTEX removal.

A case study is presented, in which two approaches to the treatment of complex chemical wastewater are experimentally compared: an end-of-pipe “best available technology” option and an in-plant source segregation program. Both options proved to be feasible. Application of the powdered activated carbon treatment (PACT™) process for the combined end-of-pipe stream yielded up to 93% reduction of dissolved organic carbon, with complete toxicity elimination. In order to examine the potential for applying a conventional activated sludge process, a simplified laboratory screening procedure was devised, aimed at establishing baseline data of removability potential, defined either by biodegradation, activated carbon adsorption or volatilization. Using this procedure, the major source of the non-biodegradable fraction in the combined park's wastewater was traced to a single factory, from which twelve individual source streams were screened. The results allowed the division of the tested sources into three groups: degradable, volatile, and problematic. A modified wastewater segregation and treatment program was accordingly proposed, which should allow an efficient and environmentally acceptable solution. This program is presently at its final testing stages, at the conclusion of which a full comparison between the two approaches will be carried out.
