Using microwave-ferrous sulfate modified activated carbon adsorption manner to remove the high concentration of phosphorus in wastewater. The power of microwavethe concentration of ferrous sulfate and reaction time on phosphorus removal were studied. When the power of microwave was 425W,the concentration of ferrous sulfate was 0.1mol/L,reaction time was 50 min,the removal rate of TP reaches 95.67%,the treated effluent TP can be dropped to 0.48mg/L,the TP can reaches the first effluent standard of TP in the comprehensive wastewater discharge standard (GB8978-1996).Microwave-ferrous sulfate modified activated carbon is adapted to treat high concentration phosphorus in the wastewater.

Available Technology

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.

The relationship between formaldehyde emission and time was researched and a mathematical model was developed which describes the variation of formaldehyde with time in the airtight chamber. It was found that high quality composite floor was in line with 0-order kinetic equation and low quality composite floor was in line with 1-order kinetic equation. Besides, the effect of activated carbon adsorption on formaldehyde was studied and the result showed that activated carbon had poor adsorption on formaldehyde for weak van der waals force.
