It was studied that the performance of the internal electrolysis-Fenton process in pre-treating of the high-strength refractory acid dye wastewater. The sequencing comparative experiments were carried out and it was determined that the internal electrolysis-Fenton process was superior to the traditional one in terms of treatment effect. Optimal conditions were attained by experimental conditions changing...
Problems of seasonal ammonia nitrogen (NH3-N) and organic micro-pollution in drinking-water source have recently become common in cities of China, thus biological pretreatment process is helpful. The water flow of high-rate up-flow biological aerated filter (HUBAF) demonstration project was 735 thousand ton per day, there were 20 filters, sharing a common aeration system and an air-water combined...
Internal electrolysis of iron and carbon process was used to treat the wastewater produced in a medicine material plant. The principle of its pre-processing, process and the main technical process parameters were introduced in this paper. The results of this pilot scale test showed that the BOD5 /CODcr was significantly increased, and the wastewater could meet the third national emission standards...
The experiment used the iron carbon micro-electorlysis combined with sequencing batch biofilm reactor(iron carbon micro-electorlysis-SBBR) process to treat acrylic fiber wastewater. The iron carbon micro-eletrolysis-SBBR process could make the COD of acylic fiber wastewater from 550~700mg/L down to 140~165mg/L or so, and the removal rate of DMAC and acrylonitrile could respectively reach to 97.8%...
Membrane-making wastewater contains DMF, with high COD, toxicity and non-biodegradability. In this work, aerobic Fe-C micro-electrolysis and three-dimensional electrodes technology were applied for the pretreatment aiming to improve the biodegradability of the wastewater. It was found that the optional pretreatment conditions were pH 3 for Fe-C micro-electrolysis and pH 5 for the three-dimensional...
