Reduction of wastewater toxicity and change of microbial community in a hydrolysis acidification reactor pre-treating trimethylolpropane wastewater
Abstract
HAP was verified to reduce the toxicity of TMP wastewater effectively. Actual TMP wastewater was fed in HAP with different dilution ratios for 240 days. Formaldehyde, 2-ethylacrolein, TMP and 2-ethylhexanol were all greatly removed. Firmicutes became the dominant phylum (the abundance increased to 57.08%).
