气浮-厌氧-好氧联合工艺处理1,4丁二醇、聚四氢呋喃废水

Air floatation-anaerobic-aerobic combined process for the treatment of 1,4-butanediol, polytetrahydrofuran wastewater

本文将废水分为高浓度甲醛废水、高浓度不含甲醛废水和低浓度废水。该工程经过一年多的稳定运行,出水完全可达到《污水综合排放标准》三级标准,同时工艺稳定、可靠、高效,可为同类化工废水处理提供借鉴作用。

This paper divides wastewater into high-concentration formaldehyde wastewater, high-concentration formaldehyde-free wastewater and lowconcentration wastewater. After more than one year of stable operation, the effluent can fully meet the “Sewage Comprehensive Emission Standard” level 3 standard, and the process is stable. Reliable, efficient, and provide reference for similar chemical wastewater.
