摘要：

利用复合式厌氧折流板反应器(HABR), 以某生产全棉机织布的印染厂含硫酸盐印染废水作为原水, 在温度为30～40℃, 水力停留时间HRT=24 h条件下, 研究了m(COD)∶m(SO₄^2-)变化对HABR处理效能的影响。结果表明m(COD)∶m(SO₄^2-)>3时, 系统运行状况良好, COD、硫酸盐去除率均较高;当m(COD)∶m(SO₄^2-)≤3时, 系统运行效果较差。

Abstract:

The effect of the changes of m(COD)∶m(SO₄^2-) on the performance of the hybrid anaerobic baffled reactor(HABR) has been investigated, under the following conditions;hydraulic retention time(HRT) is 24 h, and temperature 30-40 ℃.The printing and dyeing wastewater containing sulfate from a cotton-woven cloth factory is used as raw water.The results show that when the influent m(COD)∶m(SO₄^2-) is 3, the operation situation of the system is pretty good;both of the removing rates of COD and SO₄^2-are pretty high.When m(COD)∶m(SO₄^2-) is ≤3, the operation effect of the system is rather poor.

Key words: hybrid anaerobic baffled reactor, printing and dyeing wastewater, volatile fatty acid
