【摘要】 棉浆粕废水组分较为复杂,治理具有一定的技术难度,采用两相厌氧、序批式活性污泥法和物化处理组合工艺取得了较好的效果。生产运行结果表明:SBR工艺对COD,BOD的去除效率分别达到40％～57％和55％～70％。在水温自然变化情况下,测定了好氧SBR单元的生化动力学参数,并与已有文献报道的纸浆和造纸废水的测定结果进行了比较,表明棉浆粕废水经两相厌氧处理后的出水更易于生化处理,但仍属较难好氧生化处理废水。更多还原

【Abstract】 Pulp wastewater is comparatively complicated, and there are some difficulties in the treatment. Favorable result has been got when using the two-stage anaerobic, sequencing batch reactor (SBR) and physico-chemical combined technology. It is indicated in practice that COD, BOD removal rate can be up to 40% -57% and 55% -70% in SBR respectively. Kinetic constants were determined under the naturally changed temperature of the wastewater. Compared with the experimental results reported in the literature about the paper pulp mill wastewater, it indicated that the effluent of the two-stage anaerobic system was more biodegradable than the raw paper pulp mill wastewater, but it still belonged to the hard-to-biodegradable wastewater.更多还原
