厌氧折流板反应器处理化纤厂棉浆粕综合废水的实验研究

Study on cotton pulp comprehensive wastewater from fiber factory treatment with anaerobic baffled reactor

对新型厌氧反应器(ABR)处理化纤厂棉浆粕综合废水进行了研究。试验结果表明:采用ABR厌氧处理该废水,可以有效去除其中的有机物,在HRT为1d、进水COD为3360mg/L、有机负荷(OLR)为3.36kgCOD/(m3·d)的条件下,COD去除率为71.5%,出水COD降至958mg/L;利用浆粕黑液和纺丝废水混合调节pH,可以减少碱的用量,降低运行成本。

A study on pulp comprehensive wastewater from fiber factory treatment with a novel anaerobic reactor (ABR) was conducted. The result showed that the organic compound was biodegraded efficiently. At the conditions that HRT was 1 d, OLR is 3.36 kg COD/(m3·d) and the influent COD strength was 3 360 mg/L, the COD removal efficiency was 71.5% and the effluent COD strength was 958 mg/L. The pH value was regulated through mixing the cotton pulp wastewater and the filature wastewater, and so the amount of alkaline used and the cost of operation was decreased.
