Abstract
Small-scale sour starch agroinstry in Colombia suffer from absence of water treatment. Although starch processing plants proce diluted wastewater, it is a source of pollution and cause environmental problems to the nearby rural population. A laboratory scale anaerobic horizontal flow filter packed with bamboo pieces was evaluated for the treatment of cassava starch extraction wastewater. The wastewater used in the experimentation was the draining water of the starch sedimentation basin. The reactor was operated for 6 months. It was inoculated with a semi-granular sludge from an anaerobic UASB reactor of a slaughterhouse. Maximum organic loading rate (OLR) applied was 11.8 g COD/L d without dilution of the wastewater. At steady state and maximum OLR applied, 87% of the COD was removed and a gas proctivity of 3.7 L/L d was achieved. The average biogas yield was 0.36 L/g COD removed. Methane content in the biogas was in the range of 69–81%. The total suspended solids (TSS) removed were 67%. The relative high lactic acid content did not negatively influence the performance of the reactor. No perturbation e to cyanide (3–5 mg/L) was observed ring the reactor operation. The results obtained indicated that the anaerobic horizontal flow filter could be used efficiently for the treatment of wastewater from Colombian starch processing small-scale agroinstry.

Ⅱ 木薯酒精废水处理
1、木薯酒精废水处理达到不用排放剩余污泥的效果, 对实际工程应用具有内一定程度的指导意义。容
2、木薯酒精废水的pH低至4.0左右,然而其COD又高达10000 mg/L～70000 mg/L。经研究发现其可生化性良好,故采用UASB-SBR相结合的工艺处理。
3、厌氧反应器的反应温度通过水浴控制在37℃-38℃,水力停留时间为2 d,每个反应周期处理的水量为7L。好氧处理在常温下进行,溶氧控制在2 mg/L～4 mg/L。好氧产生的剩余污泥回流至调节池预处理原样废水。
4、同将剩余污泥回流至厌氧反应器内,将剩余污泥减量化处理,同时产生沼气,资源化利用。 在本课题研究过程中,通过采用UASB工艺厌氧处理,其厌氧阶段COD去除率达到90%左右,出水pH维持在7.0-7.3,厌氧反应体系的 VFA/ALK值0.1～0.3,在课题研究的最后,观察厌氧污泥,发现有颗粒状。
Ⅲ 小麦酒精的污水处理，相比玉米和木薯原料，是不是更加难处理啊
处理方式都一样，只不过不同原料制酒精所排放的废水污染物含量有所区别。一般现在很多酒精厂产用厌氧接触法的工艺处理酒精废水。
