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 木薯酒精廢水處理
1、木薯酒精廢水處理達到不用排放剩餘污泥的效果, 對實際工程應用具有內一定程度的指導意義。容
2、木薯酒精廢水的pH低至4.0左右,然而其COD又高達10000 mg/L～70000 mg/L。經研究發現其可生化性良好,故採用UASB-SBR相結合的工藝處理。
3、厭氧反應器的反應溫度通過水浴控制在37℃-38℃,水力停留時間為2 d,每個反應周期處理的水量為7L。好氧處理在常溫下進行,溶氧控制在2 mg/L～4 mg/L。好氧產生的剩餘污泥迴流至調節池預處理原樣廢水。
4、同將剩餘污泥迴流至厭氧反應器內,將剩餘污泥減量化處理,同時產生沼氣,資源化利用。 在本課題研究過程中,通過採用UASB工藝厭氧處理,其厭氧階段COD去除率達到90%左右,出水pH維持在7.0-7.3,厭氧反應體系的 VFA/ALK值0.1～0.3,在課題研究的最後,觀察厭氧污泥,發現有顆粒狀。
Ⅲ 小麥酒精的污水處理，相比玉米和木薯原料，是不是更加難處理啊
處理方式都一樣，只不過不同原料制酒精所排放的廢水污染物含量有所區別。一般現在很多酒精廠產用厭氧接觸法的工藝處理酒精廢水。
