10万吨糖蜜酒精生产线 高浓度有机废水处理项目100,000T molasses alcohol product line high concentrated organic wastewater treatment project 工 艺 技 术 方 案Process Technical Design 青岛国桥进出口有限公司（CBC）Qingdao ChinaBridge Imp. Exp. Co., Ltd（CBC） 二OO九 年 四 月第一章 简 介Chapter One Summary 我公司投资的10万吨糖蜜酒精，用甘蔗汁为原料产生废糖蜜经过发酵生产酒精，在生产酒精的过程中产生高浓度有机废水。酒精废水未经处理就近排入水体，会造成一定程度的污染，因此，必须建设配套的污水处理设施。The project of 100,000T molasses alcohol product line, use sugarcane juice as raw material to produce sugar cane juice, after fermentation, it produce alcohol. Meanwhile, high concentrated organic wastewater is brought out. If charge the waste water without treatment, it will result in pollution. Therefore, the matching waste water treatment is necessary to build. 工程规模为日处理酒精废水3372m3 /Project scale: deal with alcohol wastewater 3372 m3 per day. 污水处理采用厌氧—好氧处理工艺/ The wastewater treatment adopts anaerobic + aerobic process. 工程总投资为5821400美元/ The total investment is 5,821,400 U.S. dollars. 污水处理运行成本为0.225美元/m3。 The running cost for wastewater treatment is 0.225 U.S. dollars / m3. 第二章 工程规模与处理程度 Chapter Two Project scale and treatment level 第一节 规模的确定Section one Scale control 根据我公司对糖蜜酒精污水处理的治理经验，及厂方提供的数据，确定水量如下：According to the experience on molasses alcohol wastewater treatment and information provided by the factory, the determined water quality is as follows:  糖蜜酒精酒糟水为3372 m3/d（含水93.4%）Molasses alcohol distillers grains water 3372 m3 / d (moisture content 93.4%) 经板框过滤后水量为2300 m3/d。Water quantity after plate and frame filter press is 2300 m3 / d. 第二节 进水水质的确定Section two Quality control of inflow water 参照同类生产企业的酒精废水参数，及公司确定精废水处理工程的进水水质设计为： CODcr ≤80000mg/l（板框过滤前） CODcr ≤45000mg/l（板框过滤后） BOD5 ≤25000mg/l SS ≤5000mg/l NH3-N ≤180mg/l PH ： 4—4.5 T ≤ 80℃ Referring to the molasses alcohol parameters of the same type manufacture factories and the determined wastewater value, the design is as follows: CODcr ≤80000mg/l（before plate and
