【正文】 排放量大、廢水中含有多種有毒有害物質(zhì)、廢水成分復雜以及水量變化大等特點而成為目前我們所面臨的主要問題。s BOD is high, it could pollute the environment if drained before treatment, so it request the grape wastewater which drained must be strictly treated to the two effluence standard in the country, which is as following: BOD ≤ 20 mg/L , COD ≤ 90 mg/L , SS ≤ 60 mg/L . This paper analyzed the generation processes of wastewater, the major contaminats and their major sources in grape production. It also introduced the primary biological processing techniques of aerobic and anaerobic treatment. According to the product scale of grape brewery, the main standard of draining water\natural materials, and so on, the main process technology of the grape waste water disposal station is defined as UASB + CASS .Practice of project indicate, when COD of wastewater reduces from3000mg/l to 50~100mg/l, BOD reduces from 1600mg/l to 20mg/l, SS reduces from 1200mg/l to 60mg/l, so that drains out can reaches the Standard. The technological process of this design is: Grape waste water → Screens → The sewage lift pump house → Regulates tank → Reaction tank of UASB → Tank of CASS → Treatment water Abstrate III This technology of wastewater treatment has many traits. Such as, wellknit structure, pithy quick control, lasting attacked, less sledge capacity. Practice indicates that the posed craft has reliable function, its investment is little, and its running and management is unplicated.
