设计总说明
制药废水的特点是成分复杂,有机物含量高、毒性大、色度深及含盐量高,可生化性较差,且间歇排放,属难处理的工业废水。制药废水一般难以降解,可长期存在于环境中。
本设计针对300吨/天制药废水,进水水质为:BOD5:130mg/L,CODCr:400mg/L,pH:6-9,SS:150mg/L。出水水质达到国家工业废水二级排放标准。针对该制药废水的特点,参照国内外经验,运用膜SBR工艺,废水经酸化调节池,初沉池,膜SBR池后,有效降低废水中的COD、BOD,使废水出水水质达到国家工业废水二级排放标准。相对于其他工艺,采用膜SBR工艺有节能,占地少,造价低,无须处理污泥,运行成本低等优点。本设计处理水量为300m³/d,为小型工程,工程地点设置在制药厂区内,方便处理,经处理后的出水直接运用于制药厂区绿化用水。经计算,工程总投资为105万元左右,。

Design Illuminate
Pharmacical wastewater is characterized by s, high concentrations anic matter,high toxicity , deep color and high salt contents ,poor biodegradability,and intermittent emissions,which make it industrial wastewater hard to deal with. It is also very difficult to degrade,and can exist in the environment for a long of anic pollutants exist in pharmaceutical wastewater are easy to cause water pollution,and have posed a huge threat to humen the development of Chinese pharmaceutical industry,pharmaceutical wastewater has gradually e one of the major sources of how to handle the pharmaceutical wastewater es a difficult problem in environment protection.
The design for the pharmaceutical wastewater by using membrane technology, SBR, can effectively reduce the wastewater COD, BOD, the effluent quality can meet the national wastewater discharge standard of two grade. Compared with other process, using the membrane SBR process has energy saving, less land occupation, low cost, no sludge treatment, has the advantages of low operating cost. The design treatment capacity is 300m University /d, for small projects, project location convenient setting processing in the pharmaceutical factory,, the treated effluent is directly used in pharmaceutical plant green water. By calculation, water treatment costs yuan per cubic.
