TL-1(A)型污水COD速测仪在萝北企业污水排放监测中的应用

Application of TL-1(A) Type Waste Water Quick Determining Instrument in Luobei Enterprise Exhaust Waste Water Monitor

萝北县环境监测站采用TL-1(A)型污水COD速测仪测定企业排放污水中的化学需氧量,此法在强酸性介质中,复合催化剂存在下,恒温消解水样只需10分钟,操作简单,工作效率高,克服了重铬酸钾法耗时长,每次只能同时测定几个样品的缺点。通过与国家规定的标准方法进行对比实验,结果表明,仪器测定的结果与标准法测定的结果具有良好的可比性,COD速测仪在企业污水排放监测中具有实际意义。

Luobei Environmental Monitoring Stationadopt the TL-1(A) type waste water quick determining instrument to determine chemical oxygen demand in enterprise exhaustwaste water, the method is in strong acid materials ,compounding catalytic agent, dissolving water sample for ten minutes only,operation simplely ,work efficiency highly ,overcoming potassium dichromate method'shortcomings of consuming time long ,every can measuring a few samples at the same time.we get the result by way of contrasting experiments with standard method that nation provides, the result expresses, instrument measurement of result and standard method measurement of result have the good comparision,the quick determining instrument to determine chemical oxygen demand have the actual meaning in enterprise exhaust waste water monitor.
