摘要
本发明公开了水质COD的光谱测量装置,流通池固定在遮光箱中,至少两面透光,光源固定在遮光箱内表面,探测器固定在光源垂直正下方的遮光箱内表面;第一、二样品池设置于遮光箱外,第一水管连通流通池和待测水样,第二水管连通流通池和第一样品池,第三水管连通流通池和第二样品池,第四水管连接流通池底部出水口和遮光箱外界,其上设有蠕动泵,第五水管连接流通池顶部和遮光箱外界,所述单片机用于控制所有装置。并公开了使用该装置来测量水质COD的光谱测量方法。本发明可以快速准确的测量水质COD,且可以循环自动在线测量,吸收光谱比一般方法中直接测量蒸馏水配制的硝酸盐溶液、阴离子表面活性剂光谱更加接近实际水样情况。

摘要_en
The invention discloses a water quality COD spectral measurement device. A flow-through cell is fixed in a shading box and at least two surfaces of the flow-through cell are nonopaque; a light source is fixed in the internal surface of the shading box; a detector is fixed on the internal surface of the shading box under the light source; a first sample cell and a second sample cell are arranged outside the shading box; a first water pipe is communicated with the flow-through cell and a to-be-measured water sample; a water pipe is communicated with the flow-through cell and the first sample cell; a third water pipe is communicated with the flow-through cell and the second sample cell; a fourth water pipe is connected with a water outlet in the bottom of the flow-through cell and the external part of the shading box; a peristaltic pump is arranged on the fourth water pipe; a fifth water pipe is connected with the top of the flow-through cell and the external part of the shading box; a single-chip microcomputer is used for controlling all devices. The invention further discloses a spectral measurement method for measuring the water quality COD by adopting the water quality COD spectral measurement device. The water quality COD spectral measurement device can quickly and accurately measure the water quality COD and can perform online measurement in a circulatory and automatic manner; the absorption spectrum is closer to the actual water sample condition as compared with the spectrum used for directly measuring nitrate solution prepared from distilled water and an anion surfactant.
