1st, the control light source 34 of control chamber 6 and photoreceiver 35 are powered and open simultaneously, and by water inlet pipe 330 water sample is passed through, In detector, water sample is flowed out by the exit of outlet pipe 332；

2nd, gases at high pressure are passed through into the second air inlet 312 and the first air inlet 311, gases at high pressure are logical by the second air inlet Road 3121 is sprayed by the second gas outlet 3120, and gases at high pressure spray towards the outlet of outlet pipe 332, and the dirts such as silt are utilized into high pressure Gas pushes away；Gases at high pressure are sprayed by the first inlet channel 3111 by the first gas outlet 3110, can by hydraulic pressure it is too high when spray Water column to light source 34 or photoreceiver 35 is pressed downward, it is to avoid light source 34 or the contamination dirt and water stain of photoreceiver 35；

3rd, light source 34 launches light to outlet pipe 332, and light completely penetrates through the water sample in outlet pipe 332, and exposes to light On quick receptor 35, photoreceiver 35 will transmit through the light of water sample and carry out the detection of intensity of illumination, converse the printing opacity of water sample Degree；

4th, the bottom of lower cover 32 is flowed to by the water sample flowed out in outlet pipe 332, and is flowed out from the outlet 320 of bottom, it is complete Into water quality transmittance detection process.

Therefore in control aspect, the above-mentioned dyeing waste water for coming sampling first passes through sedimentation device precipitation, the supernatant after sedimentation Liquid sends into the transmittance detector 3 for detecting dyeing waste water supernatant transparent luminosity, and the light of light source 34 is by first passing through first The air in overboard gap, then through the water in outlet pipe 332, then the air that printing opacity is crossed in the second overboard gap, final incident light Quick receptor 35, this structure setting can avoid the water column out of outlet pipe 332 from flowing to light source 34 or photoreceiver 35, protect Shield light source 34 and photoreceiver 35 exempt from water stain and dirt and are infected with and affect translucent effect, improve the stability and accurately of detection Property.Above-mentioned photoreceiver 35 is that the optical signal pick-up that will be detected is sent into the signal of telecommunication, the signal sent typically directly and The milliampere level signal of telecommunication of the matching of control chamber 6.

Control chamber 6 according to send into the signal of telecommunication, feedback regulation is carried out to the first motor-operated control valve 7b, with adaptive change its It is that its clarity is judged by optical signal in aperture, i.e. transmittance detector 3, so as to control chamber 6 according to clarity controlling the The aperture of one motor-operated control valve 7b so that decolorising agent addition is reasonable so that dyeing waste water is stablized, fully flocculated in sedimentation tank. Specifically, the irradiation of light source 34 outlet pipe 332, if supernatant flocculation is complete, photoreceiver 35 receives stronger light letter Number, if not flocculating or fully not flocculating complete, photoreceiver 35 receives stronger optical signal to be weakened.
