Problems solved by technology

However, considering that during detection, printing and dyeing wastewater is easy to contaminate the surface of the light source and light sensing element, resulting in a double decrease in light transmittance and light sensitivity. This kind of detection box is not very good in detection accuracy and stability, and it also has durability. Many problems, disassembly and maintenance are more troublesome
[0006] At the same time, how to prevent the detection box from scaling after a period of use is also a headache

Embodiment Construction

[0036] The invention will be further described below in conjunction with the accompanying drawings.

[0037] refer to Figures 1 to 9 The shown transmittance detector for detecting the transmittance of printing and dyeing wastewater includes a housing, a light source 4, a photosensitive receiver 5 and a flow multi-channel pipe 3 for the flow of water samples. in:

[0038]The flow multi-way pipeline 3 includes a water outlet pipe 32 and a water inlet pipe 30, the water inlet pipe 30 communicates with the water outlet pipe 32, the water outlet pipe 32 is a through pipe with both ends connected, the light emitting direction of the light source 4, the water outlet pipe 32 and the photosensitive receiver 5 are approximately on the same line. There is a first water-falling gap between the above-mentioned light source 4 and one end of the water outlet pipe 32 . There is a second water drop gap between the photosensitive receiver 5 and the other end of the water outlet pipe 32 . T...

Abstract

The invention discloses a water quality transparency detector for detecting the transparency of printing and dyeing wastewater. The detector comprises a casing, a light source, a photosensitive receiver and a flow pipeline, wherein the flow pipeline comprises a water outlet pipe and a water inlet pipe; the ray of the light source penetrates through the interior of the water outlet pipe and irradiates the photosensitive receiver; a second air inlet mechanism is further arranged inside the casing, and comprises a second air inlet, a second air inlet passage and a second air outlet; the second air inlet is formed in the outer wall of the casing; the second air outlet is towards the outlet of the water outlet pipe; a water outlet for a water sample to flow out is further formed in the bottom of the casing. The transparency detector has the advantages that the second air outlet can inject air to the outlet of the water outlet pipe, blow off viscous soil blocks through air pressure and prevent soil from being scaled in the position of the water outlet pipe after the water is not fed to the detector, the cleaning and maintenance frequencies are reduced, and the service life of the detector is prolonged.

Description

technical field [0001] The invention relates to water sample detection equipment, which is a light transmittance detector for detecting the light transmittance of printing and dyeing wastewater, and its use method. Background technique [0002] China is the world's largest producer and exporter of textiles and clothing, so the printing and dyeing industry is closely related to it, and the printing and dyeing industry is a large water consumer. The amount of wastewater discharged and the total amount of pollutants rank second and fourth in the national industrial sector respectively. , is one of the key industries causing water pollution in my country. Compared with polluted wastewater from other industries, printing and dyeing wastewater has the characteristics of large wastewater discharge, dark color, high content of refractory organic matter, and unstable water quality. [0003] For the treatment of printing and dyeing wastewater, the existing treatment technologies mainl...
