Description

Annular array light source for microorganism detection Technical Field The utility model belongs to the technical field of array light sources, and particularly relates to an annular array light source for microorganism detection. Background With the rapid advancement of the urban process, the urban sewage discharge amount is in a continuously rising state, and the sewage treatment plant is subjected to increasingly heavy operation load. At present, an activated sludge process is used as a mainstream technology for urban sewage treatment, and a core mechanism of the activated sludge process is to rely on physical, chemical and biological reactions caused by various microorganisms in sewage to effectively remove organic matters in the sewage. In view of the fact that the main body of the activated sludge system is composed of microorganism groups, the diversity and the abundance of microorganism types become key indexes for measuring sewage treatment efficiency, and the growth states of different microorganism groups directly determine the final effect of sewage purification. In the specific operation of the activated sludge process, the accurate detection of microorganisms in the activated sludge phase difference microscopic image is not only a core link for guaranteeing the effectiveness of the activated sludge sewage treatment method, but also has immeasurable significance for monitoring the running condition of a sewage treatment system in real time, promoting the sustainable development of the sewage treatment industry and strengthening the environmental protection work. In the prior art, when the microorganism in the sewage is shot through the visual detection device, different microorganisms need to be irradiated by adopting light sources with different wavelengths in order to ensure the shooting effect and clearly distinguish different microorganisms in subsequent images, so that different light quantum effects are generated by different microorganisms under the light rays with different wavelengths. However, the conventional microbial light source generally employs a linear array arrangement of light sources whose light rays are linearly distributed, and in order to secure light intensity, a plurality of illumination units are required to be closely arranged. This results in a large amount of heat being generated by the operation of the lighting unit, which affects the normal operation of the light source. Meanwhile, the traditional linear array light source irradiates directly sewage, the beam angle of the traditional linear array light source is not restricted, and the problem that the part of a finally photographed microorganism image is not clear enough exists. Therefore, the utility model discloses an annular array light source for microorganism detection, aiming at the problems of the prior array light source for microorganism detection in the sewage treatment process. Disclosure of utility model The utility model discloses an annular array light source for microorganism detection, which uniformly irradiates organisms in sewage at a specific beam angle in an annular arrangement mode and can effectively reduce the working temperature of densely arranged light sources. The utility model is realized by the following technical scheme: The annular array light source for microorganism detection comprises a substrate, wherein a plurality of integrated light sources are arranged on one side end face of the substrate along annular paths with different diameters, the integrated light sources can emit different wavelength ranges and different polychromatic light, a transparent annular cover is arranged on the outside of the integrated light sources along the annular paths, a soft light TIR lens is arranged on the transparent annular cover at a position corresponding to the integrated light sources, a water cooling disc is arranged on the other side end face of the substrate, and heat transfer elements are arranged around the integrated light sources and are connected with the water cooling disc. Through set up a plurality of integrated light sources along the annular route of different diameters on base plate one side terminal surface, constitute annular array light source structure, integrated light source can send different wavelength ranges and different polychromatic light simultaneously, and then can carry out the polychromatic domain illumination of visible spectrum to the living things in the sewage for different microorganisms produce the light quantum effect to the optic fibre of different wavelength, then can match visual detection system to shoot microorganism, with the processing state of analysis sewage. Meanwhile, the light source emitted by the integrated light source is corrected by arranging the light-transmitting TIR lens, so that the optical fiber emitted by the integrated light source irradiates at a specific diffusion angle. Because the integrated light source distance of the annular
