技术领域technical field
本发明涉及污水处理设备技术领域，具体涉及一种用于循环养殖污水处理的紫外线杀菌装置。The invention relates to the technical field of sewage treatment equipment, in particular to an ultraviolet sterilizing device used for circulating aquaculture sewage treatment.
背景技术Background technique
紫外线杀菌技术是一种利用紫外灯产生的紫外线进行辐射以达到杀菌效果的杀菌技术。当微生物处于紫外线照射时，紫外光被微生物的核酸所吸收。一方面可使核酸突变，使其无法复制、转录，阻碍蛋白质的合成；另一方面产生自由基，引起光电离，从而导致细胞的死亡，由此达到杀菌的目的。该杀菌技术效率较高、安全、无二次污染、费用低、可连续工作，已在我国的水产养殖中得到了较为广泛的应用。Ultraviolet sterilization technology is a sterilization technology that uses ultraviolet rays generated by ultraviolet lamps to radiate to achieve sterilization effects. When a microorganism is exposed to ultraviolet light, the ultraviolet light is absorbed by the nucleic acid of the microorganism. On the one hand, it can mutate nucleic acid, making it unable to replicate and transcribe, and hinder protein synthesis; on the other hand, it can generate free radicals, cause photoionization, and lead to cell death, thereby achieving the purpose of sterilization. The sterilization technology has high efficiency, safety, no secondary pollution, low cost, and continuous work, and has been widely used in aquaculture in my country.
在现今的循环养殖中，紫外线杀菌主要以将紫外杀菌灯管直接安装在水体中进行杀菌或者在待杀菌水体的上方安装紫外灯进行辐射杀菌。这些方法在使用中，存在一些不足。紫外线消毒效果与灯管和水的透射率以及照射时间有关。待杀菌的水体的管道横截面积大，水体的流速快，紫外灯的杀菌效果受到了明显的制约。紫外线杀菌技术的杀菌效果还跟紫外灯的辐射强度有直接的关系，辐射强度越大，杀菌的效果越好，但是过大的辐射强度会带来电能的浪费。所以，在不增加的紫外灯辐射强度的情况下，需要一种更加高效的杀菌装置。In today's circulating culture, ultraviolet sterilization is mainly to install ultraviolet germicidal lamp tubes directly in the water body for sterilization or install ultraviolet lamps above the water body to be sterilized for radiation sterilization. There are some deficiencies in these methods in use. The ultraviolet disinfection effect is related to the transmittance of the lamp tube and water and the irradiation time. The cross-sectional area of the water body to be sterilized is large, and the flow rate of the water body is fast, so the sterilization effect of the ultraviolet lamp is obviously restricted. The sterilization effect of ultraviolet sterilization technology is also directly related to the radiation intensity of the ultraviolet lamp. The greater the radiation intensity, the better the sterilization effect, but excessive radiation intensity will cause waste of electric energy. Therefore, there is a need for a more efficient sterilizing device without increasing the radiation intensity of the ultraviolet lamp.
