Microorganism throwing device and trash cleaning ship

The utility model belongs to the technical field of sewage treatment, and particularly relates to a microorganism feeding device and a sewage disposal ship using the microorganism feeding device. The discharge pipe is communicated with the metal tank and is arranged below the metal tank, when microorganisms are added, the metal tank is immersed in water of the treatment tank, the hollow rubber ball blocks the material opening through buoyancy, the microorganisms and growth liquid of the microorganisms are added into the metal tank, the temperature of the growth liquid can be slowly synchronized with that of sewage, and then the microorganisms and the growth liquid are added into the treatment tank. And death caused by rapid change of temperature when microorganisms are added can be avoided. The microorganism feeding device and the sewage disposal boat using the same are particularly suitable for outdoor sewage treatment projects. 本实用新型属于污水处理技术领域，具体为一种微生物投放装置及使用该微生物投放装置的清污船。通过设置出料管与金属槽连通并置于其下方，在添加微生物时先使金属槽浸入在处
