A kind of related drainage arrangement with blowdown and full row function of this creation system,It includes an ontology,The inside of the ontology sequentially includes by Zuo Zhiyou: one first filtering area,One first storage transition region,One second filtering area,One second storage transition region,Third filtering area and a drainage area,Wherein first filtering area is equipped with first partition,There is a second partition between first filtering area and the first storage transition region again,There is a third partition between the first storage transition region and the second filtering area,There is one the 4th partition between second filtering area and the second storage transition region again,There is one the 5th partition between the second storage transition region and third filtering area,There is between the third filtering area and drainage area one the 6th partition again； Its characteristic is in what: an at least connectivity structure,The connectivity structure system can install the bottom of what third partition and the 5th partition respectively,The third partition and the 5th partition are equipped with communication port,It is equipped with hollow portion in the connectivity structure again,The connectivity structure is to having two openings. By being that the water in fish jar quickly can be discharged with dunghill using connecting pipe principle and siphon pipe principle, each region in fish jar is formed into individual section with air screen barrier principle, carries out the work of various arrangements, maintenance to lower cylinder with benefit.本創作係有關一種具有排汙及全排功能之排水裝置，其包含一本體，該本體之內部由左至有依序包括有：一第一過濾區、一第一貯存過渡區、一第二過濾區、一第二貯存過渡區、第三過濾區及一排水區，其中該第一過濾區設有第一隔板，又該第一過濾區與該第一貯存過渡區之間具有一第二隔板，該第一貯存過渡區與第二過濾區之間具有一第三隔板，又該第二過濾區與第二貯存過渡區之間具有一第四隔板，該第二貯存過渡區與第三過濾區之間具有一第五隔板，又該第三過濾區與排水區之間具有一第六隔板；其特徵在於：至少一連通結構，該連通結構係可分別裝設於第三隔板與第五隔板之底部，該第三隔板與第五隔板設有連通口，又該連通結構內設有中空部，該連通結構向下設有兩開口。藉由係利用連通管原理與虹吸管原理，可將魚缸內之水與污穢物進行快速的排出，與氣屏障原理將魚缸內之各區域形成獨立區段，以利對下缸進行各種整理、保養的工作。
