PROBLEM TO BE SOLVED: To cultivate aquatic plants in a washing toilet tank, make it possible to collect and fix carbon dioxide contained in the open air by utilizing operation of photosynthesis thereof, improve the natural environment and, at the same time, to also improve a residential environment. SOLUTION: The inside of a washing toilet tank main body 1 is partially divided into two parts with a partition 2, a filter 3 using activated carbon or the like is proved in one layer of them, a pipe 4 is mounted to connect with the outside, an electrically rotational fan 5 is provided in the front end thereof to take the open air in water inside of the tank 1, organic matter included thereinto is decomposed into microbes in the filter 3, and they are used as nutriment of aquatic plants 8. A temperature adjusting function attached heater 6 is mounted in the lower part of the inside of the tank 1, a light 7 is mounted in the upper part of the tank 1 to promote the growing of the aquatic plants 8, optical synthesis is activated, and the collection and fixation of carbon dioxide can be stabilized throughout the year. Since the open air passing through the water inside of the washing toilet tank main body 1 can be taken into a cleaned building through the water inside of the tank and filter 3, the improvement of the natural environment as well as the improvement of a residential environment can be made. |
