| abstract | (57) [Abstract] [Purpose] To improve the ventilation efficiency in the drainage permeation pipe and improve the air permeability, and to develop a household wastewater treatment device that is simple in operation and inexpensive in operating cost. [Structure] In the household wastewater treatment device of the present invention, a drainage permeation pipe 3 having a large number of small holes 3a is connected after an oil / water separation tank 1 and a branching tank 2, and a crushed stone layer S is formed around the pipe. In the treatment device, at least two rows or more of drainage permeation pipes 3 are connected in parallel to the branch tank 2, and at least two ventilation pipes 4 are connected to the front and rear of the drainage permeation pipes 3 and the ventilation pipes 4 are connected. One of the heads is formed with a squeezing portion 5 which causes an intake action in the drainage permeation pipe by natural ventilation. |
