As shown in figures 2 and 3, the bottom of the first-stage sedimentation tank is provided with a slope 12 which inclines downwards from the tank wall with the water inlet to the middle of the tank bottom.
A vertical slot 13 is arranged between the other two opposite tank walls of the first-stage sedimentation tank 1, a clapboard 14 is movably arranged in the slot 13 to divide the first sedimentation tank into two areas from the middle, and the area without slope at the bottom of the tank is a sedimentation area. The baffle is not installed at ordinary times, and the sediment in the sedimentation zone is accumulated to a certain thickness, and the first sedimentation tank is separated by the installation baffle, and the silt in the sedimentation zone is salvaged and removed and then the baffle is taken out.
As shown in figure 1, the utility model discloses a reduce to take up an area of, compact structure, first order sedimentation tank 1, second level sedimentation tank 2, third level sedimentation tank 3, fourth level sedimentation tank 4 are "field" font setting, and fifth level sedimentation tank 5, sixth level sedimentation tank 6, seventh level sedimentation tank 7 set up side by side.
The utility model discloses an all sedimentation tanks all excavate in the below ground, for guaranteeing safety, are provided with guardrail 15 around all sedimentation tank regions.
The utility model discloses specific embodiment as follows:
the position of the sedimentation tank is selected according to the actual situation of a construction site, the volume of the sedimentation tank is required to meet the requirement of staying for thirty minutes of wastewater amount, the depth of the sedimentation tank is generally 1.5-2 m, and the length and the width can be determined according to the site geology, the wastewater amount, the rainfall situation and the site land situation.
