Embodiment 1

[0019] Such as image 3 Shown is an improvement of the present invention, the water inlet of the tank 1 has a buffer bucket 3, so that the degree of turbulence of the sewage entering the tank 1 is weakened to a certain extent, and the sedimentation tank can be better Play a role.

Embodiment 2

[0021] Such as Figure 4 Shown is another improvement of the present invention, the upper end of the cross-section of the box body 1 is equal in width, and the lower end is an isosceles trapezoidal shape whose width gradually decreases, wherein the angle between the extension lines of the two waist sides is 90°. This structure It is conducive to the rapid precipitation of suspended particles in wastewater.

[0022] In addition, through practical application experiments, it is found that after the wastewater enters the sedimentation tank and passes through a screen 2, the turbulent state of the wastewater has basically disappeared. 5 sieves 2 can meet the requirements. When there is enough sediment at the bottom of the box body 1 during use, it is convenient and practical to just dig out most of the sediment without thoroughly cleaning.

Abstract

The invention relates to a non-turbulence sediment box which comprises a box body and a plurality of screens, wherein the screens are of a layered structure, and comprise a sponge layer, two pieces of coarse filter gauze respectively attached to the two surfaces of the sponge layer, and two wire meshes respectively attached to the outer surfaces of the two pieces of coarse filter gauze; the apertures of the screens are larger than the sizes of ceramic particles in the sewage; the screens are detachably arranged on the box body by being vertical to the direction of water flow. The non-turbulence sediment box has the beneficial effects that the sediment box is small in occupied land area, and is capable of effectively eliminating the turbulent condition so as to enable the suspended particles in the waste water to be rapidly precipitated, so that the upper layer water is good in quality; during recycling, a polished piston rod is not influenced by the tiny solid ceramic particles in the water; when the precipitate at the bottom of the box body is enough, only most precipitate is dug out, and the sediment box does not need to be thoroughly cleaned, so that the non-turbulence sediment box is convenient and practical.

Description

technical field [0001] The invention relates to a sewage treatment device. Background technique [0002] A large amount of water is required to polish the sprayed parts. The water after grinding contains a large amount of heavy metal compounds and cannot be directly discharged into the sewer. Two large sedimentation tanks are required, one for water intake and the other for sedimentation. The upper layer of water is used again so that the water resources can be used again, and the floor area is relatively large. We have tested that the sedimentation speed is 40mm per hour under static conditions, and there is no obvious sedimentation effect after a day of sedimentation when there is turbulence. Even if the degree of turbulence is small, since the large pool cannot be covered, the wind will blow the water surface, and the pumped water still contains tiny solid ceramic particles, which is unfavorable for polishing the piston rod. If the filter method is adopted, the cost wil...
