Description

Technical Field

[0001] The utility model relates to the technical field of laboratory waste liquid, and more specifically, to a laboratory waste liquid sedimentation device. Background Art

[0002] When conducting biological or chemical experiments in the laboratory, a large amount of chemical reagents are used, and accordingly, a large amount of experimental waste liquid is also generated. Generally, the waste liquid has chemical properties, and if it is directly discharged without treatment, it is easy to cause environmental pollution. Therefore, the waste liquid needs to be treated by a sedimentation device, but the existing sedimentation device usually pours the waste liquid directly when in use, which will cause the waste liquid to splash.

[0003] After searching, a Chinese patent with publication number CN213609945U discloses a laboratory sedimentation treatment device. The advantage of this structure is that by setting up a multi-stage sedimentation tank with a gradually decreasing bottom height, and allowing the experimental wastewater to flow through each sedimentation tank in turn, the separation effect of solid particles and aqueous solution in the wastewater can be improved, thereby preventing the water phase discharged from the overflow port or the drain port from clogging the external waste liquid collection device such as the wastewater pipe network. At the same time, it is also convenient to regularly clean up the solid waste at the bottom of each sedimentation tank, thereby greatly reducing the labor intensity of laboratory wastewater treatment; in addition, by setting up a screen and a cleaning part for carrying the parts to be cleaned, it is convenient to clean the experimental utensils waiting for cleaning, and it is convenient to treat the wastewater generated by the cleaning, and it can also effectively prevent splashing when pouring wastewater into the primary sedimentation tank.

[0004] However, in actual use, since the waste liquid is likely to contain more chemical components and the settled waste liquid is directly discharged through the drain and overflow ports, the chemical components in the waste liquid may easily pollute the surrounding environment.
