Abstract

A sludge treatment settling pond relates to structural improvement of the sludge treatment settling pond. The invention provides the sludge treatment settling pond, which is simple in structure and convenient to use, can increase the density of the sludge and can reduce the water content of the sludge. The sludge treatment settling pond provided by the invention comprises a pond body, a bottom plate, a settling tank, an inner side wall, an outer side wall, a water discharging port, a medicine adding port and liquid dripping holes, and is characterized in that the pond body consists of the bottom plate, the inner side wall and the outer side wall; the settling tank is arranged in the pond body; the water discharging port is formed in the outer side wall; and the liquid dripping holes are formed in the bottom plate.

Description

technical field [0001] The invention relates to an improvement of the structure of a sedimentation tank for sludge treatment. Background technique [0002] Sludge is the product of sewage treatment, which is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. [0003] A sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. It has many types, which can be divided into three types: advection type, vertical flow type and radial flow typ...
