Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a flocculation reaction pool grid bar. Background Art

[0002] The particle size of suspended matter and solid matter in natural water is very small. In order to remove these substances, coagulation is usually used. That is to say, appropriate coagulants are added to the raw water. After sufficient mixing, the colloid stability is destroyed (destabilized) and adsorbed with the polymer phase after the coagulant water medium, so that the particles have flocculation properties. The purpose of the flocculation reaction tank is to create suitable hydraulic conditions to make the particles with flocculation properties aggregate in mutual contact to form larger floccules (flocs). Therefore, whether the flocculation reaction tank is designed properly is related to the flocculation effect, and the flocculation effect directly affects the sedimentation effect of subsequent treatment.

[0003] In order to improve the flocculation effect, many township water plants currently use grid plate (or bar) flocculation reaction tanks. Most of the grid plates are square grids, and there are also circular grids. There are horizontal and vertical partitions between the grids. The width of the partitions is between 10-35 mm, the width of the bar plate is between 35-50 mm, and the interval between the bar plates is between 50-80 mm. After the flocculation reaction tank has been running for a period of time, flocculants will accumulate on these grids and bar plates. When the inlet flow rate fluctuates greatly, these accumulated flocculants will fall into the water body under the influence of hydraulic conditions, directly affecting the sedimentation and filtration effect of subsequent treatment and affecting the effluent water quality. For this reason, we propose a flocculation reaction tank bar. Utility Model Content
