Problems solved by technology

[0002] The flocculation reactor is a device in which the coagulant reacts with tiny suspended solids and colloidal particles in the water after the coagulant is added to the water, and the small particles flocculate and agglomerate to grow into large particles. Plate reaction tank, swirl reaction tank, etc. These technologies have the disadvantages of uneven water flow velocity, long flocculation reaction time (15-20 minutes), and poor flocculation effect.
There are also grid reaction tanks and vortex reaction tanks (such as the disclosed technical scheme of CN2443950Y) etc. recently researched and developed. The former can produce some micro-eddy currents, and the flocculation reaction effect is better, but the flocculation reaction time is still relatively long (10 to 15 minutes). , the latter can generate more micro-vortexes, the flocculation reaction effect is better, and the flocculation reaction time is shorter (5-8 minutes), but there is a possibility of channel blockage, especially when biological slime is more likely to be blocked

Embodiment Construction

[0024] figure 1 The packing type flocculation reactor shown includes a shell 1, a flocculation reaction chamber inside the shell 1, an inlet pipe 3 and an outlet pipe 5 respectively arranged at opposite ends of the reaction chamber, and the reaction chamber is composed of filler 2.

[0025] The filler 2 is filled or installed in the housing 1, the water inlet distribution device 4 is connected with the water inlet pipe 3 at the lower part of the filler 2, and the outlet water distribution device 6 is connected with the water outlet pipe 5 at the upper part of the filler 2.

[0026] The shell can be made of various materials such as concrete, steel, plastic, glass fiber reinforced plastics or their combination, and the shape can be a cylinder, a cube, a cone, a sphere, etc. or their combination. Housings of different shapes and volumes can be combined in series or in parallel.

[0027] The filler is made of organic materials such as plastics, fiberglass, rubber, or inorganic m...
