[0004] The above-mentioned flocculation device has good flocculation effect and fast flocculation speed. It is placed at the front of the flocculation tank. Before the raw water enters the flocculation tank for flocculation, the medicine can be fully mixed with the suspended matter in the flocculation device, and the collision probability of the flocs is enhanced to form a better The flocculation crystal nucleus lays a good foundation for subsequent flocculation, but this flocculation device is only suitable for raw water with low sand content. For raw water with high sand content, a pre-sedimentation tank needs to be added to remove sand particles with large particle sizes in the raw water. The pre-sedimentation tank occupies a large area and investment, which greatly increases the cost of water purification

The invention provides a flocculating core device and a water treatment system. The flocculating core device comprises a cylindrical inner wall, a cylindrical outer wall and a water inlet pipe, a sidewall of a flocculating core cavity is defined by the side wall, the outer wall and the inner wall are coaxially arranged, a side wall of a precipitating cavity is defined by the outer wall and the inner wall, the water inlet pipe supplies water to the precipitating cavity from the upper end of the precipitating cavity, the water inflow direction is perpendicular to the radial direction of the precipitating cavity, and the flocculating core cavity is communicated with the precipitating cavity at the bottom part. The water treatment system comprises the flocculating core device and a flocculentprecipitating pond, and a water outlet of the flocculating core device is communicated with a water inlet of the flocculent precipitating pond. According to the flocculating core device and the watertreatment system, sand in raw water is separated after the raw water is precipitated through the precipitating cavity, then the raw water is flocculated in the flocculating core cavity, the flocculating core effect is good, the flocculating core speed is high, different requirements on water quality are met, and the flocculating core device occupies a small area and is low in cost.
Description
technical field [0001] The invention relates to the technical field of water purification and treatment, in particular to an improved flocculation core device and a water treatment system constructed by the same. Background technique [0002] The flocculation tank that completes the flocculation process occupies an important position in water purification. The particle size of suspended substances and colloidal substances in natural water is very small. In order to remove these substances, usually by means of coagulation, that is, adding an appropriate coagulant to the raw water, and after thorough mixing, the colloidal stability is destroyed (destabilized). And it is adsorbed with the polymer hydrolyzed by the coagulant, so that the particles have flocculation performance. The purpose of the flocculation tank is to create suitable hydraulic conditions to make the particles with flocculation properties aggregate in contact with each other to form larger flocs. [0003] The...
