Description

Technical Field

[0001] The utility model relates to the technical field of flocculation devices, in particular to a flocculation device for treating chemical wastewater. Background Art

[0002] Chemical wastewater refers to process wastewater, cooling water, washing water and other wastewater discharged in chemical production. If these wastewaters are discharged without treatment, they will cause different properties and different degrees of pollution in the water body, thus endangering human health. The main ways to solve chemical wastewater are source control and end-of-pipe control. Due to the limited level of domestic chemical production technology, there are inevitably washing, distillation and other processes in the product production process, which are difficult to change in the short term. Therefore, the most important way to solve wastewater is to treat it from the end, that is, to treat production wastewater. The flocculation process is one of the important processes in the wastewater treatment process. It refers to making the suspended particles in water or liquid aggregate and enlarge, or forming flocs, thereby accelerating the coagulation of particles and achieving the purpose of solid-liquid separation.

[0003] After searching, such as the patent with application number CN202321299082.5, the utility model provides a flocculation device for chemical wastewater treatment, including a flocculation tank, wherein the flocculation tank is connected to a water inlet pipe on one side near the top, and the flocculation tank is connected to a drain pipe on the other side near the bottom, and the drain pipe is connected to a first valve, and a feeding assembly is arranged above the water inlet pipe, and a driving assembly is arranged on both sides of the flocculation tank, and a cleaning assembly is arranged between the two driving assemblies. In the utility model, the cleaning assembly and the driving assembly are arranged for use, and the driving assembly drives the cleaning assembly to move horizontally, and two inclined scrapers are used to scrape off the flocculants on the inner walls on both sides of the flocculation tank, and the scraped flocculants float in the chemical wastewater and are intercepted by the interception wire mesh plate. The flocculants after interception are attached to the interception wire mesh plate, and the excess flocculants can be further collected and intercepted by the arc-shaped aggregate mesh plate, so that the flocculants inside the chemical wastewater can be quickly collected and collected, thereby improving the cleaning efficiency of the flocculants. However, in actual use, the above patent has the following defects: the coagulant is mixed into the sewage only through a high-speed water flow, resulting in a low mixing efficiency of the flocculant and the chemical wastewater and a long mixing time, which greatly affects the efficiency of wastewater flocculation.
