Yellow mud activating and adding apparatus for water purification and clarification tank

Abstract

The invention relates to a yellow mud activating and adding apparatus for a water purification and clarification tank. The yellow mud activating and adding apparatus comprises a mud stirring machine (1), a mud filtration screen grate (2), an activation mud storage box (3), a stirrer (4), and a mud pump (5). The mud filtration screen grate (2) is installed between a mud outlet of the mud stirring machine (1) and the activation mud storage box (3). The stirrer (4) is installed on the activation mud storage box (3). An inlet of the mud pump (5) is connected with a mud outlet of the activation mud storage box (3). An outlet of the mud pump (5) is communicated with a water inlet of the water purification and clarification tank by a mud pipeline (6). With adopting the apparatus of the present invention, labor consumption is less during the yellow mud activating and adding process, the activation degree of the yellow mud can be substantially improved, the activation effect is good, the activation time for the yellow mud can be shortened. In addition, the low-turbidity water additive is not adopted, such that the water treatment cost is reduced, and the water treatment effect is increased.

Description

technical field [0001] The invention relates to a clarification tank of a water treatment system, in particular to a yellow mud activation adding device for the clarification tank. Background technique [0002] The clarifier is a structure that integrates the flocculation reaction process and the clarification and separation process in the raw water treatment process. In the clarifier, the sediment is lifted up and in a uniformly distributed suspension state, forming a high-concentration stable active sludge layer in the clarifier, and the suspended matter concentration of this layer is about 3-10g / L. The raw water flows from bottom to top in the clarifier, and the sludge layer can be in a dynamic equilibrium state in the rising water flow due to gravity. When the raw water passes through the active sludge layer, the suspended solids in the raw water are blocked by the active sludge layer by using the principle of contact flocculation, so that the water is clarified, and th...

AI Technical Summary

Problems solved by technology

Manually adding yellow mud consumes a lot of manpower, and the activation degree of yellow mud is low, so the effect is not good

Low turbidity water additives are expensive and require activation treatment before adding them. Adding low turbidity water additives will greatly increase the cost of water treatment
