technical field

The invention belongs to the technical field of sewage flocculation, in particular to a pool for sewage flocculation and scraping and cleaning equipment.

Background technique

In sewage treatment, after the flocculant is added to the water, the impurity particles in the water will first lose stability under the action of the flocculant, and then coagulate into larger particles, and then settle down or float up in the separation facility. Rapid stirring after dosing can promote the chance and number of collisions between colloidal impurity particles and micelles hydrolyzed by flocculant in sewage treatment.

The current flocculation process also has the following problems:

Sewage pools are generally open-air, and some sewage will produce toxic or odorous gases.
