Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a self-adaptive sewage treatment stirring tank.
Background
The sewage treatment method comprises a physical treatment method, a chemical treatment method and a biological treatment method. The chemical treatment method is a wastewater treatment method for separating and removing pollutants in a dissolved and colloidal state in wastewater or converting the pollutants into harmless substances through chemical reaction and mass transfer. In the chemical treatment method, the treatment units based on chemical reaction generated by adding medicaments are as follows: coagulation, neutralization, redox, and the like.
Compared with other physical and chemical methods, the coagulating sedimentation process has the advantages of good effluent quality, stable and reliable process operation, economy, practicality, simple and convenient operation and the like. The principle of coagulating sedimentation is that by adding some medicaments (generally called coagulant and coagulant aid) into water, particles which are difficult to precipitate in the water can be polymerized with each other to form colloid, and then the colloid is combined with impurities in a water body to form larger floccule. The flocculating constituent has strong adsorption capacity, can adsorb suspended matters, and can adsorb partial bacteria and soluble substances. The flocs sink down by increasing their volume through adsorption. The coagulation process includes a mixing stage and a flocculation stage. In the mixing stage, the coagulant is quickly and uniformly distributed in water through quick stirring; the flocculation stage is to make the destabilized colloidal particles gradually increase in a mode of heterodromous flocculation and homodromous flocculation, the stirring strength is gradually reduced along with the increase of the flocculating constituent, and a certain flocculation action time is kept, so that the flocculating constituent can be stably increased to improve the coagulation effect.
The following facts exist in the stirring tank used in the current coagulation process:
(1) the transmission device is generally a gear rack, a nut screw and the like, and the structure is difficult to adapt to the working condition of sewage treatment, so that the service life of the stirring tank is short;
(2) in the current coagulation process, a coagulation medicament is prepared by mixing equipment, namely a coagulant is dissolved into a solution by water, then the coagulation medicament is added into water in a mixing tank for rapid stirring and mixing, and finally the mixture is transferred into a flocculation tank for slow stirring and flocculation; the current stirring tank can not automatically reduce the stirring speed according to the generation of flocculating constituents in the coagulation process.
