Description

Rapid and efficient coagulating sedimentation equipment for sewage coagulating sedimentation tank

Technical Field

The invention belongs to the technical field of sewage treatment, and particularly relates to a fast and efficient coagulating sedimentation device for a sewage coagulating sedimentation tank.

Background

Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people. The coagulating sedimentation tank for sewage treatment is mainly used for removing granular impurities in sewage treatment, and has important significance and position in sewage treatment.

The coagulating sedimentation principle is a water treatment method in which colloids and fine suspended matters in wastewater are coagulated into floccules under the action of a coagulant and then separated and removed.

The coagulation method is based on the principle that coagulant is added into waste water, and the coagulant is electrolyte, so that micelle is formed in the waste water and is electrically neutralized with colloid substances in the waste water to form fluff grains for settlement. The coagulating sedimentation can remove not only fine suspended particles with the particle size of 10 < -3 > to 10 < -6 > mm in the wastewater, but also rich nutrient substances such as chromaticity, oil content, microorganisms, nitrogen, phosphorus and the like, heavy metals, organic matters and the like.

Before the coagulant is added into the wastewater, the colloid and fine suspended particles in the wastewater have light mass and are collided by the molecular thermal motion of water to make irregular brownian motion. The particles all carry like charges, and electrostatic repulsion among the particles prevents the particles from approaching each other and polymerizing into larger particles; secondly, the charged colloidal particles and counter ions can be hydrated with the surrounding water molecules to form a hydrated shell, and the polymerization of each colloid is hindered. The more charged the colloidal particles of a colloid, the greater its potential; the more counter ions in the diffusion layer, the greater the hydration, and the thicker the hydration layer, and thus the thicker the diffusion layer, the greater the stability.

After the coagulant is added to the waste water, the colloid is reduced or eliminated in potential, and the stable state of the particles is destroyed (called destabilization). The process of aggregation of destabilized particles into each other into larger particles is called agglomeration. Unstabilized colloids can also form large particles, a phenomenon known as flocculation. Different chemicals can destabilize, coagulate or flocculate colloids in different ways. The flocculating constituent has strong adsorption capacity, and can adsorb suspended matters, partial bacteria and soluble substances. The flocs sink down by increasing their volume through adsorption.

However, in the existing sewage treatment process, some coagulant is put into sewage in a manual mode, so that the coagulant is unevenly put, the coagulation and flocculation of impurities in the sewage are not facilitated, the sewage treatment effect is poor, the labor intensity of workers is high, time and labor are wasted, the development and the implementation of sewage treatment work are not facilitated, and the production and the life of people are not facilitated; the conventional coagulant adding equipment can achieve the aim of uniform adding only by adding actions for many times, and has long time consumption and low efficiency. After the coagulant is put into the sewage, the coagulant and the sewage are not sufficiently mixed, the reaction efficiency is reduced, and when the sewage is discharged outwards, sundries deposited at the bottom of the sedimentation tank are possibly brought out through water flow, so that the sundries enter the next procedure, and the whole sewage purification effect is influenced. Because the existing coagulating sedimentation equipment can not fully and efficiently mix the sewage and the coagulant, the sewage treatment efficiency is not high, the treatment time is prolonged, and the treatment effect is not good.
