AI Technical Summary

Technical Problem

Coal yard sewage contains a large amount of suspended substances, heavy metals, oils and other pollutants. Direct emissions will pollute soil and water bodies, destroy ecosystems, and affect the survival and development of organisms.

Method used

A coal yard water treatment dosing system is designed, including a first dosing unit for adding coagulant, a second dosing unit for adding coagulant, and a flocculation tank for completing flocculation and precipitation. The impurity treatment of the sewage is completed by transporting the sewage to the dosing unit separately, adding coagulant and coagulant, and finally transporting it to the flocculation tank.

Benefits of technology

Through this system, impurities in coal yard sewage are effectively removed, and the sewage is purified, reducing environmental pollution and protecting ecosystems and water resources.

Abstract

The invention discloses a coal yard water treatment dosing system, comprising: a first dosing unit for adding a coagulant; the second dosing unit is used for adding a coagulant aid; the first storage unit is used for storing the sewage added with the coagulant in the first dosing unit; the second storage unit is used for storing the sewage added with the coagulant aid in the second dosing unit; and the flocculation basin is connected with the first storage unit and the second storage unit. Sewage of a coal yard is respectively conveyed into the first chemical adding unit and the second chemical adding unit, a coagulant and a coagulant aid are respectively added into the first chemical adding unit and the second chemical adding unit, and finally the sewage added with the coagulant and the sewage added with the coagulant aid are conveyed into the flocculation basin through a pipeline. Flocculation and sedimentation are completed in the flocculation basin, so that impurity treatment of the sewage of the coal yard is completed.
