Coagulating sedimentation separator

Abstract

The invention provides a coagulating sedimentation separator, which comprises a casing, a water outlet groove in the casing, a water outlet pipe connected with the water outlet groove, a chemical adding device, a chemical adding pipe, a water inlet pipe and a mud discharging pipe on the casing. The coagulating sedimentation separator is characterized in that the water outlet groove is annular and fixed on the upper portion inside the casing, an inner ring groove wall of the annular water outlet groove is a permeable material filtering wall, an outer ring groove wall is a lateral wall of the casing, a central drum body with a sealed bottom end is arranged below the water outlet groove, and the bottom of the central drum body is arranged on a support in the casing. The chemical adding device comprises a first chemical adding device and a second chemical adding device, the first chemical adding device is fixed on the bottom inside the central drum body, the second chemical adding device is fixed on the upper portion inside the central drum body, and a water outlet end of the water inlet pipe is arranged at the bottom inside the central drum body. The coagulating sedimentation separator finishes coagulating, sedimentation, filtering and absorbing effects in the same tank body and is reasonable and compact in structure, good in outlet water quality, high in treating efficiency, low in operation cost, strong in adaptation and easy to operate and manage.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a coagulation sedimentation separator. Background technique [0002] Coagulation technology occupies an important position in water treatment, whether it is water supply treatment or wastewater treatment, especially the treatment of difficult-to-treat industrial wastewater, whether it is secondary treatment or advanced treatment, as long as the water contains colloidal substances that cannot be separated by natural precipitation Most of the substances that are easy to form a stable system are treated by coagulation technology, or a combination of coagulation technology and other technologies. At present, the coagulation and sedimentation facilities used at home and abroad have the following problems: (1) In order to ensure the effect of mixing and reaction, mechanical stirring is required, which increases the power consumption of operation; (2) In order to ensure the effe...

AI Technical Summary

Problems solved by technology

At present, the coagulation and sedimentation facilities used at home and abroad have the following problems: (1) In order to ensure the effect of mixing and reaction, mechanical stirring is required, which increases the power consumption of operation; (2) In order to ensure the effect of water discharge, sufficient settling time is required , resulting in a huge structure; (3) unreasonable dosing of chemicals, resulting in low utilization of chemicals and waste; (4) greatly affected by water quality fluctuations; (5) single function, low processing efficiency; (6) high intensity of operation and management, etc.
