Ectopic pump circular processing system and method for reactive additives of tea saponin

Abstract

The invention belongs to the technical field of repair of environment polluted by heavy metal, and particularly relates to an ectopic pump circular processing system and method for reactive additives of tea saponin. The invention adopts the scheme that a pumping well is connected with a circular reactor through a transmission pump, and a water delivery well is connected with the circular reactor; the circular reactor is connected with a decomplexing separation and recovery reactor through two pipelines; the circular reactor and the decomplexing separation and recovery reactor are respectively connected with a dosing device; and the decomplexing separation and recovery reactor is connected with a heavy metal collector. According to the invention, heavy metal sewage reacts with the tea saponin, the tea saponin is separated from the heavy metal through heavy metal catching agent N-915, NH3-N type heavy metal precipitator or alkali in a decomplexing way, and heavy metal sewage is delivered to the heavy metal collector for sedimentation and collection. The method is suitable for processing the quality of groundwater polluted by heavy metal, outlet water after being processed has good quality, the removal rate of heavy metal is more than 96%, and main pollution indexes conform to first grade of National Comprehensive Wastewater Discharge Standard.

Description

technical field [0001] The invention belongs to the technical field of remediation of heavy metal-polluted environments, and in particular relates to a system and method for ex-situ extraction and circulation treatment of tea saponin active additives. Background technique [0002] my country is a country with a serious shortage of water resources. However, due to serious pollution, the quality of groundwater in many areas has deteriorated seriously, and it can no longer be used by industry and life. Heavy metal pollution. Heavy metals are pollutants that are difficult to control. They have a long incubation period, chronic accumulation of hazards, are not easy to be noticed by people, and are non-degradable. Once they enter the groundwater environment, they will produce a series of persistent pollution and are not easy to be removed. Therefore, it is becoming more and more important to remediate the groundwater environment polluted by heavy metals, and the research on its re...

Problems solved by technology

Domestic research on tea saponin started relatively late, and its application in the environmental protection industry is still in its infancy. Recently, there have been related studies on the use of tea saponin to repair heavy metal pollution in the environment, such as tea saponin on sewage irrigation soil, metal smelters, etc. Remediation of heavy metals in single soil such as surrounding soil, but there are few studies on using it to control heavy metal pollutants in water
