Method for supplementing leacheate during on-line acidic precipitation monitoring

Abstract

The invention discloses a method for supplementing leacheate during on-line acidic precipitation monitoring. The method comprises the following steps of: recycling leacheate, wherein a leacheate outlet of a conductivity detector is connected with a recycling pipe and led to a suppressor, so that water can be supplemented into the suppressor, and sodion can be removed from the suppressor; and liquid containing water, sodion and carbanion enters a leacheate bottle for recycling; and supplementing the leacheate, wherein a concentration detector is arranged in the leacheate bottle and sends a proper concentration signal of the leacheate to a central control chamber; a deionized water tank is arranged near the leacheate bottle and connected with the leacheate through a counting pump; and the central control chamber controls the counting pump to be opened to directly pump water into the leacheate bottle until the concentration of the leacheate is stable, and the preset concentration range is reached, according to the change of the concentration of the leacheate. According to the method, the leacheate can be effectively supplemented, and the stability of the concentration of the leacheate can be guaranteed according to the change of the concentration of the leacheate.

Description

technical field [0001] The invention specifically relates to a method for replenishing eluent for on-line monitoring of acid deposition, and belongs to the technical field of environmental monitoring. Background technique [0002] The supply and concentration control of the eluent (the main components are sodium carbonate and sodium bicarbonate) is the key technology to realize the on-line monitoring of acid deposition. At present, the replenishment of eluent and the concentration control in the process of use are mostly artificial replenishment and control, which not only has the problems of frequent replenishment and control, time-consuming, and laborious, but is especially important because acid rain often occurs due to insufficient replenishment and concentration control. The analysis accuracy is reduced, thus losing the purpose of real-time monitoring. At the same time, there is also a method of using a eluent generator to replenish the eluent, but this method not only...

AI Technical Summary

Problems solved by technology

At present, the replenishment of eluent and the concentration control in the process of use are mostly artificial replenishment and control, which not only has the problems of frequent replenishment and control, time-consuming, and labor-intensive problems, but is especially important because acid rain often occurs due to insufficient replenishment and concentration control. The analysis accuracy is reduced, thus losing the purpose of real-time monitoring

At the same time, there is also a method of using a eluent generator to replenish, but this method not only has the problems of high equipment cost and high operating cost, but also the concentration is difficult to control, so it cannot be used or the effect is poor in remote places such as suburbs and deep mountains.
