Cleaning agent applicable to descaling of landfill leachate evaporator and preparation method and application thereof

Abstract

The invention provides a cleaning agent applicable to descaling of a landfill leachate evaporator and a preparation method and application thereof, and the cleaning agent applicable to descaling of the landfill leachate evaporator is characterized by comprising the following components by weight: 80-90 parts of water; 5-8 parts of ethylenediamine tetraacetic acid disodium salt; 2-6 parts of sodiumcarbonate; 4-6 parts of sodium hydroxide; 0.00018-0.0009 parts of ethylenediamine tetramethylenephosphonic acid; 0.0003-0.0004 parts of sodium hydroxide; and 0.00045-0.002 parts of hydrolytic polymaleic anhydride. The invention further discloses a preparation method and application of the cleaning agent applicable to descaling of the landfill leachate evaporator. The cleaning agent can effectively soften and remove dirt generated by the landfill leachate evaporator in the landfill leachate treatment process, basically has no corrosion loss and side reaction to evaporation equipment, is simplein formula and good in descaling effect, and solves the problem of scaling of the landfill leachate treatment evaporator.

Description

technical field [0001] The invention relates to the cleaning agent technology for descaling, in particular to a cleaning agent suitable for descaling evaporators of landfill leachate, its preparation method and application. Background technique [0002] Leachate is a kind of high-concentration wastewater with serious pollution and complex components. Its composition and water volume vary greatly with seasons and landfill time. As the country pays more and more attention to environmental protection, the water quality of landfill leachate becomes more and more complicated. In recent years, the Environmental Protection Bureau has successively promulgated various regulations and standards for sewage discharge control. The ammonia nitrogen in the landfill leachate is high, the BOD is low, the COD is high, and there are fine suspended particles. During the evaporation process inside the evaporator, scales that are difficult to dissolve will condense on the surface of the heat exch...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to propose a cleaning agent suitable for descaling of landfill leachate evaporators in view of the problem that the heat exchange rate of the heat exchange tubes of the landfill leachate evaporator after fouling will drop significantly and seriously affect the evaporation efficiency , the cleaning agent can effectively soften and remove the dirt generated by the landfill leachate evaporator in the process of landfill leachate treatment, and basically has no corrosion loss to the evaporation equipment, no side reactions, simple formula, good descaling effect, and solves the problem of garbage Leachate Treatment Evaporator Fouling Problem
