Thermoactinomyces-vulgaris-containing desilting agent and application thereof in salt drainage concealed pipes

Abstract

The invention provides a Thermoactinomyces-vulgaris-containing desilting agent which comprises a biocatalyst, a nonionic surfactant, an aloe extracting solution, a purslane extracting solution, a Herba Centellae extracting solution, a bioenzyme activator, borax, shikimic acid, humic acid, a vitamin complex, a substrate, a porous sodium-type activated zeolite powder carrier, halophile, Thermoactinomyces vulgaris and a crosslinking agent. The invention also provides application of the Thermoactinomyces-vulgaris-containing desilting agent in salt drainage concealed pipes. The desilting agent lowers the salt content of water in the salt drainage concealed pipe, and the salt content of water at the outlet of the salt drainage concealed pipe is lowered to 0.49-0.61%. The desilting agent lowers the plugged hole percentage of the salt drainage concealed pipe, and the plugged hole percentage of water in the salt drainage concealed pipe is lowered to 11-12%. The desilting agent enhances the saline-alkali soil silt treatment speed, and the time for treating 8cm-thick saline-alkali soil silt is 6-7.0 days. The desilting agent has favorable desilting effect; and one year after desilting, the water transparency is up to 10-12cm, whereas the transparency of the control group is 5cm.

Description

technical field [0001] The present invention relates to a dredging agent and its application in salt-discharging underground pipes, in particular to a dredging agent containing ordinary high-temperature actinomycetes and its application in salt-discharging concealed pipes, belonging to saline-alkali underground pipe salt-discharging technology field. Background technique [0002] Underground pipe salt drainage technology is to lay a pipeline with pores at a certain depth underground (above or below the groundwater level), and the water that flows into the pipeline after irrigation or rainfall, or directly flows into the groundwater in the pipeline, and is discharged through the pipeline land, take away the salt, and play the purpose of improving saline-alkali land. [0003] After the alkali discharge pipe has been used for a period of time, finer sediment will accumulate in the pipe, referred to as fine mud. As an important part of water body, fine mud is a mixture of clay,...

AI Technical Summary

Problems solved by technology

[0005] (1) Existing desilting agents cannot reduce the salt content of water in the salt drainage pipe in saline-alkali land;

[0006] (2) Existing dredging agents have a high plugging rate of salt drainage pipes in saline-alkali land;

[0007] (3) The existing dredging agent is slow in treating sludge, especially in saline-alkali land;

[0008] (4) The existing dredging agent has poor dredging effect, and the degree of increase in transparency and dissolved oxygen (DO) after dredging is limited
