Application of scale inhibitor with good antibacterial effect in salt discharge underground pipe

Abstract

The invention relates to a scale inhibitor with good antibacterial effect, and the scale inhibitor comprises the following components by weight: 33-37 parts of ethylenediamine tetramethylene phosphonic acid, 18-22 parts of amino trimethylene phosphonic acid pentasodium, 9-13 parts of poly aspartic acid, 8-12 parts of citric acid, 10-14 parts of hydroxyethylidene-1,1-diphosphonic acid, 3-7 parts of sodium polyacrylate, 10-14 parts of dithiocyano-methane, 9-13 parts of dioctadecyl dimethyl ammonium chloride, 3-7 parts of butylated hydroxytoluene, 3-7 parts of dioctyl sodium sulfosuccinate, 3-7 parts of polyacrylamide, 1-5 parts of dandelion extract, 1-5 parts of lemon extract and 56-60 parts of water, the scale inhibitor has good inhibitory effect on bacteria breeding in a salt discharge underground pipe, has good scale inhibition effect on inorganic salt precipitation in the salt discharge underground pipe, is stable in property and long in storage period, and may not cause corrosion of the wall of the salt discharge underground pipe.

Description

technical field [0001] The present invention relates to a scale inhibitor with good bacteriostasis effect, in particular to the application of a scale inhibitor with good bacteriostasis effect in a salt discharge underground pipe, belonging to the technical field of salt discharge in a saline-alkali underground pipe. Background technique [0002] Underground pipe salt drainage technology is to lay a pipe with pores at a certain depth underground (above or below the groundwater level), and the water that will flow into the pipe after irrigation or rainfall, or directly flow into the groundwater in the pipe, and discharge the land through the pipe , take away the salt, and play the purpose of improving saline-alkali land. The effect of underground pipe salt drainage technology on improving saline-alkali land has been proved. Underground pipe salt drainage follows the water and salt migration law of "salt comes with water, salt goes with water", and the water that has fully di...

AI Technical Summary

Problems solved by technology

[0005] (1) It has no inhibitory effect on the bacteria that grow in the salt discharge concealed pipe, which reduces the service life of the concealed pipe;

[0006] (2) The scale inhibition effect on insoluble inorganic salts in saline-alkali water is not obvious, and it is easy to cause blockage of the salt discharge pipe;

[0007] (3) Antiscalants are unstable in nature, short in storage time and poor in dispersibility;

[0008] (4) The scale inhibition efficiency is low, and the dosage is large. When it is discharged to the external environment, it is easy to cause environmental pollution and increase the cost of subsequent treatment;

[0009] (5) It is easy to cause corrosion of the pipe wall of the salt drainage pipe
