Abstract

The invention provides a desilting agent containing Bacillus subtillis. The desilting agent comprises a biocatalyst, a nonionic surfactant, dandelion extract, shaddock peel extract, bladder-wrack extract, a bio-enzyme active agent, stannous chloride, sorbic acid, acetic acid, composite vitamin, a matrix, a porous sodium type activated zeolite powder carrier, halophilic bacteria, Bacillus subtillis and a cross-linking agent. The invention also provides application of the desilting agent containing Bacillus subtillis to a salt-removing subdrainage pipe. The desilting agent improves the chroma removal rate of water at the outlet of the salt-removing subdrainage pipe, wherein the chroma removal rate is 86 to 89%; the desilting agent reduces the turbidity of water at the outlet of the salt-removing subdrainage pipe, wherein the turbidity of water at the outlet of the salt-removing subdrainage pipe is reduced to 4.5 to 5.1 mg / L; the desilting agent has good desilting effect and reduces chemical oxygen demand of desilted water; and the desilting agent improves the removal rate of ammonia-nitrogen in water, and in one year after desilting, the removal rate of ammonia-nitrogen in water is 54.3 to 60.8%.

Description

technical field [0001] The invention relates to a dredging agent and its application in salt-discharging concealed pipes, in particular to a dredging agent containing Bacillus subtilis and its application in salt-discharging concealed pipes, belonging to the technical field of saline-alkali underground pipe salt-discharging . 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, sediment, organic matter...
