Abstract

The invention provides a desilting agent containing denitrifying salt-enriching bacteria, which includes biocatalyst, nonionic surfactant, cactus extract, licorice extract, dandelion extract, biological enzyme active agent, potassium nitrohumate, mustard acid, fulvic acid, multivitamin, substrate, porous sodium-type activated zeolite powder carrier, halophilic bacteria, denitrifying salt-rich bacteria, cross-linking agent; the present invention also provides a desilting agent containing denitrifying salt-rich bacteria in Application in the salt-discharging dark pipe; the dredging agent of the present invention reduces the five-day biochemical oxygen demand (BOD) of water in the salt-discharging dark pipe 5 ), the five-day biochemical oxygen demand after 100-fold dilution of the water at the outlet of the salt discharge concealed pipe is 8.5‑10.7 mg / L; the content of suspended solids in the salt discharge concealed pipe water has been reduced, and the content of suspended solids in the salt discharge concealed pipe water is 7.7‑ 10.1%; the dredging effect is good. After one year of dredging, the removal rate of total phosphorus in water reaches 85.7-90.1%, and the content of small molecule soluble carbon in water reaches 55.1-57.3%, compared with 30.0% in the control group.

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 denitrifying salt-enriching bacteria 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, se...
