Description

technical field

[0001] The invention relates to the field of environmental engineering, in particular to a device for underground sewage percolation treatment and a use method thereof. Background technique

[0002] The sewage underground infiltration treatment method usually refers to the controlled dosing of sewage into the soil after pretreatment, the sewage diffuses under the action of gravity and soil capillary force, and in the process of migration through physical interception, physical and chemical adsorption , chemical precipitation, microbial degradation, animal and plant action and other factors are purified. The underground infiltration treatment method has the advantages of good water quality, low construction and operation costs, simple management, no damage to the landscape, no odor, no sludge, and effective removal of nitrogen and phosphorus. Therefore, it has become increasingly important at home and abroad. sewage treatment methods.
