Abstract

The invention relates to a preparation method of a sewage soil infiltration device, which comprises the following steps that: a plexiglass tube of which one end is closed and the other end is welded with a flange is taken, and a small sampling hole is drilled at the center of a circle of a closed end surface; a plexiglass tube of which both ends are welded with flanges is taken; a plexiglass tube of which one end is provided with an opening and the other end is welded with a flange is taken; a matrix is evenly filled in the three plexiglass tubes, and the flange end surfaces of the three plexiglass tubes are connected by bolts; and the sewage is continuously injected into the plexiglass tubes, and is sampled from the small sampling hole, and then the water outlet quality is analyzed and the water outlet quality is monitored. In the preparation method of the sewage soil infiltration device, the problems that the matrix is unevenly filled, a matrix layer collapses and the water flow is short-circuited in the traditional soil column simulation soil percolation process, can be solved, and the treatment effect of the sewage is improved.

Description

technical field [0001] The invention relates to a method for purifying sewage by using soil infiltration treatment technology, in particular to a method for preparing a sewage soil infiltration device. Background technique [0002] Soil infiltration is a sewage ecological treatment technology formed by combining anaerobic and aerobic processes. The basic principle is: the sewage is distributed into the distribution pipe after being treated by sedimentation and hydrolysis in the pretreatment process. The sewage flows out evenly from the diffuser pipe, and then spreads under the joint action of soil capillary force and gravity, and fully contacts the soil. Through the joint action of the soil-microbe-plant system, the pollutants in the water are physically separated, chemically adsorbed and biologically separated. Degradation, clean water is collected through the water collection pipe. Soil column experiment is an important method for the study of sewage soil infiltration pr...
