Problems solved by technology
At present, the experimental devices for studying the migration and transformation process of pollutants are mostly limited to laboratory soil column experiments.
The soil column device is basically composed of a thin and tall circular box, water distribution pipes, and water collection pipes. Its shape and specifications are too small, and its height-to-diameter ratio is too large, which is not enough to analyze the real environment inside the infiltration system, and there is a large degree of side walls. Effect, affecting the analysis of water flow characteristics of the infiltration system

Embodiment
[0020] See Figure 1 to Figure 6 , a device for testing the migration and transformation of pollutants in a percolation system, consisting of an upper box 1 (length, width, and height are 100cm×60cm×70cm), a middle box 2 (length, width, and height are 100cm×60cm× 60cm) and the lower box 3 (the length, width and height are respectively 100cm×60cm×70cm) to form a large box. The bottom of the lower box 3 is closed, the lower end is located on the base 5, the lower end of the middle box 2 is connected with the upper end of the lower box 3 through the flange 4, and the lower end of the upper box 1 is connected with the upper end of the middle box 2 through the flange 4. Lower box body 3 sides are provided with water outlet 9 near the bottom, and lower box body 3 interior is installed water collection pipe 10 at water outlet 9 places, and interface is sealed with waterproof sealant, and this water collection pipe 10 bottoms evenly distributes several fine holes. There are five rese...

Abstract
The invention discloses a device for analyzing and testing pollutant migration and transformation of a filtration system, and relates to a device for filtering and purifying sewage by means of matrixes. The device comprises a box, a base, samplers, a water distribution pipe, water collection pipes, a water dispersion pipe, impermeable water vessels, a ceramic permeable connector and a control valve; the upper end of the box is provided with an opening, the lower end of the box is closed and located on the base, the box is divided into an upper box body, a middle box body and a lower box body, and the middles of the upper box body, the middle box body and the lower box body are fixedly connected through flanges; the three side faces of the box are provided with multiple reserved openings, and the reserved openings are closed by rubber plugs or provided with sensors and the samplers; the water distribution pipe is arranged in the box and vertically connected to the middle of the water dispersion pipe, the pipe wall of the water dispersion pipe is evenly provided with multiple fine holes, and the impermeable water vessels are arranged below the water dispersion pipe and laid on the matrixes filled in the box. According to the device, the pollutant migration and transformation process can be analyzed by continuously monitoring the soil water potential and water content in the filtration system.
Description
technical field [0001] The invention relates to a device for purifying sewage by matrix percolation, in particular to a device for analyzing and testing the migration and conversion of pollutants in a percolation system. Background technique [0002] Sewage soil infiltration treatment process is based on ecological principles and integrates anaerobic and aerobic treatment processes to form a small-scale sewage land treatment technology. The basic principle is: after the sewage is treated by precipitation and hydrolysis in the pretreatment process, it is distributed into the water distribution pipe, and the sewage flowing out of the water distribution pipe infiltrates evenly to the aerobic filter layer, and then the combined action of soil water suction and gravity Do the spreading exercise. Under the comprehensive action of the soil-microbe-plant system, pollutants are removed through physical and chemical adsorption, chemical precipitation, microbial degradation, etc., the...
