Simulation device and implementation method for road ecological infiltration system to treat runoff pollution

Abstract

A simulation device for treating runoff pollution by a road ecological infiltration system and its realization method relate to a simulation device for a percolation system. It includes a box body, which is characterized in that the top of the box body is an open structure, and there are several layers of horizontal water-permeable partitions and several longitudinal sealing partitions in the box body; the left or right side of the box body is an open structure, and there is a The airtight door can be opened and closed, and the longitudinal sealing partition is set on the side with the airtight door; there is a nozzle on the top of the box, and two slopes facing each other at the bottom of the inner side of the box, and a water outlet at the intersection of the bottom of the two slopes . The present invention can control the elevation of the four corners of the box body, select a suitable number of horizontal water-permeable partitions and longitudinal sealing partitions according to needs, and fill the space composed of horizontal water-permeable partitions and longitudinal sealing partitions with the purification materials to be tested or purify For vegetation, the simulated runoff sewage is sprayed through the nozzle, and the simulated sewage passes through each layer of vegetation or materials. The slope and water outlet at the bottom of the box are convenient for the collection of water samples.

Description

technical field [0001] The invention relates to a simulation device of a percolation system, in particular to a simulation device of a road ecological percolation system capable of simulating filling filter materials and vegetation to treat polluted water and its realization. Background technique [0002] The ecological infiltration system is a rainstorm runoff treatment system composed of excavated ditches, backfill media and plants. In practical applications, it can be a long and thin ditch or a retention pond. It belongs to the low-impact development technology in the United States, that is, this measure is adopted at the source to absorb rainwater on the spot. Research at home and abroad has found that the ecological filter ditch is efficient and stable in removing TSS and heavy metals. [0003] At present, some progress has been made in the research work of using the ecological infiltration system to treat runoff pollution, but there is no systematic and integrated sim...

Problems solved by technology

[0003] At present, some progress has been made in the research work of using the ecological infiltration system to treat runoff pollution, but there is no systematic and integrated simulation device for the treatment of runoff pollution by the ecological infiltration system

This directly leads to the cumbersome process of traditional laboratory or open-air simulation tests, which increases manpower and material resources, and more or less leads to deviations in test results.
