Simulation device for treating runoff pollution of road ecological percolation system and realization method of simulation device

Abstract

The invention provides a simulation device for treating runoff pollution of a road ecological percolation system and a realization method of the simulation device, and relates to the simulation device of the percolation system. The simulation device comprises a box body, and is characterized in that the top of a box body is in an opening type structure; the box body is internally provided with a plurality of horizontal permeable separation plates and a plurality of vertical sealed separation plates; the left side or the right side of the box body is in an opening type structure, and is provided with a sealing door capable of being opened and closed; the vertical sealed separation plates are arranged on one side of the sealing door; a nozzle is arranged above the box body; and the bottom of the inner side of the box body is provided with two inclined slopes which are arranged oppositely, and a water outlet is formed in the crossed part of the slope bottoms of the two inclined slopes. The simulation device can be used for controlling the elevations of four corners of the box body; a proper number of horizontal permeable separation plates and the vertical sealed separation plates are selected, and spaces formed by the horizontal permeable separation plates and the vertical sealed separation plates are filled with purification materials or purification vegetation to be detected; runoff sewage is simulated by spraying of the nozzle, a condition that the sewage passes through each layer of vegetation or materials is simulated; and the inclined slopes and the water outlet are arranged at the bottom of the box body so that a water sample is convenient to collect.

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.
