The concentration of object.
(5) collection of soil diffusate
In the period Mo of one rainfall event, split transparent column cylinder and be sampled, sampling interval 10-12cm.During sampling, use
Scraper that distilled water is cleaned scrapes a certain amount of soil sample, and (amount of soil sample is determined by the pollutant kind that needs to detect and its content
It is fixed), and be fitted into prior ready transparent bag, marked soil layer height and carry out the detection of pollutant as early as possible.
(6) in the soil body pollutant load measure
The soil body sample being collected into is immersed in distilled water to the leachate for the body that fetches earth, and the leachate of each layer soil body is divided into
Several groups, the content of each pollutant in leachate is measured by chemical reagent detection method.It records each in different soil height
The content of pollutant analyzes the time space distribution of pollutant.
Example one：The time space distribution oozed under certain city initial rainwater pollutant
To build sponge city, the recycling of rainwater resource is realized, certain city has probed into initial rainwater pollutant and existed
Time space distribution in the soil body of sunk type greenery patches.By analyzing every piece of sunk type greenery patches of this area's rainfall data over the years and combination
Catchment area, the head for choosing 200mm as whole day rainfall carry out test simulation, 10min and preceding 40min before mainly determining
Under ooze situation and pollutant time space distribution, pass through analysis, it is assumed that in two hours rainfall complete, every ten minutes sunk types
The charge for remittance head in greenery patches is 16.67mm.Mainly determine COD (COD), TP (total phosphorus), TN (total nitrogen), N-N (ammonia nitrogen)
Wait the content of pollutants.The soil sample chosen in sunk type greenery patches is filled in cylindrical drum, and is laid with one layer of turf on model top.
10min rainfalls institute water requirement is calculated, model top is poured into, maximum permeated height and pollutant load is measured after 10min；Together
When calculate water consumption needed for 40min rainfalls, repeat aforesaid operations, maximum permeated height and pollutant load measured after 40min, is obtained
To initial rainfall stage and the time space distribution for washing away stage pollutant.The time and space idea that pollutant is distributed in the soil body is under
The design in heavy greenery patches provides greatly engineering reference.
Example two：The spatial and temporal distributions research oozed under certain sponge engineering pilot initial rainwater pollutant
Urban waterlogging is being eliminated in sponge city, and plays significant role in terms of making rainwater infiltration with recharge groundwater.To keep away
Exempt from initial rainwater to pollute water quality in the process for forming rainwash remittance underground water, initial rainwater at this need to be estimated in advance
Time space distribution of the middle pollutant in infitration process.According to the survey, initial rainwater pollutant is mainly derived from root at this
Entrained pollutant in the runoff that pavement runoff and roof collect, the type of pollutant mainly include SS (suspended matter), COD
(COD), TP (total phosphorus), TN (total nitrogen), N-N (ammonia nitrogen) etc.., choose head progress of the 200mm as whole day rainfall
Test simulation oozes situation and pollutant time space distribution, it is assumed that small two before mainly determining under 10min and preceding 40min
When interior rainfall complete, the charge for remittance head in every ten minutes sunk type greenery patchess is 20mm.The soil sample chosen in cavernous body fills model, counts
10min rainfalls institute water requirement is calculated, model top is poured into, maximum permeated height and pollutant load is measured after 10min；Simultaneously
Water consumption needed for 40min rainfalls is calculated, aforesaid operations is repeated, maximum permeated height and pollutant load is measured after 40min, is obtained
Initial rainfall stage and the time space distribution for washing away stage pollutant.The experiment obtains final pollutant time space distribution
There is great reference value to the depth of fill design of cavernous body.
The foregoing is merely the preferred embodiments of the application, are not limited to the application, for the skill of this field
For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair
Change, equivalent replacement, improvement etc., should be included within the protection domain of the application.
