It checks in the content of ammonia nitrogen on curve, and calculates after zeolite and concrete dynamic modulus cement concrete is added and gathers materials and concrete dynamic modulus cement
Concrete aggregate (being added without zeolite) is to the purification efficiency of ammonia nitrogen, as shown in Figure 3.
It calculates：Ammonia nitrogen (N, mg/L)=1000m/v；
In formula：The ammonia nitrogen amount (mg) that m-is checked in by standard curve；
V-volume of water sample (mL).
To sum up, as shown in Figure 1, concrete dynamic modulus cement concrete gather materials and (be added without zeolite) to the clean-up effect of suspended matter compared with
Good, purification efficiency reaches 63.3%；After addition zeolite gathers materials with concrete dynamic modulus cement concrete, with concrete dynamic modulus cement concrete collection
Material (being added without zeolite) is compared, and zeolite and concrete dynamic modulus cement concrete is added and gathers materials the purification that can be further increased to suspended matter
Effect, i.e. purification efficiency reach 74.4%.
Concrete dynamic modulus cement concrete gathers materials and (is added without zeolite) to ammonia nitrogen almost without detergent power, and purification efficiency is extremely low,
Its value is 14.6%；After addition zeolite gathers materials with concrete dynamic modulus cement concrete, gathers materials with concrete dynamic modulus cement concrete and (be added without
Zeolite) it compares, zeolite and concrete dynamic modulus cement concrete is added and gathers materials the clean-up effect significantly improved to ammonia nitrogen, i.e. purification efficiency
It is 68.6%；Therefore, addition zeolite significantly improves concrete dynamic modulus cement concrete after gathering materials with concrete dynamic modulus cement concrete and gathers materials
The clean-up effect of (being added without zeolite) to ammonia nitrogen.
Concrete dynamic modulus cement concrete gathers materials and (is added without zeolite) to total phosphorus almost without detergent power, and purification efficiency is extremely low,
Its value is 14.4%；After addition zeolite gathers materials with concrete dynamic modulus cement concrete, gathers materials with concrete dynamic modulus cement concrete and (be added without
Zeolite) it compares, zeolite and concrete dynamic modulus cement concrete is added and gathers materials the clean-up effect significantly improved to total phosphorus, the boiling of water purification filtrate
Stone is fine to the clean-up effect of total phosphorus, and purification efficiency reaches 72.5%；Therefore, zeolite is added with concrete dynamic modulus cement concrete to gather materials
The clean-up effect that concrete dynamic modulus cement concrete gathers materials and (is added without zeolite) to total phosphorus can be significantly improved afterwards.
In short, compared with being added without water purification filtrate zeolite, water purification filtrate zeolite is added and gathers materials with concrete dynamic modulus cement concrete
Concrete dynamic modulus cement concrete can be improved afterwards to gather materials and (be added without zeolite) to the net of suspended matter, ammonia nitrogen pollutant and total phosphor contaminant
Change effect, especially has a very significant increase to the clean-up effect of ammonia nitrogen pollutant and total phosphor contaminant, can apply in nutrition
In the more road surface in for example neighbouring dining room in the more region of pollutant.Therefore, the purification method of the rainwater runoff pollution object can
Directly to effectively improve the clean-up effect of concrete dynamic modulus cement concrete, and the environment of different pollutants can be flexibly coped with, from
And the pollution problem for alleviating runoff sewage can be imitated, i.e., it is of great significance to the detergent power of different runoff pollution environment.
The above-mentioned description to embodiment is that this hair can be understood and used for the ease of those skilled in the art
It is bright.Those skilled in the art obviously readily can make various modifications to these embodiments, and described herein one
As principle be applied in other embodiment, without having to go through creative labor.Therefore, the present invention is not limited to the above embodiments.
Those skilled in the art's principle according to the present invention, not departing from improvement that scope of the invention is made and modification all should be at this
Within the protection domain of invention.
