In addition, nature of glass foaming body 40 has a large amount of bubbles, so as long as by nature of glass foaming body 40, water will be cleaned, final, water purification can be stored in the 1st storage portion 12.Therefore, this storage water has just become the water that can be used for irrigating vegetation fully or clean vehicle, garden etc.And nature of glass foaming body 40 is alkaline, and therefore, the water that passes through can become the pH value at the alkaline water more than 9.So nature of glass foaming body not only has the effect that prevents the rainwater corrosion, also has the effect that suppresses recent breedings such as Escherichia coli.Under this effect, need not rainwater accumulator tank 100 is safeguarded, can make its function long term maintenance.
And, in discarded,, therefore, can not produce trade waste directly as soil treating because nature of glass foaming body 40 is recycling products of glass.
In addition, need not with concrete etc. fixingly around the storage portion 10, when carrying out the construction of rainwater accumulator tank 100, under most of situation, only can finish, almost need not handwork with jumbo, therefore, but reduction of erection time, labor savings simultaneously.In addition, this rainwater accumulator tank need not to construct the basis, therefore, and further reduction of erection time.
In addition, if plantation such as flower bed vegetation is set on rainwater accumulator tank 100, the water of preserving in the nature of glass foaming body 40 of the 2nd storage portion 13 can suitably give the backfill moisture, therefore can reduce the trouble of sprinkling water.

Aspect turbidity, detected the water of obvious muddiness in the comparative example 1, especially after 3 months.On the other hand, in embodiment 1, not visually substantially see muddiness.This is that nature of glass foaming body has been brought into play catharsis to a great extent.
Aspect the pH value, the pH value of comparative example 1 is in and is a bit larger tham 8 degree between 8.12～8.64.With respect to this, embodiment 1 is in any time after 3 days, after about 1 month, after about 2 months, and the pH value is all greater than 9, and this expression embodiment 1 has alkalized.
Aspect bright lattice rel index, the numerical value of comparative example 1 after 3 days is-0.96, and numerical value is lower, but after 1 month, after 2 months, the numerical value that demonstrates is 0.04, settles out.On the other hand, the bright lattice rel index after 3 days of embodiment 1, after 1 month, after 2 months is between 0.79～1.02, and numerical value is all than higher.But so-called bright lattice rel index is considered to be the corrosivity of water and the formation standard of calcium carbonate overlay film, can calculate by following formula 1.Bright lattice rel exponential number is big more, and calcium carbonate is easy more separates out, and its corrosion resistance is just high more.According to numerous examples, if bright lattice rel index more than-1.0, its anticorrosion effect will be worth the expectation.
(formula 1)
Bright lattice rel index=pH-pHs
But, pHs=8.313-log (Ca
2+)-log (A)+s
PH: the actual pH of water
PHs: the pH value when being in equilibrium state
Log (Ca
2+): the logarithm of calcium ion concentration
Log (A): the logarithm of total alkalinity
S: corrected value
According to above formula, as can be known, want to improve corrosion resistance (improving bright lattice rel index), will improve basicity, or the concentration that improves calcium ion be reached by improving the pH value.In experiment, the corrosion resistance effect of embodiment and comparative example all is worth expectation, but its reason is different.In an embodiment, the reason that is improved of bright lattice rel index is its basicity height.And in an embodiment, basicity is tall and big to have benefited from nature of glass foaming body more, and therefore, it just can keep stronger corrosion resistance.Generally speaking, in order to keep the basicity of water, can drop into lime in accumulator tank, still, this rainwater accumulator tank does not have this necessity.On the other hand, comparative example shows more weak corrosion resistance, can think that this is because its calcium ion is more.Calcium ion is supplied with by soil.According to this relatively, we can think that in an embodiment, calcium ion is in precipitation state, and with respect to this, in comparative example, ion is in free state.But, measure basicity, needs use pH value is 4.3 acid, detects until the acid consumption that the pH value is neutralized to 7.0.
About the coli-group number, find that behind comparative example after 3 days, after about 1 month, after about 2 months, Escherichia coli increase gradually, are respectively 0,55,78.With respect to this, through confirming that in an embodiment, colibacillary quantity only rises to 2n/ml from 1n/ml, colibacillary level is very low.In an embodiment, why a lot of colibacillary group number is, be because nature of glass foaming body with the water quality alkalization.Bacterium classes such as Escherichia coli have the tendency of detesting the highly basic state, if add and do experimental conditions in the fields, the Escherichia coli among the embodiment will can not breed.
