3) The results showed that the content of copper ions in the two groups was not high at the early stage of the experiment, because some of the copper ions in the solution were absorbed by the caloricus's metabolic capacity, but the contents of copper ions in the two groups were not high, Three weeks, the content of copper ions in the non-brick group increased sharply, indicating that the absorption of copper ions in the iris at this time has been overloaded and can not absorb copper ions in a large amount, which leads to the high content of copper ions in the last few weeks No less, Iris also situation deteriorating。 And the experimental group of building waste brick as wetland filling matrix can still grow normally。

In summary, the construction waste brick is beneficial to the growth of calamus, the relative content of chlorophyll and the photosynthetic characteristics of calamus can promote the purification ability of calamus。 Therefore, the construction of waste bricks as a wetland to fill the substrate, not only reduce the improper handling caused by environmental pollution, while avoiding waste of resources, give full play to its value。

Key words: building waste brick, calamus, copper - containing wastewater, physiological characteristics
