The synergistic effect of the structure, formula and modified polyaluminium chloride in the implementation 5 can be the main reason of the technical scheme which is the same as the technical scheme in the application and can obviously improve the water purification capacity.
The use method of the novel irrigation device for ecological restoration of the small mine in the karst rocky mountain area comprises the following steps:
firstly, collecting rainwater by using a water collecting tank 1, purifying the collected rainwater by using a water purifying layer 2 arranged in the water collecting tank 1, enabling the purified rainwater to flow into a filter tank 3, filtering by using a filter element 4 in the filter tank 3, and finally flowing into a water storage tank 5 for storage, thereby finishing the storage of the rainwater; when needs sprayed vegetation, only need spray the vegetation through raceway 6 with the water in the catch basin 5 by shower head 7 under the effect of water pump 8 on, solved the complicated not convenient for of mine environment and carried the problem that the water was irrigated to the vegetation from the external world.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made thereto by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should be considered as falling within the scope of the present invention.
