FIG. 1 is a schematic structural view of the present invention;
in the figure: a water collection tank 1; a water collecting pipeline 2; a first filtration tank 3; a rainwater pipeline 4; a road surface catch basin 5; a second filtration tank 6; a purified rainwater storage tank 7; a water pressure automatic control pump 8; a municipal water supply line 9; a check valve 10; a drinking water supply line 11; a user water inlet line 12; a water works 13; a branch line 14; a water supply line 15.
Detailed Description
The invention is further described below with reference to the accompanying drawings and specific embodiments.
An urban rainwater collecting and utilizing system comprises a roof rainwater collecting system and a ground rainwater collecting system. Roof rainwater collection system comprises water catch bowl 1, first filtering ponds 3 and rainwater pipeline 4, and water catch bowl 1 is connected through catchment pipeline 2 with first filtering ponds 3, and first filtering ponds 3 are connected with rainwater pipeline 4 through catchment pipeline 2. Because silt content is less relatively in the rainwater on roof, the rainwater is difficult for being polluted, it is more clear, consequently only need with the large granule in the rainwater on the roof filter in first filtering ponds 3, deposit can, then in introducing rainwater pipeline 4 with the rainwater after filtering again, flow into water works 13 as the raw water with the water in rainwater pipeline 4, mix with the raw water in water works 13 and handle the back as the drinking water, supply the user to use through drinking water supply pipeline 11.
The ground rainwater collecting system consists of a road rainwater well 5, a second filtering tank 6 and a purified rainwater storage tank 7. The road surface rainwater well 5 is connected with the second filtering pond 6 through the water collecting pipeline 2, the second filtering pond 6 is connected with the purified rainwater storage pond 7 through the water collecting pipeline 2, and the purified rainwater storage pond 7 is communicated with the user water inlet pipeline 12 through the water supply pipeline 15 for the daily non-drinking functional water of a user. It is provided with water pressure automatic control pump 8 in 7 to purify rainwater storage pond, purifies rainwater storage pond 7 and squeezes into water supply pipe 15 through the rainwater after its water pressure automatic control pump 8 will purify in, through water supply pipe 15 with the rainwater after purifying along user's inlet channel 12 get into user's pipeline in, satisfy that the user is daily waters non-drinking function water such as flower, closestool bath, dust fall.
In order to prevent the occurrence of the condition that the daily non-drinking functional water demand of the user is insufficient due to insufficient water in the purified rainwater storage tank 7, a branch pipeline 14 is led to the municipal water supply pipeline 9 to be communicated with the water supply pipeline 15, and the normal water use of the user is ensured under the condition that the water in the purified rainwater storage tank 7 is insufficient. In order to prevent water of the water supply line 15 from flowing back into the purified rainwater storage tank 7 and the municipal water supply line 9, one check valve 10 is installed on the branch line 14 and the water supply line 15, respectively, and the check valve 10 on the water supply line 15 is located before the connection end of the branch line 14 and the water supply line 15, so as to ensure that municipal water supplied into the water supply line 15 does not flow back into the purified rainwater storage tank 7.
When the embodiment is applied, the pumping pressure of the water pressure automatic control pump 8 in the purified rainwater storage tank 7 is slightly larger than the municipal water supply pressure.
The rainwater collecting system can effectively collect rainwater on the roof and the ground, has low purification cost, is simple and convenient to install, can be conveniently used for a municipal centralized rainwater treatment system, reduces the drainage pressure of urban water, reduces the urban waterlogging phenomenon, can effectively relieve the urban water pressure, and realizes rainwater collection and recycling.
The above are only specific embodiments of the present invention, but the protection of the present invention is not limited thereto, and all equivalent changes or substitutions of technical features to the technical features of the present invention that can be made by those skilled in the art are included in the protection scope of the present invention.
