Description of drawings
Fig. 1 is a lawn of the present invention irrigation system of sewage structural representation.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1,1 is grid, and 2 is sewage water inlet pipe, and 3 is underground sand filtering ponds, and 4 is the sand layer, and 5 is the gravelstone sublayer, stone diameter 0.5cm, and 6 is big stone layer, stone diameter 2cm, 7 is the tube connector of sand filtering ponds and sedimentation basin; 8 is valve, and 9 is the subsurface irrigation main, and 10 is the joint of subsurface irrigation main and arm, 11 is the control room, and 12 is manometer, and 13 is flowmeter, 14 is filter, and 15 is water pump, and 16 is sedimentation basin, 17 are the mixed pool wall of brick, 18 is vertical water-supply-pipe, and 19 are outlet, and 20 for being positioned at the partition of sedimentation basin 16, it is divided into two parts with sedimentation basin 16, i.e. intake pool that communicates with underground sand filtering ponds 3 and the discharge bay that communicates with water pump 15.
Found out that by Fig. 1 whole lawn irrigation system of sewage is made up of sewage disposal system and irrigation system of sewage two large divisions, this two large divisions is integrated structure design.In the present embodiment, sewage disposal system is made up of sand filtering ponds 3 and sedimentation basin 16, and sedimentation basin 16 double as cisterns load three-layer filter in the sand filtering ponds 3, and lower floor is big stone, and the middle level is a handstone, and the upper strata is a sand.Irrigation system of sewage is made up of head pivot (comprising water pump, filter, flowmeter, manometer etc.), subsurface irrigation main 9, arm, hollow billet and connector thereof.And be arranged on control room 11 on the sedimentation basin 16, and then be to have utilized the space dexterously satisfying on the basis of technological process (sedimentation basin is lower than filtering ponds), also the maintenance for system provides convenience.
