Embodiment 1
[0038] according to Figure 1 to Figure 7 As shown, a method for improving rural domestic sewage discharge outlets includes the following steps:
[0039] First, excavate the earthwork on the river bank above the sewage discharge outlet of the river, and the excavation depth is 1 to 3 meters lower than the bottom of the sewage discharge outlet, forming the area of the ecological adjustment pool 3;
[0040] Second, cut off the original sewage outlet, form a new outlet, and build up successively at the new outlet, the collection pool 42 and the pretreatment pool 43
[0041] Third, construct the 8 parts of the anti-seepage layer below the surface flow slope 6, and the specific method for constructing the 8 parts of the anti-seepage layer below the surface flow slope 6 is to drill oblique holes at the bottom of the excavated earthwork, and high-pressure grouting in the holes , forming an anti-leakage layer 8;
[0042] Fourth, use the pouring method to construct the 8 parts of t...

Abstract
The invention relates to the field of rural river water pollution treatment, in particular to a reconstruction method of a rural domestic wastewater discharge port. The reconstruction method includes the following steps that 1, earth of a riverbank above the rural wastewater discharge port is dug; 2, the former wastewater discharge port is cut off, a new wastewater discharge port is formed, and a collection pond and a pre-treatment pond are sequentially constructed at the new wastewater discharge port; 3, a seepage prevention layer below a surface-flow slope is constructed; 4, a seepage prevention layer below an underflow slope is constructed to be connected with the seepage prevention layer below the surface-flow slope, earth filing is conducted 50 cm above the highest river water line, and the underflow slope is formed; 5, ecological building blocks are laid on the surface of the surface-flow slope; 6, concrete top covers are used for covering the collection pond and the pre-treatment pond, and a land platform is formed; 7, plants are planted on the surface-flow slope and the underflow slope, the surface-flow slope and the underflow slope form a bank protection slope together, and a water collection wall and a water outlet pipe are arranged between the surface-flow slope and the underflow slope; 8, the end, close to water, of an ecological adjustment pond is provided with a floating wall.
Description
technical field [0001] The invention relates to the field of water pollution control of rural water channels, in particular to a method for transforming rural domestic sewage discharge outlets. Background technique [0002] With the rapid development of the countryside and the rapid improvement of the living standards of the vast number of rural people, as well as the development of rural livestock and poultry breeding, aquaculture and agricultural by-product processing and other industries, the discharge of rural domestic sewage continues to increase, seriously destroying the ecological balance of the countryside. Rural domestic sewage mainly comes from feces and its flushing water, bathing sewage and kitchen sewage, and sewage produced in the process of scattered farming in rural areas. The water quality of rural domestic sewage is characterized by high N and P content, strong biochemical properties, and less toxic and harmful substances such as heavy metals. In terms of d...
