Problems solved by technology

However, due to the scattered sources of domestic pollution in rural areas of our country, it is not easy to concentrate, the awareness of environmental protection of village and town residents is poor, and the level of economic development is not high, most rural areas still have not adopted any domestic sewage collection and treatment measures, and domestic sewage in villages and towns still affects the water environment. An important source of pollution of quality
Therefore, to find a rural sewage collection and treatment method that uses the original riverbanks of villages and towns as the domestic sewage treatment carrier, with good treatment effects, simple management and maintenance, low cost, and low energy consumption, will help solve the problem of difficult collection and treatment of domestic sewage in villages and towns in my country.

Embodiment 1

[0031] Riverside width B=4-4.5m, along the direction of water flow, the river section is divided into in-situ biological barrier purification ditch section 1 with length L1=140m, concrete overflow weir 2 with width L2=0.2m, and concrete overflow weir with length L3=18m Intermittent in-situ aeration tank section 3, surface flow constructed wetland system section 4 with length L4=40m, geotextile overflow weir 5 with width L5=0.15m. Plant revetment vegetation such as orchid Panax notoginseng and Zailihua and other landscape trees such as Photinia fruticosa, Lagerstroemia crape myrtle, and weeping willow on both banks of the river to construct ecological slope protection6. After entering the river bank 7 through the ecological slope protection 6, the sewage flows through the above-mentioned treatment areas in sequence, and finally overflows through the geotextile overflow weir 5 and is discharged into the downstream river bank. The bottom mud in the in-situ bio-barrier purificatio...

Abstract

The invention belongs to the technical field of rural domestic waste treatment, particularly relates to a method for in-situ ecological treatment of town domestic waste water by using river and creek converging. The method comprises the following steps that town rivers and creeks serve as carriers, an ecological protection slope is constructed along two sides of the rivers and creeks, an in-situ biology gate purification channel section in length of L1, a concrete downflow weir in the length of L2, a batch-type in-situ oxygenation tank section in the length of L3, a surface flow constructed wetlands system section in the length of L4 and a geotechnical cloth downflow weir in the length of L5 are sequentially constructed along a water flowing direction of the rivers and creeks to serve as wastewater treatment units. Domestic waste water is guided in the rivers and creeks for converging through the ecological protection slope on two sides of the in-situ biology gate purification channel section, and then the domestic waste water sequentially flow through the wastewater treatment units. The method uses original rivers and creeks in towns to serve as the carriers of the domestic waste treatment, uses a rural waste water collection and treatment mode which is good in treatment effect, simple in management and maintenance, low in cost of construction and low in energy consumption and has great significance on a problem that town domestic waste water is difficult to collect and treat in our country.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage treatment in rural areas, and in particular relates to a method for in-situ ecological treatment of domestic sewage in villages and towns by using riverside collection in water network areas. Background technique [0002] Residents of villages and towns in the water network area of ​​southern my country generally live scattered along the banks of the river, and domestic sewage is discharged into the nearby river bank or directly washes daily necessities in the river bank, resulting in water pollution of the river bank and serious eutrophication of the water body. The domestic sewage of villages and towns in the southern water network area has the following characteristics: (1) the amount of sewage is small, intermittently discharged, and the coefficient of variation is large; (2) the composition is complex, the content of organic matter is large, the content of nitrogen and phosphorus is hi...
