Embodiment 1

[0027] Embodiment 1 A drainage open channel for rural sewage pretreatment, wherein: the drainage open channel includes side titanium dioxide water slurry plastering surface 1, M7.5 water slurry standard brick 3, water slurry plastering surface 4, C15 concrete cushion layer 5; Bottom titanium dioxide water slurry plastering surface 6; rubble support layer 7 and so on. The walls on both sides of the open channel are made of M7.5 water slurry standard bricks 3 with a laying thickness of 240mm; the bottom is made of C15 concrete cushion 5 with a laying thickness of 100mm; the inner surface of the open channel is laid with a layer of 15mm thick water slurry plastering surface 4 for Connect the wall body 3 and the rubble supporting layer 7; the rubble supporting layer 7 and the water slurry plastering surface 4 on the side wall are at a certain inclination angle α; the surface of the rubble supporting layer 7 is laid with a layer of side titanium dioxide water slurry 1 with a thickne...

Embodiment 2

[0033] An open drainage channel for rural sewage pretreatment, wherein: the basic structure of this embodiment is the same as that of embodiment 1, and the difference is: the inclination angle α of the side titanium dioxide water slurry plastering surface 1 from the canal top to the canal bottom is 10° . The rest are the same as in Example 1.

Embodiment 3

[0035] An open drainage channel for rural sewage pretreatment, wherein: the basic structure of this embodiment is the same as that of embodiment 1, and the difference is: the inclination angle α of the side titanium dioxide water slurry plastering surface 1 from the canal top to the canal bottom is 20° . The rest are the same as in Example 1.

Abstract

The invention discloses a rural sewage drainage pretreatment open channel. The open channel mainly comprises a side edge titanium dioxide water slurry plastered face, M 7.5 water wet masonry standard bricks, a water slurry plastered face, a C 15 concrete cushion layer, a bottom titanium dioxide water slurry plastered face and a rubble supporting layer. Rural sewage flows in the drainage open channel, so that pretreatment is conducted on the sewage. Compared with a common drainage open channel, the rural sewage drainage pretreatment open channel can well remove organic matter and nitrogen and phosphorus pollutants in the rural sewage and has the advantages of being good in treatment effect, free of toxin, safe, good in stability, fast in effect generation, low in energy consumption, reusable, simple in structure, high in adaptability and the like. The rural sewage drainage pretreatment open channel is suitable for pretreatment of the rural sewage and pretreatment of domestic wastewater or industrial wastewater in urban open channels.

Description

technical field [0001] The patent of the present invention relates to an open channel for pretreatment of rural sewage drainage, specifically an open channel for treating rural sewage by photocatalytic treatment of nano-titanium dioxide. Background technique [0002] The distribution of rural population is scattered and the number is large. Generally, there is a lack of domestic sewage collection and treatment facilities. The sewage is washed with rainwater. The surface water, soil water and groundwater bodies flow into rivers, lakes, ditches, ponds, reservoirs and other surface water bodies, soil water and groundwater bodies from the surface. It is estimated that more than 8 billion tons of sewage are produced in the whole surrounding countryside every year, which seriously pollutes the surrounding lakes and rivers, affects the living environment in rural areas, endangers the health of farmers, and causes immeasurable economic losses. worry. [0003] Rural sewage mainly i...
