Embodiment Construction

[0022] see figure 1 and figure 2 , The ecological purification ditch includes a water inlet pipe 1, a water inlet area 2, a purification area 3, a water collection and reuse well 4, a water outlet area 5 and an outlet pipe 6. The front and end of the ecological purification ditch are the water inlet area 2 and the water outlet area 5. Between the water inlet area 2 and the water outlet area 5, a multi-stage purification area 3 is set in series. Water collection and reuse wells 4 are set between the purification areas. Set gravel fillers and plants in each purification area, and gradually reduce the gravel particle size in the purification area from front to back along the ecological purification ditch. A partition wall is also provided in the purification area 3, and holes are formed on the top or bottom of the partition wall to make the water flow form up and down deflections. The end of the ecological ditch is connected to the water outlet area 5 and connected to the wat...

Abstract

The invention discloses an ecological purification ditch that integrates sewage transportation, purification and reuse, and consists of four parts connected in sequence, a water inlet area, a purification area, a water collection reuse well, and a water outlet area. Sewage enters the water inlet area of ​​the purification ditch, and after uniform water distribution, enters the purification area where the height of the bottom of the multi-stage canal gradually decreases. The oxygenation is strengthened through multi-stage water drops, and water collection and reuse wells are set between the adjacent purification areas of each level. The purification area is equipped with gravel fillers of different grades, and plants are planted, and the water outlet area and drainage pipes are set at the end to discharge the treated sewage into nearby water bodies. This ecological purification ditch is used for rural sewage transportation. It integrates the three functions of sewage transportation, treatment and reuse. It adopts biological-physical-chemical-plant synergistic purification and natural falling water enhanced oxygenation technology, which has high treatment efficiency and low energy consumption. , less land occupation, convenient management, flexible layout, good landscape effect and so on.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a channel type ecological purification ditch. Background technique [0002] At present, with the continuous construction of new countryside in our country, the problem of rural sewage treatment has gradually emerged. Conventional urban sewage treatment facilities require large investment, high operating costs, and complex operation and management, and are not suitable for rural sewage treatment. In recent years, the research on rural sewage treatment technology is still in its infancy, and there are few published technologies. For example, 200920013004.8 "Unitized Membrane and Biological Decomposition Rural Sewage Treatment Station", 200910060176.5 "Composite Constructed Wetland Treatment Process for Domestic Sewage in Rural Townships" and 200910236389.9 "Alternative Vertical Flow Constructed Wetland Rural Sewage Courtyard Lands...
