Embodiment 1

[0083] Embodiment 1 A kind of campus rainwater ecological purification integrated treatment method described in the present invention comprises the following steps:

[0084] 1) An integrated treatment system for campus rainwater treatment is pre-built in the campus;

[0085] 2) Choose the appropriate treatment method according to the ecological purification of different water bodies in the campus:

[0086] For the initial rainwater runoff of the campus, the subsurface constructed wetland system in the integrated treatment system is used for treatment;

[0087] For the campus storm runoff, use the coastal zone interception system in the integrated treatment system for treatment;

[0088] For the water body of the natural revetment river in the campus, the ecological floating bed-aeration push flow system in the integrated treatment system is used for treatment;

[0089] For the water body of the hard revetment river in the campus, the artificial aquatic plants-microporous aerat...

Embodiment 2

[0121] Embodiment 2 The ecological purification integrated system constructed according to the campus rainwater ecological purification integrated treatment method described in Embodiment 1, including the subsurface flow artificial wetland system for processing the initial rainwater runoff of the campus, and the coastal zone interception for processing the campus stormwater runoff System, ecological floating bed-aeration push flow system for treating the water body of the natural revetment river on campus, artificial aquatic plants-microporous aeration system for treating the water body of the hard revetment river on the campus, biological manipulation-fountain for treating the water body of the closed pond on the campus aeration system,

[0122] The constructed wetland system includes a subsurface flow constructed wetland 1, an anaerobic pretreatment pool 2, a number of grid wells 3 distributed in the campus, and a replenishment water intake system. A liquid level lift pump is...

Embodiment 3

[0132] Example 3 with Figures 15-19 As an example, the artificial water plants 5 adopt carbon fiber grass 55 as a reinforced membrane, and the carbon fiber grass 5 is fixed on the nylon rope 53 between the steel pipe frames 52 made up of stainless steel piles with tie bars 51, and the lower end is hung Weight 54 to make it sag evenly; stainless steel piles are made of φ60 304 stainless steel, each length is 2m, and a φ25 fixing hole 56 is drilled at the top 10cm, and the steel pipe is required to be driven into the underground part ≥ 1.5m during installation; stainless steel piles Use φ60 304 stainless steel, each with a length of 2m, and drill a φ25 fixing hole at the top 10cm. When installing the steel pipe, it is required to drive into the underground part ≥ 1.5m.

Abstract

The invention discloses a campus rainwater ecological cleaning integrated-processing method and an ecological cleaning integration system. The method comprises the following steps: 1) establishing an integration processing system for processing campus rainwater in a campus in advance; 2) selecting a proper processing method according to ecological purification conditions of different water bodies in the campus; and 3) finally collecting rainwater processed in the step 2) to a landscape water body in the campus, or discharging into a river in the campus, or collecting into the underground water layer of the campus. The system comprises an undercurrent type artificial wetland system for processing campus initial-stage rainfall runoff, a shoreland-area closure system for processing campus storm runoff, an ecological floating bed-aeration plug-flow system for processing campus natural revetment river water body, an artificial waterweed-micropore aeration system for processing campus hard revetment river water body, and a biomanipulation-fountain aeration system for processing campus enclosed pond water body. The beneficial effects comprise that the purification effect is good, the cost is low, the resource utilization rate is high and the purification effect is lasting.

Description

technical field [0001] The invention relates to an integrated treatment method and system for campus rainwater ecological purification, belonging to the technical field of environmental engineering. Background technique [0002] Urban surface rainfall runoff carries a large amount of surface pollutants into the rainwater collection system, which has become one of the main reasons for the deterioration of urban water quality. Due to the discontinuous and explosive transport of urban rainwater runoff pollutants, its pollution load will increase exponentially in a short period of time, which will have a shocking impact on urban water bodies. Water pollution incidents after heavy rain in many cities are very serious Good illustration. [0003] At present, many university campuses in China are planning to build relatively independent campus water systems. On the one hand, the campus water system is conducive to flood control and drainage in the rainwater collection area, and ca...
