Embodiment Construction

[0022] Such as figure 1 As shown, the dual-purpose rain and sewage landscape ecological purification system consists of a lower biochemical treatment system (hereinafter referred to as biochemical pool) and an upper surface flow constructed wetland treatment system. The aspect ratio of the entire constructed wetland ecological purification system is 2:1~3: 1. The depth is 2.5-3m.

[0023] The biochemical pool is provided with a water collection pool 7, a hydrolysis pool 6, an aerobic pool 25 and a clear water pool 20. The sump pool, hydrolysis pool, aerobic pool and clean water pool are independent spaces separated by walls.

[0024] The upper surface flow constructed wetland treatment system consists of a primary filter, a middle baffle constructed wetland and a final filter. The primary filter, intermediate baffle constructed wetland and final filter are also separated by walls.

[0025] The top of the sump pool is the primary filter, the top of the clean water pool is th...

Abstract

The invention discloses a rain and sewage dual-purpose landscape type ecological purification system. The system comprises an upper-layer surface flow constructed wetland treatment system and a lower-layer biochemical treatment system, wherein all the bottoms of a primary filter tank, a final filter tank and a baffling constructed wetland of the upper-layer surface flow constructed wetland treatment system are paved with filter paddings; plants are planted on the primary filter tank, the final filter tank and the baffling constructed wetland; a water collecting tank, a hydrolyzing tank, an aerobic tank and a clean water tank of the lower-layer biochemical treatment system are separated by adopting walls; the separating wall of the water collecting tank and the hydrolyzing tank is provided with a channel; the hydrolyzing tank and the aerobic tank are provided with drainage pipelines communicated to the upward side of the constructed wetland; the aerobic tank is provided with an exhaust pipeline extending to the air; the primary filter tank is arranged above the water collecting tank; water inlet holes communicated with the water collecting tank are uniformly formed in the bottom of the primary filter tank; the final filter tank is arranged above the clean water tank; water inlet holes communicated with the clean water tank are uniformly formed in the bottom of the final filter tank; the baffling constructed wetland is arranged above the hydrolyzing tank and the aerobic tank.

Description

technical field [0001] The invention relates to a rain and sewage dual-purpose landscape type ecological purification system. Background technique [0002] In recent years, with the shortage of water resources, the treatment of domestic sewage for water resource reuse has gradually become a hot spot. Compared with other sewage treatment systems, artificial wetland treatment technology has gradually become the mainstay of water treatment due to its many advantages such as increased green area, low operating costs, simple maintenance and management, little impact on the surrounding environment, decentralized and miniaturized construction, etc. Hotspots are widely used to remove organic pollutants and nutrient pollutants such as nitrogen and phosphorus. However, compared with the conventional sewage treatment technology, the constructed wetland treatment system has disadvantages such as unstable treatment effect, poor sustainability, and strong seasonal influence. [0003] In...
