Problems solved by technology
However, these landscape settings are arbitrary, and at the same time ignore the comprehensive consideration of long-term maintenance of water quality, which urgently needs a stormwater runoff control and pollution treatment method combined with natural landscape construction to reduce urban stormwater runoff, purify rainwater quality, and be able to Keep water clean for a long time

[0034] The following landscapes are included in descending order of terrain:
[0035] (1) Ecological landscape reservoir, water depth 1.2m, hydraulic retention time 2h, hydraulic load 3 / m 2 ·D; (2) Stacked water purification pool, rockery stacking water is 2m high, and the pool side is 1m 2 Mixed planting of reed bamboo, canna and palm bamboo; (3) Landscape filter with a length-to-width ratio of about 3, hydraulic retention time ≥6h, and hydraulic load: 3 / m 2 ·D. The bottom of the pool is a rammed soil layer, on which is laid a 20cm-30cm thick gravel layer with a particle size of 10-20mm. The uppermost part is made of zeolite with an average particle size of about 15mm and a depth of about 15cm. The uppermost part has a particle size of 30-50mm. Pebble, scattered in the pool, plant floating water plants with water lilies, emergent plants including calamus, windmill grass, water arrowroot, etc., submerged plants are mainly planted in myriophyllum, planted in concentric circles, a...

Abstract
The invention relates to the field of environmental management, in particular to a system for improving surface runoff water quality through optimizing landscape. The system comprises (1) an ecological landscape water reservoir, (2) folding water purification, (3) a landscape filter tank, and (4) a pebble pool. According to the system, the landscape effect of various landscape engineering and aesthetic effect of water circulation are integrated and the internal mechanism for affecting the water quality is analyzed, the advantages of various creatures in nature are greatly integrated while the water quality is maintained and improved; the synergistic effect of plants, animals and microorganism is adjusted in a reasonable manner, the landscape coordination around the engineering is highlighted and applied coordinately, the ecological benefits are brought to the largest extent and the dynamic equilibrium of the process system can be maintained simultaneously.
Description
Technical field [0001] The present invention relates to the field of environmental governance, in particular to a system for improving surface runoff water quality by optimizing landscape. Background technique [0002] With the acceleration of urbanization, the impervious area is increasing year by year. This not only increases the stormwater runoff, but also shortens the time of convergence. A large amount of stormwater runoff is collected in a short period of time through urban stormwater pipelines. On the one hand, it increases the pressure on the urban drainage network, and on the other hand, it also wastes rainwater resources that could be supplied to urban groundwater. In addition, urban rainwater runoff contains a large amount of pollutants leached from the air and the ground, making it an important source of surface water pollution. Urban rainwater runoff has the characteristics of strong randomness, large amount of pollution, and wide distribution area, so it is very d...
