Problems solved by technology

In addition, the water flow of the landscape water body is relatively slow, the water body of the waterscape is shallow, there are dead spots in the flow, and the initial rainwater pollution is serious, all of which are obstacles to the application of urban reclaimed water to the landscape water body
If the treatment is not good, it will cause eutrophication of the water body and the continuous deterioration of the water ecological environment. In the sensory sense, the algae in the wat

Embodiment Construction

[0025] The flow chart of the specific treatment method for urban reclaimed water applied to landscape water bodies of the present invention is shown in the accompanying drawings.

[0026] 1. First, build an ecological sedimentation pond and supporting coagulation sedimentation ponds

[0027] (1) Establish an ecological sedimentation pond: the outlet of the urban reclaimed water is designed in the middle and upper part of the ecological sedimentation pond, and the bottom elevation of the pond is 2m lower than the outlet of the reclaimed water. The water capacity of the ecological sedimentation pond is about 1500 times of the reclaimed water discharge flow~ 2000 times; the depth of the ecological sedimentation pond is 1000cm, based on the mountain stone, 200-800㎜ grain size rubble plus 30-50㎜ crushed stone and original soil are mixed and built in a ratio of 6:2:2, the ecological sedimentation pond The top width is 10-15m, and an ecological filter dam with a height of 3m is set i...

Abstract

The invention discloses a treatment method for applying urban reclaimed water to landscape water. The method mainly comprises the following steps of: building an ecological precipitation pond and a facultative anaerobic deep water pond, constructing an ecological aeration dam, and building a submerged plant purification pond, an aquatic plant purification pond, and an artificial wetland buffer zone; and allowing the urban reclaimed water to sequentially flow through the ecological precipitation pond, the facultative anaerobic deep water pond, the ecological aeration dam, the submerged plant purification pond, the aquatic plant purification pond and the artificial wetland buffer zone to obtain the treated water which is used as the landscape water. According to the urban reclaimed water which is treated by the method, the transparency is more than 0.5m, and dissolved oxygen is more than 2mg/L, and floater and fishy odor are avoided; and the landscape water completely meets the B and C-class water-quality standard of the landscape and entertainment water which is allowed to be contacted.

Description

technical field [0001] The invention relates to the in-depth treatment and application of urban reclaimed water, in particular to a treatment method for urban reclaimed water applied to landscape water bodies. Background technique [0002] Reclaimed water, also known as reclaimed water, refers to water that can be used beneficially after proper treatment to meet certain water quality indicators and meet certain use requirements. A large amount of reclaimed water is used for landscape water. Urban reclaimed water used in landscape water bodies can be divided into recreational landscape water bodies that should be partially contacted and ornamental landscape water bodies that are not allowed to be touched according to the nature of the water bodies. [0003] The characteristics of urban reclaimed water are: after advanced treatment, the sewage is still quite nutritious, and the water quality of reclaimed water produced by sewage treatment plants in various places generally bel...
