Ecological pond permeable barrier and ecological landscape water in-situ remediation method

Abstract

The invention discloses a permeable barrier and an ecological landscape water in-situ remediation method using the permeable barrier. The permeable barrier comprises a filtering material layer, a gravel layer and a gabion box, wherein the width of the filtering material layer is gradually changed; a layer of biological membrane is attached to the surface of the filtering material layer; the gravellayer is arranged on the outer side of the filtering material layer; the gabion box coats the outer side of the gravel layer; an impermeable material layer is laid at the upper end faces of the filtering material layer, the gravel layer and the gabion box; a soil layer is arranged on the impermeable material layer; plants are planted on the soil layer. According to the ecological landscape waterin-situ remediation method disclosed by the invention, adsorption and filtering of suspended particulate matters and dissolved nitrogen and phosphorus in a water body can be enhanced and the purification efficiency of water quality is improved; in addition, in the ecological landscape water in-situ remediation method, a plurality of permeable barriers are arranged in an ecological pond in a staggered manner, so that water current moves forward in a baffling form, and further the contact time between a water body and submerged plants can be prolonged; by dual filtering of the water body, the purification efficiency of the water quality is further improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an in-situ treatment method for ecological pond permeable walls and ecological landscape water. Background technique [0002] Among the landscape water treatment methods, the commonly used method is the ex-situ treatment method. The so-called ex-situ treatment method refers to the extraction of landscape water from the water body, and the treatment and then discharge back to the water body. And it should not be used when there is no excess land available for use in the surrounding area. In the prior art, conventional in-situ ecological treatment methods can also be used to purify landscape water. However, the common in-situ ecological treatment method only uses aquatic plants for purification. Due to the limited removal of nitrogen and phosphorus by plants, when the nitrogen and phosphorus content in the water is high, it cannot be effectively removed in a short time. ...

Problems solved by technology

However, the ordinary in-situ ecological treatment method only uses aquatic plants to purify. Since plants have limited removal effect on nitrogen and phosphorus in water, when the content of nitrogen and phosphorus in water is high, it cannot be effectively removed in a short time.
