Embodiment 1

[0025] An in-situ circulation treatment process for landscape lake water is composed of a surface runoff collection tank (1), an ecological infiltration tank (2), an enhanced purification unit (3), a circulation power system (4) and a landscape lake main water area (5). The surface runoff collection tank (1) is located at the lowest point around the landscape lake, and is connected with the ecological infiltration tank (2). The ecological infiltration tank (2) is located in the outermost circle of the landscape lake, and an enhanced purification unit ( 3), the circulation power system (4) is located in the center of the main water area (5) of the landscape lake.

[0026] The surface runoff collection tank (1) is composed of a canal body (1-1) and a cover plate (1-2); the canal body (1-1) is made of sponge concrete, and the permeability coefficient is 1mm / s; Said cover plate (1-2) is made of stainless steel material, and specification size is 400mm * 500mm, and thickness is 20m...

Embodiment 2

[0034] The difference between embodiment 2 and embodiment 1 is:

[0035] The ground runoff collection tank (1) is composed of a canal body (1-1), a cover plate (1-2) and a filter screen (1-3); the filter screen (1-3) is made of stainless steel, The size is 400mm×300mm, and the thickness is 10mm. The filter screen (1-3) is installed at the interface between the surface runoff collection tank (1) and the ecological infiltration tank (2), and its purpose is to intercept large-diameter stones or gravel impurities. Preliminary reduction of turbidity in surface runoff.

Embodiment 3

[0037] The difference between embodiment 3 and embodiment 1 is:

[0038] The raw materials for preparing the sponge concrete and their weight fractions include 120g parts by mass of aggregate, 15g parts by mass of cement, 5g parts by mass of binder, 0.5g parts by mass of foaming agent, 1g parts by mass of anti-cracking agent, Microbial agent is 1g mass part, water is 10g mass part; Described anti-cracking agent and microbial inoculum quality all increase to 1g from 0.5g; The increase of described anti-cracking agent quality can improve the intensity of sponge concrete, prolongs the strength of sponge concrete Service life; the increase in the quality of the microbial agent can speed up the water body treatment efficiency, effectively reduce the SS, ammonia nitrogen and other indicators in the water, and have more significant deodorizing and inhibiting algae breeding effects.

Abstract

The invention discloses a landscape lake water in-situ circulation treatment process, and belongs to the technical field of landscape water circulation purification. The process consists of a surface runoff collecting tank, an ecological percolation tank, an enhanced purification unit, a circulating power system and a landscape lake water main water area. The surface runoff collecting tank is located at the lowest position of the surrounding terrain of a landscape lake and communicated with the ecological percolation tank; the ecological percolation tank is located on the outermost circle of the landscape lake; the enhanced purification unit is arranged in a water inlet area of the landscape lake; and the circulating power system is located in the center of the landscape lake water main water area. Sponge concrete is used as a building material of structures such as the surface runoff collecting tank and the ecological percolation tank, and good conditions are provided for filtration and purification of lake water. The process is suitable for various urban landscape lakes, realizes in-situ circulation treatment of the lake water of the landscape lakes according to the characteristics and pollution conditions of the urban landscape water body and the green, ecological and environment-friendly design concepts, improves the water quality of the lake water of the landscape lakes, and has the advantages of low cost, simplicity in operation, sustainable development and the like.

Description

Technical field: [0001] The invention relates to an in-situ circulation treatment process of landscape lake water, which belongs to the technical field of landscape water circulation purification. Background technique: [0002] With the development of my country's economy, people's quality of life is constantly improving, and the requirements for living environment are getting higher and higher. In order to meet people's living needs, more and more landscape lakes have been added in cities. Since urban landscape water bodies are mostly closed slow-flowing water bodies with poor fluidity, lacking the self-purification function and ecological balance system of natural water bodies, and urban landscape lakes have the characteristics of small water area, small water environment capacity, and easy pollution, so landscape lakes are easy to become Storage body for rainwater and garbage. At present, the landscape lake water is mainly faced with the following pollution factors: orga...
