Problems solved by technology

[0005] The purpose of the present invention is to overcome the fact that the sewage ecological treatment system in the prior art mainly relies on plant roots to absorb and remove pollutants, the treatment capacity is limited, and the treatment effect cannot meet the requirements. To deal with the problems of large and high operating costs, we provide an ecological treatment system for exogenous sewage, which combines biological treatment and physical treatment through a rational layout to improve the treatment effect on water pollutants. The layout is reasonable, the space utilization is high, and installation and maintenance are easy. Convenient, low operating cost, while ensuring the effect of sewage treatment and river landscape

Embodiment 1

[0052] The adsorption filler in the physical treatment area adopts waste brick powder.

Embodiment 2

[0054] The adsorption filler in the physical treatment area uses a mixture of waste brick powder and nano-titanium dioxide with a mass ratio of 150:1.

Embodiment 3

[0056] The adsorption filler in the physical treatment area adopts modified waste bricks, and the preparation method of the modified waste bricks includes the following steps:

[0057] (1) After cleaning, crushing and sieving the waste bricks of construction, the waste brick powder with particle size is obtained;

[0058] (2) Mix waste brick powder with a mass ratio of 150:1 and nano-titanium dioxide to obtain a mixture, add 11mol / L nitric acid solution, the mass volume ratio of the mixture to the nitric acid solution is 1g:45mL, stir and react at 75°C for 10h, filter, Drying after washing to obtain the carboxylation mixture;

[0059] (3) Add excess thionyl chloride to the carboxylation mixture, reflux at 78°C for 4 hours, and distill off the thionyl chloride under reduced pressure to obtain the acid chloride mixture;

[0060] (4) Disperse the acid chloride mixture in dichloromethane, add aniline at 0°C, keep warm for 11 hours, filter, wash, and dry to obtain the amidation mi...

Abstract

The invention relates to the field of water body ecological treatment, and discloses an exogenous sewage ecological treatment system which comprises a biological treatment area arranged in a water body near a sewage draining exit, a physical treatment area surrounding the biological treatment area and the sewage draining exit to form a closed area, and an aeration device used for aerating the bottom of the biological treatment area, wherein the biological treatment area comprises an ecological floating island arranged on the water surface and used for planting aquatic plants and a microorganism growth ecological base connected to the lower portion of the ecological floating island, and the physical treatment area comprises a supporting layer located at the bottom of a water body, an adsorption filler layer arranged on the supporting layer and a plant layer arranged on the adsorption filler layer. According to the invention, biological treatment and physical treatment are combined, so that the removal efficiency of water pollutants is improved, the layout is reasonable, and the space utilization rate is high; modular installation is achieved, installation is efficient and rapid, maintenance is easy and convenient, and the impact resistance of the system is high; solar energy is used for supplying power, extra power is not needed, and operation cost is low.

Description

technical field [0001] The invention relates to the field of ecological management of water bodies, in particular to an ecological treatment system for exogenous sewage. Background technique [0002] In recent years, with the continuous acceleration of the urbanization process, the amount of pollutants absorbed by urban rivers and lakes is increasing. Although the comprehensive water treatment project is constantly being carried out, due to the incomplete interception and management of sewage and the incomplete treatment of initial rainwater in some areas Due to the lack of natural runoff of rivers and lakes and the limited self-purification ability of water bodies, the water quality of most rivers and lakes has gradually deteriorated, and the ecosystems of rivers and lakes have been destroyed, seriously affecting water quality and exacerbating the problem of water pollution in our country. [0003] At present, methods such as sewage interception, dredging, and bank revetme...
