Embodiment 1

[0037] The experimental site is part of the independent waters of an artificial lake in a community. The water volume of this independent water area is 450-510m 3 . The water quality is as follows: ammonia nitrogen is 3.34±0.05mg / L, and total phosphorus is 0.29±0.09mg / L. Referring to the surface water environmental quality standard (GB3838-2002), the landscape water belongs to inferior V class water.

[0038] Single factor water quality assessment results of influent water

[0039]The device of the present invention is set on the surface of the artificial lake, and the device is arranged in concentric circles, see Figure 1-2 , the landscape water to be treated is lifted into the reaction device by the submersible pump, and first flows through the primary filter device to filter out large particles of impurities and suspended solids in the water.

[0040] The filtered landscape water continues to flow into the biological phosphorus removal device, where carbon removal and p...

Embodiment 2

[0050] The experimental site is the water area of ​​an artificial lake in a certain city. The water volume of this independent water area is 7300-9200m 3 . The water quality is as follows: ammonia nitrogen is 2.56±0.05mg / L, and total phosphorus is 0.32±0.09mg / L. Referring to the surface water environmental quality standard (GB3838-2002), the landscape water belongs to inferior V class water.

[0051] After half a year of treatment, the net bag in the adsorption reaction device is taken out, and then the particulate matter in the net bag is cleaned and dried, and then applied to the landscape land for use, which can continuously replenish soil nitrogen and phosphorus, and increase the concentration of soil organic carbon, economic benefits and Significant environmental benefits.

Abstract

The present invention is to provide a landscape water treatment device with nitrogen and phosphorus recovery function, recycle nitrogen and phosphorus in eutrophic water body, and prepare sludge slow-release fertilizer suitable for application from sewage plant sludge and nitrogen and phosphorus therein, It not only solves the problem that a large amount of sludge cannot be reasonably disposed of, but also rationalizes nitrogen and phosphorus resources, which not only reduces environmental pollution, but also brings new benefits to the enterprise.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a landscape water treatment device with nitrogen and phosphorus recovery functions. Background technique [0002] With the rapid development of China's social economy and the continuous improvement of residents' living standards, the scale of urban landscape water bodies such as aquariums and artificial lakes is constantly expanding. Landscape water itself generally has no fluidity, limited reoxygenation capacity, and poor self-purification ability of water body. The trend of eutrophication of water bodies is intensifying, and the removal of nutrients such as nitrogen and phosphorus has become the main pollutant in urban landscape water bodies. How to ensure the quality of landscape water is a difficult problem that people are facing. The existing sewage treatment plant treatment process is not suitable for the treatment of landscape water. Moreover, limited by land area...
