Embodiment 1

[0024] like figure 1 As shown, it is a process flow chart of a controlled-release capsule with the effect of denitrification and phosphorus removal in urban landscape water. A controlled-release capsule with the effect of denitrification and phosphorus removal in urban landscape water is composed of the following raw materials in weight percentage: the concentration is 3% Sodium alginate solution 1, mixed solution 2 composed of 1% aspartic acid, 5% humic acid, 35% glucose, and 59% water, the ratio of sodium algae solution 1 to mixed solution 2 is 1:1.

[0025] A preparation process of a controlled-release capsule having the effect of denitrification and dephosphorization of urban landscape water body is as follows:

[0026] In the first step, put the sodium algae solution 1 and the mixed solution 2 into the mixing tank 3, and enter the pressurized tank 4 after manual mixing;

[0027] In the second step, the compressed air tank 5 feeds 0.5 atmospheric pressure into the pressur...

Abstract

The invention relates to a controlled release capsule having nitrogen and phosphorus removal functions to urban landscape water, which is characterized in that the capsule comprises the following materials, in weight percentage: an algae sodium solution with concentration of between 3 percent and 10 percent, a mixed solution composed of aspartic acid, humic acids, glucose and water, the ratio of the algae sodium solution and the mixed solution is 1:1 to 1:3, and the preparation process thereof comprises that: the algae sodium solution and the mixed solution are put into a mixing tank and then into a pressurizing tank by artificial mixing, a compressed air tank inputs atmospheric pressure to the pressurizing tank, the solution is pressurized and extruded to enter a valve, the valve controls sizes of liquid droplets which are dripped into a storage tank filled with the calcium chloride solution, and the solution is agitated by a mechanical agitator to form elastic capsular particles. The controlled release capsule has the advantages of reducing environmental pollution and losses such as volatilization, losing and decomposition of active materials, and improving the physicochemical stability.

Description

technical field [0001] The invention relates to a controlled-release capsule capable of denitrification and phosphorus removal in urban landscape water, which can be used for urban landscape water treatment and belongs to the technical field of urban landscape water treatment. Background technique [0002] Urban landscape water refers to the water landscape located in the city for people's leisure and entertainment. Its forms include rivers, lakes, ponds, fountains, etc. With the continuous development of society and the continuous improvement of people's living conditions, landscape water is gradually integrated into the People's lives, but due to water pollution, the water quality of some landscape water gradually changes, and the two indicators of ammonia nitrogen and total phosphorus in the landscape water exceed the standard. [0003] At present, the commonly used treatment methods for controlling ammonia nitrogen and total phosphorus in landscape water bodies are: [...
