Embodiment 1
[0029] In the present embodiment, water celery handles the method for outfall sewage, specifically carries out according to the following steps:
[0030] (1) Sampling and testing the target water body to be purified at the same time for three consecutive days: the sewage outfall. The sewage outfall is a typical residential sewage outfall. The analysis indicators are CODcr, ammonia nitrogen, total phosphorus and total nitrogen. As shown in the table below:
[0031] Table 1 Analysis indicators of domestic sewage at sewage outlets
[0032] project CODcr Ammonia nitrogen Total Phosphorus flow value 251mg / L 13.7mg / L 2.3mg / L 50 tons / day
[0033] The target effluent quality is Grade A, so K is 3, M=50, and the required planting amount of water celery is W=M×0.025×K=50t×0.025×3=3.75t;
[0034] (2) according to the water celery planting amount calculated in the step (1), adopt soilless cultivation, the adult seedling of water celery is tiled on the ...
Embodiment 2
[0040] This embodiment is designed for the water quality improvement function of surface landscape water. Through the growth of water celery, the nitrogen and phosphorus elements in the surface water body are greatly reduced, making the water body thinner. In addition, due to the shading effect of the floating bed, it can greatly Inhibits the growth of cyanobacteria. Specifically follow the steps below:
[0041] (1) The target water body to be purified at the same time for three consecutive days: a lake bay selected from an inner lake in a certain city is sampled and analyzed. The average area of the bay is 20,000 square meters, the water depth is 1.5 meters, and the total water volume is 30,000 tons. The analysis indicators are CODcr, ammonia nitrogen, total phosphorus and total nitrogen, as shown in the table below:

Embodiment 3
[0053]This embodiment is mainly designed for the blackening and deodorization of black and odorous rivers in cities. Because small rivers in cities are basically artificial rivers, their banks and riverbeds are all hard bottoms and lack ecological support. Therefore, sewage enters this Due to the incomplete ecosystem, metabolism and transformation cannot be carried out after this type of river course. Therefore, the use of floating beds can solve the problem of plant root fixation, and the high pollution resistance of water celery enables effective absorption and treatment of high-concentration sewage, which is part of the Microorganisms provide a living environment.
[0054] This embodiment proceeds according to the following steps:
[0055] (1) This embodiment selects a typical black and smelly river course in a certain city. The prominent feature of this river course is that the water color is black, and it emits a pungent odor without fluidity. The water body was sampled ...
