Problems solved by technology

Artificial biological floating island materials are mostly foamed plastics, floating beds made of plants, etc. Some of these floating beds will cause secondary pollution, some are expensive, and some are time-consuming and laborious. In order to solve this problem, research and development of water surface cultivation water spinach method

Embodiment Construction

[0010] 1. Take the main vine of water spinach with all leaves removed, and put it into the area surrounded by bamboo and other objects that can float on the sewage surface. The water spinach will gradually form a large and vigorous perennial root in the sewage. With the help of the buoyancy of its own hollow stem, Grows on water. When the water spinach grows more than 15 cm above the water surface, keep 2 to 3 stem nodes to pick the upper part of the water spinach, remove all the leaves of the picked water spinach, and continue to put it into the sewage for cultivation. After three times of picking, the original main vine part is salvaged and put into the heart Remove all the leaves of the vegetables and continue to put them into the sewage for cultivation. After three times of picking, the original main vines are salvaged and composted to avoid secondary pollution to the water body caused by excessive reproduction and plant rot.

Abstract

The invention relates to application of a method for cultivating water spinaches on a water surface in controlling sewage, which belongs to the field of engineering ecology studies. The water spinaches with very strong capacity of absorbing nitrogen, phosphonium and the like in a water body are adopted as the main body of an artificial biological floating island; by making use of the buoyant forceof hollow stalks, the water spinaches can float and grow on the water surface without any platforms to avoid the abuses of secondary pollutions to the artificial biological floating island, high manufacturing cost, time and labor wastes and the like, thereby effectively removing the over-high nitrogen and phosphonium concentrations in the water body to achieve the aim of controlling and restoringthe water body eutrophication. An area surrounded by bamboos and any other subjects or fences and the like which can float on the surface of the sewage is convenient for management and beautificationmolding, and the main vines after three times of picking are fished out for composting so as to avoid the secondary pollution to the water body caused by plant decay. The method for cultivating the water spinaches on the water surface can be used for controlling domestic sewage and paper making wastewater.

Description

technical field [0001] This technology belongs to the field of engineering ecology research technical background [0002] With the development of economy and the increase of urbanized population, a large amount of production and domestic sewage is directly discharged into rivers and lakes without treatment, which puts great pressure on these water bodies, resulting in a sharp deterioration of water quality. Due to the continuous increase of nutrients such as nitrogen and phosphorus discharged into the water body, the eutrophication process of the water body is accelerated. The use of artificial biological floating islands is a good way to control and restore eutrophication in water bodies. Artificial biological floating islands absorb nutrients directly from water bodies and treat sewage in situ without occupying additional land. At the same time, floating islands can adapt to various The depth of water makes plant management and harvesting easier. Therefore, the research ...
