Problems solved by technology
[0005] In engineering practice, unreasonable planting density of submerged plants will lead to an increase in the cost of water ecological management and subsequent repair and maintenance
If the planting density of submerged plants is insufficient, the water purification effect will be poor or the survival rate of plants will be low; if the planting density of submerged plants is too high, there will be vicious competition for plant growth, poor plant development, and poor water landscape effect

Embodiment Construction
[0038] The present invention will be described in detail below in conjunction with the embodiments.
[0039] (1) Preliminary preparation stage
[0040] 1. This method uses the undisturbed soil at the construction site of the corresponding water ecological restoration project, and exposes it to the sun for 24 hours for later use, so as to kill pests and bacteria and promote the volatilization of water in the soil. Specifically, in the water ecological environment to be restored, shoveling, using boxes to store soil, manual soil transportation, transportation soil transportation, soil loosening and original soil exposure and other treatment methods.
[0041] In this example, the undisturbed soil was spread out, and the soil was continuously loosened and turned over for full exposure to the sun, which was conducive to the complete evaporation of water in the undisturbed soil and prevented water from affecting the test sewage proportioning results. In addition, strong ultraviolet...

Abstract
The invention discloses an indoor test process for purifying water by submerged plants, which is characterized by specifically comprising the following steps of bottom mud preparation: taking undisturbed soil in a to-be-remediated water ecological environment, and sterilizing to obtain bottom mud, test sewage preparation: directly adopting sewage in a to-be-remediated water ecological environmentor diluting domestic sewage for simulation to obtain test sewage, cultivation box treatment: taking a plastic box as a cultivation box, pumping bottom mud into the cultivation box, and pouring test sewage into the cultivation box to obtain a plurality of cultivation box bodies, submerged plant planting: changing single submerged plant planting according to planting density setting, and enabling each box body to correspond to one planting density, planting the combined submerged plants according to an orthogonal test method, and formulating a planting scheme, regularly extracting a water samplein each cultivation box body, and monitoring the water quality. The scientificity and reliability of submerged plant water quality purification indoor tests are improved. The water quality purification effects and optimal planting density data of the three submerged plants are quantitatively evaluated according to test results.
Description
technical field [0001] The invention belongs to the technical field of water ecological restoration plant research, and in particular relates to an indoor test process for purifying water quality by submerged plants. Background technique [0002] At present, in the field of water purification, there are three main types of water restoration technologies at home and abroad: ① chemical methods; ② physical methods; ③ biological-ecological methods. In comparison, the bio-ecological approach has obvious advantages. It is a water restoration technology with low energy consumption and low investment. At the same time, it is environmentally compatible, has no risk of secondary pollution, and has a certain landscape effect. [0003] Submerged phytoremediation, as the most widely used bio-ecological restoration, mainly achieves water purification effect through three aspects: 1) Submerged plants absorb nitrogen, phosphorus, etc., reducing pollutants in water; 2) Submerged plants simu...
