Embodiment Construction

[0022] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] figure 1 It is a process drawing of the present invention for controlling eutrophication of landscape water body.

[0024] The present invention provides a process for controlling eutrophication of landscape water body. The process for controlling eutrophication of landscape water body is to comprehensively utilize chemical methods and biological methods to remove pollutants in the water body. The specific process is carried out in sequence as follows:

[0025] 1) First, evenly add the microbial composite bacterial agent to the landscape water body, the microbial composite bacterial agent mixes with the water body through natural settlement and free diffusion, and removes organic matter and ammonia nitrogen in the water body through the degradation of the microbial composite bacterial agent;

[0026] 2) Next, on the 10th day after adding the micr...

Abstract

The invention discloses a process for treating landscape water eutrophication, which sequentially comprises the following steps of: 1) firstly, uniformly adding a composite microbial agent into landscape water; 2) secondly, after 10 days, uniformly adding a chemical dephosphorization medicament into the landscape water; and 3) finally, in the next day, placing an artificial floating island in the middle of the water, and planting aquatic plants on the artificial floating island to absorb nitrogen and phosphorus in the water by using the root systems of the aquatic plants. The process has the advantages that: a chemical method and a biological method are comprehensively utilized to remove pollutants from the water, namely a microbiological purification method, a chemical dephosphorization method and an aquatic plant repairing method are integrated, so that organic matters and ammonia nitrogen are removed from the water, the phosphate release of mud at the bottom is controlled, and the total nitrogen removing effect is good. Bad V class water is finally purified to meet the standard of V class water by the process according to the spatial and time effects of three kinds of complementary technology.

Description

technical field [0001] The invention relates to a process for treating eutrophication of landscape water bodies. Background technique [0002] As far as the commonness of water pollution is concerned, urban sewage treatment technology can be used to purify landscape water bodies. However, because most of them are moderate to light pollution, with obvious occurrence periods and high aesthetic requirements, it is not suitable to directly use urban sewage treatment technology to control and treat them. In recent years, my country has carried out some active research and attempts on the purification and treatment of sewage ponds and rivers. From the perspective of technical principles, there are mainly three categories: physical methods, chemical methods, and biological-ecological methods. The above three categories of purification technologies all have different advantages and disadvantages. [0003] 1) Physical methods include: [0004] ①Artificial oxygenation: Artificial ox...
