Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with specific implementation methods.

[0031] An embodiment of the present invention provides a long-term control method for eutrophication in a wetland front pond, the method comprising:

[0032] 1. In the initial stage of ecosystem construction, in order to quickly improve the habitat, the following measures should be taken first:

[0033] Suspend bio-bricks in the front pond water body. Bio-bricks are black waxy solids that match microbial concentrates with solid paraffin in a certain proportion. The size and shape can be made according to actual needs; they can be used for bacteria (Bacillus and other heterotrophic bacteria) The pores provide growth space, provide nutrients for its rapid growth, and degrade pollutants in water. When installing bio-bricks, you only need to calculate the dosage according to the specific conditions of the wat...

Abstract

The invention relates to a wetland pre-pond eutrophication control method which comprises the following steps: at the early stage of ecological system construction, biological bricks, a phosphorus locking agent and a circulating aeration device are applied to quickly improve the water quality and the substrate of a pre-pond; after the water ecosystem is rapidly restored, the plants are systematically planted in the pre-pond water, the bottom and the bank, after the clear water steady-state shallow lake ecosystem based on the submerged plants is gradually formed, rapid improvement measures aregradually reduced and even omitted, and the project is periodically maintained. With application of the control method, water-bottom-bank systematic habitat optimization can be conducted on the pre-pond, natural construction and gradual improvement of the clear water steady-state shallow lake ecosystem are promoted, and thus eutrophication of the pre-pond is prevented for a long time.

Description

technical field [0001] The invention relates to the field of water ecological restoration, in particular to a method for controlling eutrophication of a wetland front pond. Background technique [0002] Constructed wetland is a kind of controlled dosage of sewage into the filler with aquatic plants in an artificial way. According to different control methods and different residence times, it flows along a certain direction. Under the combined action of physics, chemistry and biology It is a sewage treatment technology that purifies water quality through the joint action of adsorption, precipitation, ion exchange, plant absorption and microbial degradation. Constructed wetlands, as an important engineering measure in the process of river basin water environment management, play an important role in purifying water bodies and improving water quality in river basins. They have the advantages of high efficiency, low operation and maintenance costs, and strong impact load resista...
