Problems solved by technology

The current restoration methods for water ecology can only temporarily improve the water body environment, with high investment costs and little return. Therefore, it is necessary to provide an effective composite water ecology restoration method, which can improve the condition of the water ecosystem from multiple aspects , and through the mutual cooperation between various improvement aspects, multi-level and self-circulating improvement can be realized, so as to completely improve the state of the water body.

Embodiment 1

[0071] The present embodiment provides a kind of composite water ecological restoration method, comprises the following steps:

[0072] S1. Habitat creation: including leveling the soil, adjusting the soil particle size to ≤1cm, adjusting the soil porosity to ≥60%, removing construction slag, branches and garbage and other substances that affect the water body, and adjusting the slope ratio to ≤1:2.

[0073] S2. Sprinkling of substrate improving agents: sprinkle substrate improving agents after precipitation. Base improvement agents include 45g / m3 of soil disinfectant, 11g / m3 of trace element nutrient, and 18g / m3 of freeze-dried powder of bottom-improving microorganisms.

[0074] Wherein, the soil disinfectant includes a soil disinfectant and a pH regulator, and the mass ratio of the soil disinfectant and the pH regulator is: 1:2. The trace element nutrient includes magnesium, iron, zinc, potassium, copper, calcium and manganese, and the mass ratio is 5:16:5:17:18:37:3. The ...

Embodiment 2

[0088] The present embodiment provides a kind of composite water ecological restoration method, and the difference with embodiment 1 is:

[0089] S2. Sprinkling of substrate improving agents: sprinkle substrate improving agents after precipitation. Base improvement agents include 55g / m3 of soil disinfectant, 5g / m3 of microelement nutrient, and 24g / m3 of freeze-dried powder of bottom-improving microorganisms.

[0090] Wherein, the soil disinfectant includes a soil disinfectant and a pH regulator, and the mass ratio of the soil disinfectant and the pH regulator is: 1.5:2. The trace element nutrient includes magnesium, iron, zinc, potassium, copper, calcium and manganese, and the mass ratio is 7:11:10:13:22:33:5. The modified microbial freeze-dried powder includes Bacillus subtilis, EM bacteria, photosynthetic bacteria, lactic acid bacteria and nitrifying bacteria, and the mass ratio is 34:14:27:8:19.

[0091] Add brown sugar and urea according to the mass ratio of modified mic...

Embodiment 3

[0100] The present embodiment provides a kind of composite water ecological restoration method, and the difference with embodiment 1 is:

[0101] S2. Sprinkling of substrate improving agents: sprinkle substrate improving agents after precipitation. The substrate improvement agent includes 50g / m3 of soil disinfectant, 8g / m3 of trace element nutrient, and 20g / m3 of freeze-dried powder of bottom-improving microorganisms.

Abstract

The invention discloses a composite water ecological restoration method, which comprises the following steps: a substrate improving agent is sprayed, an algae controlling organism is sprayed, a submerged plant community is constructed, an emergent floating leaf plant community is constructed, an aquatic animal community is constructed, and the transparency of a water body is improved. The composite water ecological restoration method can improve soil properties, improve soil fertility, improve light and oxygen content of the water body, degrade harmful substances in the water body, decompose macromolecule organic matter and small molecule organic matter, and clean, filter and purify water body, promote coordinated development and organic integration between various groups and surrounding environment, and form and maintain a stable clear water ecosystem.

Description

technical field [0001] The invention relates to the field of water ecological restoration, in particular to a composite water ecological restoration method. Background technique [0002] With the rapid advancement of urbanization and the improvement of industrial and agricultural production levels, the natural water ecosystem is seriously polluted, the water body is turbid, red tide floods, aquatic animals and plants die on a large scale, etc., which endanger the natural environment and seriously affect human production. life, so it is imperative to restore water ecology. The current restoration methods for water ecology can only temporarily improve the water body environment, with high investment costs and little return. Therefore, it is necessary to provide an effective composite water ecology restoration method, which can improve the condition of the water ecosystem from multiple aspects , and through the mutual cooperation between various improvement aspects, multi-leve...
