Example Embodiment

[0070] Example 1

[0071] The present embodiment provides a composite water ecological restoration method, comprising 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 substances that affect the water body such as building slag, branches and garbage, and adjusting the slope ratio to ≤1:2.

[0073] S2. Sprinkling of base improvement agents: after precipitation, sprinkle base improvement agents. The base improvement agents include soil disinfectant 45g / m3, trace element nutrients 11g / m3, and bottom-modified microorganism freeze-dried powder 18g / m3.

[0074] Among them, the soil disinfectant includes a soil sterilant and a PH regulator, and the mass ratio of the soil sterilant and the PH regulator is: 1:2. Micronutrients include magnesium, iron, zinc, potassium, copper, calcium and manganese in a mass ratio of 5:16:5:17:18:37:3. The bottom-modified microbial f...

Example Embodiment

[0087] Example 2

[0088] The present embodiment provides a composite water ecological restoration method, which is different from Embodiment 1 in that:

[0089] S2. Sprinkling of base improvement agents: after precipitation, sprinkle base improvement agents. The base improvement agents include soil disinfectant 55g / m3, trace element nutrient 5g / m3 and bottom modification microorganism freeze-dried powder 24g / m3.

[0090] Among them, the soil disinfectant includes a soil sterilant and a PH regulator, and the mass ratio of the soil sterilant and the PH regulator is: 1.5:2. Micronutrients include magnesium, iron, zinc, potassium, copper, calcium and manganese in a mass ratio of 7:11:10:13:22:33:5. The bottom-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] The ground-modified microorganism freeze-dried powder was added with brown ...

Example Embodiment

[0099] Example 3

[0100] The present embodiment provides a composite water ecological restoration method, which is different from Embodiment 1 in that:

[0101] S2. Sprinkling of base improvement agents: after precipitation, sprinkle base improvement agents. The base improvement agents include soil disinfectant 50g / m3, trace element nutrient 8g / m3 and bottom modification microorganism freeze-dried powder 20g / m3.

[0102] Among them, the soil disinfectant includes a soil sterilant and a PH regulator, and the mass ratio of the soil sterilant and the PH regulator is: 1:2. Micronutrients include magnesium, iron, zinc, potassium, copper, calcium and manganese in a mass ratio of 6:13:7:15:20:35:4. The bottom-modified microbial freeze-dried powder includes Bacillus subtilis, EM bacteria, photosynthetic bacteria, lactic acid bacteria and nitrifying bacteria, and the mass ratio is 33:17:24:10:16.

[0103] Ground-modified microorganism freeze-dried powder was added with brown sugar ...

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...
