Embodiment 1

[0122] Example 1 - Restoration of eutrophic water bodies by artificial floating islands

[0123] 1. Use bamboo poles and tree trunks to form the outer frame of the floating island unit in any shape (such as triangle, quadrangular, pentagonal, hexagonal), and use degradable fibers (such as palm rope, hemp rope, thickness less than 3mm) for the joints of the floating island unit outer frame bamboo strips) fixed.

[0124] 2. Use degradable fibers (such as palm rope, hemp rope, bamboo strips with a thickness less than 3mm) to weave into a net in the outer frame, and the degradable fiber net is connected with the outer frame.

[0125] 3. Fill the degradable fiber net with horizontally and vertically staggered reed bundles and straw bundles, with a thickness of 10cm to 100cm; first connect the reed bundles and straw bundles with reeds and straw, and then connect the reed bundles and straw bundles with the degradable fiber mesh connect.

[0126] 4. Spread 5cm to 20cm of soil on ree...

Embodiment 2

[0141] Example 2-remediation of heavy metal polluted water by captive floating plants

[0142] 1. Use bamboo poles, tree trunks, PVC pipes, floating objects, and ropes to form a floating plant growth frame of any shape.

[0143] 2. Set multiple fixed anchors and fixed piles in the water area where floating plants are expected to grow.

[0144] 3. Use ropes and iron wires to connect the growth frame of floating plants with multiple fixed anchors and fixed piles, and properly loosen the length of the connecting ropes and iron wires to adjust the water level.

[0145] 4. When the temperature is stable above 15°C, put water turtles, water spinach, and water hyacinth into the outer growth frame of floating plants.

[0146] 5. When water turtles, water spinach, and water hyacinth are covered with floating plant growth frames, 1 / 2 to 2 / 3 water turtles, water water spinach, and water hyacinth are salvaged; during the peak growing season, every 20 days to 30d to salvage once.

Embodiment 3

[0148] Example 3 - Tall fescue and bluegrass mixed cropping repair cadmium and zinc polluted soil

[0149] 1. Plow the soil polluted by cadmium and zinc before planting. The plowing depth is 20cm to 30cm. Remove bricks, stones, branches, plastics and other sundries in the soil, and rake the topsoil; when the soil is sticky , combined with plowing and adding fine sand to improve the aeration of the soil; when the soil is poor, combined with plowing, apply 500kg-1000kg of organic fertilizer or 80kg-100kg of compound fertilizer per mu.

[0150] 2. It can be sown in spring, summer and autumn in warm regions, spring sowing in April to May in alpine regions, and autumn sowing in September to October in the south of the Yangtze River.

[0151] 3. When tall fescue and bluegrass are mixed, mix 30kg-35kg of tall fescue seeds and 5kg-10kg of bluegrass seeds per mu.

[0152] 4. Before sowing, apply 2000kg-3000kg of thin manure per mu to keep the soil moist, and cover with a layer of fi...

Abstract

The invention discloses a method for biologically remediating a water body and soil comprehensively utilizing resources. The method comprises the steps: (1), determining main pollutants in a selected land area or water body area; (2), selecting to plant and/or cultivate fast-growing herbaceous plants, fast-growing alga, trees, bushes, fungi or microorganisms with high remediation efficiency in the selected land area or water body area; (3), harvesting or collecting the fast-growing herbaceous plants and the fast-growing alga after growing to reach a suitable height or size; (4), concentratedly processing the harvested or collected fast-growing herbaceous plants and the fast-growing alga, and comprehensively utilizing to prevent the pollutants from dispersing; (5), remediating an eutrophic water body by adopting an artificial floating island; (6), remediating a heavy metal polluted water body by confining floating plants; (7), repairing cadmium and zinc polluted soil by mixed-cropping festuca arundinacea and bluegrass; (8), remediating polycyclic aromatic hydrocarbons (PAHs) polluted soil by mixed-cropping alfalfa and italian ryegrass; and (9), extracting and recovering silver from silver-containing wastewater remediation plants.

Description

technical field [0001] The invention relates to a method for realizing restoration of water body, soil and comprehensive utilization of resources through biological planting and / or cultivation, harvesting and centralized treatment, and belongs to the field of environmental protection. Background technique [0002] The rapid economic development, the continuous growth of population, the sharp increase of water consumption, the corresponding increase of sewage discharge, the environmental capacity and ecological carrying capacity of the water body are overwhelmed, and the ecological system is greatly damaged. The pollution levels of the Yellow River, Huaihe River, Songhua River, Liaohe River and other waters in my country are inferior to category V, which seriously restricts the sustainable development of my country's economy. It is urgent to comprehensively control and restore water eutrophication and heavy metal pollution. [0003] Soil is one of the material bases for the s...
