Description

Technical Field

[0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a method for preparing a river slope ecological restoration container. Background Art

[0002] Forestry waste primarily refers to the dead branches and leaves of trees, shrubs, and herbs resulting from the natural fall of forest plants or artificial pruning, as well as discarded flowers, weeds, and other plant debris from gardens and flower beds. With the continued advancement of "eco-city" and "forest city" construction, urban greening areas are rapidly expanding, and the generation of forestry waste is also rapidly increasing.

[0003] Greening waste is essentially a biomass resource and an important carrier and source for the recycling of biomass throughout its life cycle. However, due to its low utilization rate in existing technologies, it has become one of the main sources of domestic waste, bringing a huge burden to the urban and rural ecological environment.

[0004] Currently, the primary methods for disposing forestry waste in my country are landfill or traditional incineration. Both methods require significant land use, resulting in a significant waste of land resources. These methods can also easily lead to new environmental pollution problems. Furthermore, the large amounts of mineral elements absorbed from the soil by forestry waste are lost during the incineration and landfill processes, preventing the soil from replenishing its nutrients and hindering the ecological functioning of plants. my country generates a significant amount of forestry waste daily. If not promptly and effectively handled, it will pose a new environmental problem and cause pollution.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a method for preparing a river slope ecological restoration container.

[0006] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0037] Example 1

[0038] Example 1

[0039] like Figure 1 As shown, a method for preparing a river slope ecological restoration container in one embodiment of the present invention includes the following steps:

[0040] S1: Screening: Screen the branches and leaves of forestry waste. Forestry waste includes dead branches, fallen leaves, tree and shrub clippings of trees, shrubs and herbs produced by natural forestry plant withering or artificial pruning, as well as discarded flowers and weeds in gardens and flower beds.

[0041] S2: crushing the forestry waste in step S1, and then collecting the sieved waste through a sieve with a sieve aperture of 1-4 cm to obtain forestry waste shreds with a particle size of 1-4 cm and crushed forestry waste materials, wherein the crushed forestry waste materials are obtained by crushing the forestry waste and passing it through a 1-4 cm sieve, removing leaves, flowers, and other residues other than the forestry waste shreds with a particle size of 1-4 cm;

[0042] S3: Drying: Drying the forestry waste shreds in a greenhouse or workshop by heating and drying at a drying temperature of 90° C. until the moisture content of the forestry waste shreds does not exceed 15%, preferably 12%;

[0043] S4: Preparation of a composite adhesive: Starch was modified into oxidized starch, which was then cross-linked with itaconic acid for a primary cross-linking, followed by the addition of borax for a secondary cross-linking. This successfully produced an environmentally friendly starch-based adhesive with excellent water resistance and antibacterial properties. High-amylose corn starch was then deconstructed by adding a calcium chloride solution, and an environmentally friendly and highly adhesive adhesive was added to prepare a composite adhesive.

[0044] S5: Pressing: First, the composite adhesive is mixed with water in a mixing ratio of 2:1 to prepare a mixed liquid. Then, the mixed liquid is evenly mixed with forestry waste branches and trunks. The mixture is pressed into a special mold, pressed, and then dried to prepare a preform of the ecological container.

[0045] S6: reinforcement, applying a layer of composite adhesive on the surface of the prepared ecological container blank for reinforcement, and then drying;

[0046] Among them, the surface reinforcement can not only make the surface smooth and not easy to break, but also prevent the surface of the ecological container from fuzzing, while protecting the surface, resisting friction and increasing its service life;

[0047] S7: composting, mixing the forestry waste material crushed in step S2 with water, fermentation agent, and fermentation additive, and fermenting the mixture, wherein the fermentation additive is bamboo vinegar or wood vinegar, to obtain compost raw materials, which are then dried and added to the bottom of an ecological container as ecological base fertilizer.

[0048] Specifically, during the composting process, the temperature and moisture content are monitored, and a fermentation additive dilution, i.e., a bamboo vinegar dilution, is sprayed onto the fermentation pile every 3-7 days, preferably every 5 days, for a total of 8-15 sprayings, preferably 10 sprayings. The bamboo vinegar has a pH of 2-3.2, a density of 0.9-1.5 g / ml, an organic acid content of 7-11%, and a phenolic compound content of 6-8%. The amount of bamboo vinegar dilution sprayed each time is 5 L per 100 kg of compost waste material, wherein the volume ratio of bamboo vinegar to water in the bamboo vinegar dilution is 1:1000, and the total amount is 50 ml per 100 kg of compost waste material. When the moisture content of the pile is less than 50%, water is added to the pile to raise the moisture content to 60-70%, preferably 65%.

[0049] like Figure 1 As shown, in step S2, the forestry waste is crushed to produce crushed materials with a length not exceeding 4 cm. In step S3, the drying temperature of the forestry waste shreds is 80-105° C. Specifically, the moisture content of the forestry waste shreds after drying does not exceed 15%.

[0050] like Figure 1As shown, in step S4, the weight ratio of the composite adhesive to the forestry waste branches and trunks is 30-50:60-70, wherein the added environmentally friendly and adhesive adhesives include acrylic acid, urea-formaldehyde resin, and water-based polyurethane adhesives. The urea-formaldehyde resin adhesive has waterproof and moisture-proof effects, and the urea-formaldehyde resin adhesive is a milky white liquid with a solid content of 30%, a pH between 7.0-9.0, good water resistance, bending resistance, drop resistance and wear resistance, and strong adhesion.

[0051] Acrylic adhesives are environmentally friendly and offer strong adhesion. They are colorless, transparent liquids with a solids content of 50% and a pH range of 5.0-7.0. They exhibit good curing properties, excellent weather resistance, drop resistance, and strong adhesion. Water-based polyurethane adhesives are environmentally friendly, offer strong adhesion, and are highly adaptable to various processes. They are colorless, transparent liquids with a solids content of 30% and a pH range of 7.0-9.0. They offer excellent environmental performance, compatibility, and flexibility.

[0052] like Figure 1 As shown, the pressing pressure in step S5 is 20000-40000Pa, preferably 30000Pa, the pressing time is 30-60 minutes, preferably 30min, and the drying process in step S5 is: placing the pressed material and the mold at room temperature and drying naturally. The drying process time is 24-72h, preferably 48h.

[0053] like Figure 1 As shown, the amount of the composite adhesive applied in step S6 is 0.2-0.5 g / cm 2 In step S7, the weight ratio of the crushed forestry waste material to the fermentation agent is 100:0.1-1, preferably 100:0.3-0.6, and the drying temperature of the compost raw material is 60-75°C, preferably 70°C.

[0054] The above-mentioned S7 fermentation treatment step also includes:

[0055] Step 1: Adjust the carbon-nitrogen ratio of the crushed forestry waste to 15-30;

[0056] Step 2: Add fermentation bacteria and water and mix evenly until the water content of the waste reaches 60-70%;

[0057] Step three: stacking the waste into a fermentation pile and performing a stacking fermentation treatment, wherein the temperature and moisture content of the pile are monitored during the stacking fermentation treatment, and the fermentation pile is sprayed with a fermentation additive once every 3-7 days, with the amount of the fermentation additive sprayed each time being 2.5-5 ml per 100 kg of waste, and when the moisture content of the fermentation pile is less than 50%, water is sprayed on the pile until the moisture content reaches 60-70%.

[0058] Specifically, the fermentation treatment method in step three is as follows: when the pile temperature is higher than 55°C, the pile is turned over, and the pile temperature is controlled to be lower than 75°C; when the pile temperature gradually drops to below 55°C, the pile is turned over every 5-10 days; when the pile temperature drops to 15-30°C, the pile is continued to be stacked for 10-20 days, wherein the pile is turned over every 5-10 days.

[0059] In addition, the number of times the fermentation additive is sprayed is 8-15 times, preferably 10 times. The total amount of the fermentation additive sprayed is 10-50 ml per 100 kg of waste, preferably 25-50 ml. The number of effective live bacteria in the fermentation additive exceeds 200 million / g, the pH value is 5.5-8.5, and the effective live bacteria include actinomycetes, white rot fungi, nitrogen-fixing bacteria, phosphate-solubilizing bacteria, potassium-solubilizing bacteria, and cellulolytic bacteria.

[0060] Bamboo vinegar has a pH of 2-3.2, a density of 0.9-1.5g / ml, an organic acid content of 7-11%, and a phenolic compound content of 6-8%. Wood vinegar has a pH of 2.5-3.5, a density of 0.8-2.0g / ml, an organic acid content of 7-13%, and a phenolic compound content of 8-12%. Both bamboo vinegar and wood vinegar are hydrophilic solutions with strong adsorption and penetration abilities. They can be used as plant active agents, growth promoters, fertilizer retainers, soil conditioners, and soil disinfectants. They are non-toxic, harmless, and leave no residue.

[0061] The performance test of the ecological container prepared above is as follows:

[0062] First, the dry density ρ of the ecological container is determined as follows:

[0063] Use an electronic balance to weigh the ecological container and then use a vernier caliper to measure the length, width and height of the ecological fiberboard, calculate the volume and calculate its dry density according to the following formula: ρ = m / v.

[0064] ρ—Dry density of ecological container (g / cm 3 ); m—dry mass of ecological container (g); v—volume of ecological container (cm 3 ).

[0065] Then measure the average density, average thickness, water-soaked thickness, and water absorption expansion rate of the ecological container according to the following method:

[0066] After the finished eco-container is prepared, its volume is measured and the density and mass of the organic cover are calculated. The eco-container is then completely immersed in water for 24 hours and removed. When no water drips, the wet weight of the eco-container is quickly weighed. The volume after 24 hours of immersion is also measured to calculate its water absorption expansion. The calculation formula is as follows:

[0067] Water absorption expansion rate: ω = (L-L0) / L0×100%;

[0068] ω is the thickness expansion rate of the ecological container after water absorption; L is the thickness of the ecological container after water absorption; L0 is the thickness of the ecological container before water absorption.

[0069] The water holding capacity, maximum water holding capacity, effective water retention capacity, and water absorption rate of the ecological container at different immersion times were calculated, with each treatment set up 3 times. The calculation formula is as follows:

[0070] V=(M t -M0) / t;

[0071] Q max =(M 24 -M0);

[0072] Z max =(M 24 -M0) / M0×100%;

[0073] P=P sv ×M0;

[0074] P sv =0.85Z max .

[0075] Wherein, V is the water absorption rate of the ecological container (g / h); M t is the mass of the ecological container during the soaking time th (g); M0 is the dry weight of the ecological container (g); t is the soaking time of the ecological container; Q max is the maximum water holding capacity of the ecological container (t / hm 2 );M 24 is the mass of the ecological container after immersion for 24 hours (g); Z max is the maximum water holding capacity of the ecological container (%); P sv is the effective interception rate of the ecological container (%); P is the effective interception capacity of the ecological container (t / hm 2 ).

[0076] Example 1A

[0077] In addition to the mass ratio of starch adhesive to acrylic adhesive in the composite adhesive in step S4 being 30:70; the mass ratio of composite adhesive to forestry waste in step S5 being 40:60; and the usage amount of urea-formaldehyde resin adhesive in step S6 being 0.5 g / cm 2 Other than that, the rest is the same as Example 1.

[0078] Example 1B

[0079] In addition to the mass ratio of starch adhesive to acrylic adhesive in the composite adhesive in step S4 being 40:60; the mass ratio of composite adhesive to forestry waste in step S5 being 50:50; and the usage amount of urea-formaldehyde resin adhesive in step S6 being 0.6 g / cm 2 Other than that, the rest is the same as Example 1.

[0080] The steps in the above embodiment 1 were repeated twice to obtain the test data in embodiment 2 and embodiment 3. The test results are shown in Table 1 below:

[0081] Table 1 Basic physical properties of ecological containers

[0082]

[0083] The table above shows that the average density of the eco-containers ranges from 0.2161 to 0.2398 g / cm³, which is relatively low. This means that soil covering them is less likely to cause them to compact, while maintaining a certain degree of permeability, making the eco-containers easier to use. Furthermore, the water absorption expansion rates of the eco-containers in Examples 3, 3A, and 3B are relatively low, indicating the eco-containers' good stability.

[0084] Test Example 1: Water retention performance test of ecological container

[0085] In a circular aluminum box with an inner diameter of 9 cm and a height of 5 cm, 100 g of nursery soil with the same water content and saturated with water was added. Then, ecological containers with different treatments were covered on top of the circular aluminum box. When covering, it was necessary to ensure that the ecological container completely covered the open upper end of the circular aluminum box. The mass of the soil in the aluminum box was recorded every 24 hours under natural conditions indoors and at an ambient temperature of 25°C. The soil was weighed continuously for 15 days, and each treatment was repeated 3 times. The water loss of the moist soil in the ecological container made with different adhesives and different adhesive ratios was observed. The water retention effect of different types of organic covering boards was reflected by the change in water loss. The measurement results are shown in Table 2 below:

[0086] Table 215-day total evaporation water quality test results

[0087]

[0088] The test results in the table above demonstrate that the eco-containers possess a certain water retention capacity. Over 15 days of evaporation, Examples 1, 1A, and 1B lost 15.3g-16.1g of water; Examples 2, 2A, and 2B lost 15.8g-16.3g of water; and Examples 3, 3A, and 3B lost 14.5g-15.9g of water. This indicates that increasing the amount of glue applied reduces the pores in the eco-containers, gradually reducing the rate of water loss. Compared to Examples 1, 1A, and 1B and Examples 2, 2A, and 2B, Example 3B exhibits the lowest water loss, significantly reducing the amount of water evaporated and demonstrating improved soil water retention.

[0089] Test Example 2: Water Permeability Test of Ecological Container

[0090] First, place the eco-container flat on a transparent container and evenly pour 20mL of water onto the surface of the eco-container. Then, observe the time it takes from the moment the water contacts the surface of the eco-container to the moment water drips onto the bottom of the eco-container. The measurement results are shown in Table 3:

[0091] Table 3 Water permeability schedule of ecological container

[0092]

[0093] The table above shows that the permeability time of the eco-containers is consistently under 4 seconds, significantly impacting rainwater penetration. This is primarily due to the fact that increased adhesive content fills the pores in the eco-containers, reducing the number of permeable pores and increasing the time required for water to penetrate. Example 3 had the shortest permeability time, allowing rainwater to penetrate the soil under rainfall conditions, effectively reducing significant surface runoff.

[0094] Test Example 3: Water holding capacity test of ecological container

[0095] Bake the prepared eco-container in an oven at 80 degrees Celsius for 1 hour, then immerse it completely in water and measure its weight change regularly. Measure the wet weight of the eco-container after absorbing water at the following times (0.25h, 0.5h, 1h, 2h, 4h, 6h, 8h, 10h, 12h, 24h). After each removal, let it stand until no water drips from the eco-container. Quickly weigh its wet weight and record it. Then calculate the water holding capacity, maximum water holding capacity, effective interception capacity and water absorption rate of the eco-container at different immersion times, and set 3 times for each treatment. The measurement results are shown in Table 4 below:

[0096] Table 4 Water holding performance test table of ecological container

[0097]

[0098]

[0099] From the table above, we can see that as the amount of glue applied increases, the maximum water holding capacity, maximum water holding rate and effective interception rate of the ecological container decrease. The maximum water holding capacity of the ecological container of Example 1, Example 2 and Example 3 is 143.8t / hm 2 ~151.43t / hm 2 The maximum water holding rate is between 130.12% and 146.31%, and the effective storage capacity is 128.38t / hm 2 ~135.11t / hm 2 The effective interception rate is between 122.23% and 128.72%; the maximum water holding capacity of the ecological container of Example 1A, Example 2A, and Example 3A is 137.6t / hm 2 ~140.87t / hm 2 The maximum water holding rate is between 131.22% and 133.95%, and the effective storage capacity is 122.65t / hm 2 ~125.92t / hm 2 The effective interception rate is between 116.96% and 119.74%; the maximum water holding capacity of the ecological container of Example 1B, Example 2B, and Example 3B is 128.47t / hm 2 ~134.27t / hm 2 The maximum water holding rate is between 113.2% and 124.78%, and the effective storage capacity is 117.38t / hm 2 ~132.59t / hm 2 The effective interception rate is between 109.2% and 114.13%.

[0100] Specifically, compared with Examples 1, 1A, 1B and Examples 2, 2A, 3B, and Examples 3A, 3B, Example 3 has better water holding capacity and effective interception effect, so the ecological container has good water holding capacity and can effectively intercept a certain amount of rainwater in a heavy rainfall environment, thereby reducing the problem of soil erosion on exposed soil in the city and playing a role in soil and water conservation.
