Problems solved by technology

[0002] Food waste composting technology is a relatively common treatment method, but food waste contains a large amount of waste oil, which is easy to form a coating on the surface of soil particles, resulting in strong hydrophobicity of the soil and poor air permeability, resulting in plant root rot , in the prior art, the means of solid-liquid separation is often adopted to remove the waste oil in the kitchen waste, but the waste oil is not further processed and utilized, resulting in a waste of resources. In addition, the fertilizer produced by the kitchen waste is not durable. In a short period of time, a large amount of fertility and heat can be released, which can easily cause root burn
[0003] The patent application number is CN201310545970.5, which adopts the classification method to separate the organic matter in the kitchen waste, and ferment it to prepare the liquid organic fertilizer. This method is simple to operate and has fewer processes, but the separated organic matter contains A large amount of waste oil, it is difficult for microorganisms to decompose and utilize the oil, and the oil is coated on the soil or plant roots, which makes it difficult for plants to absorb nutrients and root rot
The patent with the application number CN201410419088.0 adopts the method of solid-liquid separation to make full use of kitchen waste, and the organic fertilizer produced can retain water and breathe freely, and has a certain slow-release effect. However, this method has high equipment costs and is difficult to produce. Realize large-scale production applications

Embodiment 1

[0029] Step 1: Heat the kitchen waste to 100°C, stir continuously until no bubbles are generated, filter the kitchen waste oil and solid residue, add 5% concentrated H2O with a mass fraction of 75% to the kitchen waste oil 2 SO 4 and 20% sodium dodecylbenzenesulfonate, react until the oil and water layers are completely separated, remove the liquid in the water layer, and obtain crude oil;

[0030] Step 2: Add 3% H to the crude oil extracted in Step 1 2 o 2 and 3.5% activated clay, stirred at 60°C for 20 minutes to obtain decolorized oil;

[0031] Step 3: Add NaOH to the decolorized oil in Step 2, stir and saponify for 2 hours, until the pH is stable at 7.5, then add 10% NaCl to obtain soap gum;

[0032] Step 4: At 40°C, uniformly mix the soap gum in Step 3 with 0.5% methyl ethyl ketone peroxide and 13% polyacrylic acid, let it settle for 1 day, solidify, press, and dry to obtain the environmentally friendly soap;

[0033] Step 5: According to the weight ratio of 1.5:1:0.8...

Embodiment 2

[0036] The operation is the same as in Example 1, wherein the heating temperature in step 1: 105°C, concentrated H 2 SO 4 Dosage and mass fraction: 7%, 80%, surfactant: 25%, sodium cetyl sulfate; H in step two 2 o 2 : 3.5%, activated clay: 5%, stirring: 65 ℃, 25min; lye in step 3: Na 2 CO 3 , saponification: 2.5h, PH: 7.6, NaCl: 15%; temperature in step 4: 45°C, hardener: 1.25%, cyclohexanone peroxide, viscous agent: 15%, methyl hydroxyethyl cellulose, Precipitation: 1.5 days; Municipal garbage in step five: pericarp, weight ratio of each component of substrate: 2:1.5:1, mesh number: 55; The parts by weight of each component of slow-release agent in step six: 17,14,27, 46; dosage of sustained release agent: 13%, YM bacteria: 2%, temperature: 85°C, fermentation: 5 days.

Embodiment 3

[0038] The operation is the same as in Example 1, wherein the heating temperature in step 1: 110°C, concentrated H 2 SO 4 Dosage and mass fraction: 10%, 85%, surfactant: 30%, fatty alcohol polyoxyethylene ether sodium sulfate; in step 2, H 2 o 2 : 4%, activated clay: 6.5%, stirring: 70°C, 30min; step 3 in lye: KOH, saponification: 3h, PH: 7.8, NaCl: 30%; step 4 in temperature: 50°C, hardener: 1.25 %, cyclohexanone peroxide, viscous agent: 17%, associative polyurethane, precipitation: 2 days; urban garbage in step 5: waste paper, weight ratio of each component of the substrate: 2.5:2:1.2, mesh number : 80; in step 6, the parts by weight of the components of the slow-release agent: 23, 15, 30, 50; the dosage of the slow-release agent: 15%, YM bacteria: 3%, temperature: 90° C., fermentation: 6 days.

Abstract

The invention discloses a method of producing environment-friendly soap and slow release fertilizer by means of kitchen waste. The method comprises the following steps: S1, carrying out solid-liquid separation and layering oil and water; S2, carrying out decoloring; S3, adding alkaline liquor to saponify; S4, uniformly mixing soap glue with a hardener and an adhesive, and carrying out precipitating, condensing, pressing and drying to obtain the environment-friendly soap; S5, crushing solid residues, urban waste and plant ash; and S6, adding 1-3% of YM bacteria and 11-15% of a slow release agent into a fertilizer primer to ferment for 4-6 days to obtain the slow release fertilizer. The slow release agent is composed of isobutylidene biurea, dicyandiamide, cyanogen quinone and ammonium polyphosphate. The method achieves recycled, efficient and energy-saving utilization of kitchen waste, and the produced environment-friendly soap is high in emulsifying capacity and excellent in decontaminating effect, and the produced slow release fertilizer can provide nutrients to plants for a long time, and is good in ventilating property and water retaining capacity.
