Problems solved by technology

[0002] In the treatment of garbage, human, poultry and livestock manure, people often use the form of compost to let it ferment naturally, and the concentration of stench and peculiar smell will gradually spread to the space with the increase of fermentation days. Not only the time will be as long as 1-4 months, but also Serious secondary pollution
[0003] There are also chemical substances to achieve the purpose of deodorization through chemical reactions, but the cost is relatively high. Recently, microorganisms have been used to eliminate odors through aerobic fermentation and achieved ideal results. The odorous gases generated during the fermentation process are passed through photocatalysts. Clean air is obtained after deodorization and sterilization equipment, but the cultivation of microorganisms requires certain facilities and costs
[0004] All of these are just to achieve the elimination of bad smell from garbage, human and poultry manure, but how to overcome the problem of too fast fertilizer dissolution and insufficient plant absorption, how to reduce the loss with the soil due to leaching or surface runoff, and how to weaken the fertilizer in the soil. The chemical and biological fixation reactions carried out, how to overcome the nitrogen loss caused by the volatilization of ammonia or the denitration process after nitrification, and how to improve the stress resistance of crops, improve the utilization rate of phosphorus, and improve the photosynthesis efficiency of crops, etc. worthy of study

Embodiment 1

[0017] Put 50 liters of sulfuric acid with a concentration of 60% and 15 kilograms of 200-mesh silicon dioxide in a plastic container, start stirring, adjust the pH value to 2.5 with NaOH, apply a voltage of 100 volts, and apply a current of 450 mA for 2.5 minutes, and measure the pH value to 2.46 After turning off the power and stirring for 15 minutes, the stirring was stopped in the form of a sol. The measured concentration of silica colloid was: 30%, the diameter of silica particles was 8nm, the specific gravity was 1.10, the pH value was 2.46, and the kinematic viscosity was 20°C≤10 ×10 -2 m 2 / s.

[0018] Use 1.5 kg of the above-mentioned acidic silica sol, put it in one ton of sterilized garbage, human and poultry manure, mix it, heat it to 48 degrees, and stir it in an appropriate amount. After 4 hours, the odor is basically eliminated, and the deodorant Flavorful organic fertilizer.

Embodiment 2

[0020] Put 150 liters of sulfuric acid with a concentration of 50% and 25 kilograms of 300-mesh silicon dioxide in a plastic container, start stirring, adjust the pH value to 4 with NaOH, apply a voltage of 100 volts, and energize a current of 450 mA for 5 minutes, and measure the pH value to 3.5 , cut off the power supply, stirred for 15 minutes, and stopped stirring in the form of a sol. The measured silicon dioxide concentration was 20%, and the silicon dioxide particle diameter was 10nm. The specific gravity is 1.1, the pH value is 3, and the kinematic viscosity is 20℃≤10×0 -2 m 2 / s.

[0021] Put 1.3 kg of the above-mentioned acidic silica sol in one ton of sterilized garbage, human and poultry manure, mix and then heat to 50 degrees and stir in an appropriate amount. After 4.5 hours, the odor is basically eliminated, and an organic Fat.

Embodiment 3

[0023] Put 50 liters of sulfuric acid with a concentration of 62% and 12 kilograms of 500-mesh silicon dioxide in a plastic container, start stirring, adjust the pH value to 2.5 with NaOH, apply a voltage of 100 volts, and apply a current of 450 mA for 4 minutes to measure the pH value of 2.2 , cut off the power supply, and after stirring for 15 minutes, it was in the form of a sol and stopped stirring. The measured concentration of the colloidal dioxide was: 23%, and the diameter of the silicon dioxide particles was 6nm. The specific gravity is 1.10, the pH value is 2.2, and the kinematic viscosity is 20℃≤10×10 -2 m 2 / s.

[0024] Put 1 kg of the above-mentioned acidic silica sol into one ton of sterilized garbage, human and poultry feces, mix and heat to 60 degrees and stir in an appropriate amount. After 4.5 hours, the odor is basically eliminated, and no peculiar smell is obtained. Organic Fertilizer.

Abstract

The present invention discloses one kind of acid silica sol and is especially one kind of acid silica sol applied in treating human and animal excrement and garbage. The acid silica sol has concentration of 25-35 wt%, SiO2 grain diameter of 1-12 nm and pH 2-4, and may be used to replace microbe in treating human and animal excrement and garbage to eliminate offensive odor and to produce efficient organic fertilizer. The organic fertilizer is superior to available fertilizer in that it will be dissolved slowly for plant to absorb fully and has slow releasing, water maintaining and silicon replenishing functions.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an acidic silica sol used for treating garbage and preparing organic fertilizers. Background technique [0002] In the treatment of garbage, human, poultry and livestock manure, people often use the form of compost to let it ferment naturally, and the concentration of stench and peculiar smell will gradually spread to the space with the increase of fermentation days. Not only the time will be as long as 1-4 months, but also Secondary pollution is serious. [0003] There are also chemical substances to achieve the purpose of deodorization through chemical reactions, but the cost is relatively high. Recently, microorganisms have been used to eliminate odors through aerobic fermentation and achieved ideal results. The odorous gases generated during the fermentation process are passed through photocatalysts. Clean air is obtained after deodorization and sterilization equipmen...
