Embodiment 1

[0038] Take 100ml of sulfuric acid solution in a three-necked flask, add 0.3001g of dry sheep manure sample while stirring, stir and dissolve, heat the reaction system to 80 degrees Celsius, hydrolyze for about 30 minutes, add 0.0031g of ammonium molybdophosphate catalyst and 2.5010g potassium chlorate, reaction system sulfuric acid concentration is 5moL / L, with the ClO that generates 2 Derived, using five-stage absorption (the first four stages are ice water, the fifth stage is sodium carbonate solution with a mass fraction equal to 0.05), the total reaction time is about 100min, until chlorine dioxide is no longer produced, use the five-step iodometric method Determination of the content and purity of chlorine dioxide, based on the percentage of chlorine converted into chlorine dioxide in potassium chlorate, the yield of chlorine dioxide is 44.35%, and the purity is 97.56%. After the reaction, the residual liquid is adjusted to pH with ammonia water and potassium hydroxide ,...

Embodiment 2

[0040] Take 100ml of sulfuric acid solution in a three-necked flask, add 0.4002g of sheep manure sample while stirring, stir and dissolve, heat the reaction system to 80 degrees Celsius, after hydrolysis for a period of time, add 0.0032g of ammonium molybdophosphate catalyst and 2.5003 g potassium chlorate, the reaction system sulfuric acid concentration is 5moL / L, the ClO that generates 2 Derived, using five-level absorption (the first four levels are ice water, the fifth level is sodium carbonate solution with a mass fraction equal to 0.05), the reaction time is about 100 minutes, and until chlorine dioxide is no longer produced, it is measured with sodium thiosulfate solution The content of chlorine dioxide, the chlorine dioxide yield rate is 60.35%, and the purity is 97.24%;

Embodiment 3

[0042] Take 100ml of sulfuric acid solution in a three-necked flask, add 0.5001g of sheep manure sample while stirring, stir and dissolve, heat the reaction system to 80 degrees Celsius, after hydrolysis for a period of time, add 0.0031g of ammonium molybdophosphate catalyst and 2.5001 g potassium chlorate, the reaction system sulfuric acid concentration is 5moL / L, the ClO that generates 2 Derived, using five-level absorption (the first four levels are ice water, the fifth level is sodium carbonate solution with a mass fraction equal to 0.05), the reaction time is about 100 minutes, and until chlorine dioxide is no longer produced, it is measured with sodium thiosulfate solution The content of chlorine dioxide, the chlorine dioxide yield rate is 73.60%, and the purity is 98.82%;

Abstract

The invention discloses a method for preparing a sanitizer and liquid ammonium-potassium compound fertilizer from sheep manure. The method comprises the following steps of: firstly, placing a sulfuric acid solution in a three-necked flask, adding 1-10 parts of sheep manure by weight in 500 parts of the sulfuric acid solution by weight under a stirring condition, heating a reaction system to 65-90 DEG C and implementing hydrolyzation; secondly, adding 0.001-0.1 part of ammonium phosphomolybdate hydrate and 15-35 parts of potassium chlorate by weight and leading out generated ClO2 by a conduit; thirdly, implementing absorption by water and/or an alkaline aqueous solution to obtain the sanitizer; and thirdly, treating the remaining reaction mixture by ammonia water and/or other alkaline aqueous solutions to prepare the liquid ammonium-potassium compound fertilizer, wherein the reaction time is longer than 80 minutes. Environment pollution caused by the sheep manure is eliminated through the method. Besides, the method has significance for developing featured agriculture and a deep processing industry of agricultural and sideline products, and extending an agricultural production chain.

Description

technical field [0001] The invention belongs to the technical field of environmental protection agriculture, and in particular relates to a method for preparing a disinfectant and a liquid ammonium potassium compound fertilizer from sheep dung. Background technique [0002] With the rapid development of milk and mutton sheep breeding industry, more and more farms adopt large-scale breeding, thus a large amount of sheep manure has become one of the organic waste resources that need to be solved urgently. If it is not used reasonably and effectively , not only wasted resources, but also caused pollution to the environment (pollution to water, land or air). Chlorine dioxide is currently recognized as a disinfectant with excellent performance. It can be used for the purification of wastewater in sheep farms, the disinfection of water sources, and can also be used for food processing, vegetable and fruit preservation, sanitation and epidemic prevention disinfection and sterilizat...
