Problems solved by technology

Due to the large area occupied by garbage dumps and farms, general deodorants cannot achieve the effect at all, and the deodorization time is quite slow
At present, there is no deodorization technology specifically designed to eliminate the odor of these places. In today's society, which has higher and higher requirements on environmental quality, it is urgent to effectively and quickly deodorize these large-scale odor sources.

Embodiment 1

[0044] Embodiment 1, take by weighing 500 kilograms of weathered coal, put into reactor, add 42.5 kilograms of sodium hydroxide, 2000 kilograms of waters to react, pH value is controlled at 9~11, and reaction temperature is about 90 ℃, must not exceed 130 ℃, time After about 1 hour, put the sodium humate solution into the sedimentation tank for natural precipitation, about 3-5 days, after measuring the humic acid content meets the requirements, then pump the original solution into the downstream centrifugal spray drying tower for drying , the diameter of the drying tower is 5 meters, the tower height is 6 meters, the speed of the main engine is 7100 rpm, and the exhaust air volume is 30000m 3 , the inlet air temperature is 320-380°C, and the tail gas is evacuated by cyclone separation. After the above-mentioned drying, a black powdery or granular sodium humate product is obtained.

Embodiment 2

[0051] Embodiment 2, take by weighing 200 kilograms of peat or lignite altogether, put into reactor, add potassium hydroxide 18 kilograms, water 1000 kilograms react, process parameter control and the preparation process thereafter are the same as example 1.

[0052] Deodorization method of use: first take 1 kg of the powder or granular potassium humate deodorant obtained above and compound it into a colloidal solution according to the weight of 1:10, and then according to the weight ratio (kg) of the colloidal solution and water to 1:10, At the same time, add about 1 kg of sucrose or fructose, put it into a sealed container, and anaerobically ferment it for about 20 days at 25 ° C ~ 35 ° C until the aroma of sweet and sour wine is produced. After the water weight ratio is 1:50, it is sprayed on the garbage, and the garbage is mixed well, and the soil is rolled and compacted, which can quickly eliminate the odor and keep it for an appropriate time to achieve the eradication of ...

Embodiment 3

[0053] Embodiment 3, take by weighing 300 kilograms of lignite, pulverize, put into reactor, add 25.5 kilograms of sodium hydroxide, 1500 kilograms of waters to react, reaction solution is put into three sedimentation tanks, slag is deposited on the bottom of the tank, and solution flows into the first In the second and third pools, measure the content of sodium humate and adjust the pH value to 9-11. The resulting product is sodium humate jelly liquid, which is packaged in containers, which saves investment in expensive drying equipment.

Abstract

Said invention relates to an application of biochemical refuse deodorant used in refuse disposal plant, which uses sodium / potassium humecant, and preparation and deodorizing method thereof. The any one kind of peat, brown coal and weathered coal is used as raw material and reacted according to coal, alkali and water proportion of 100:8.5-9.5:400-500,,then deposited to obtain said deodorant. Or further more, drying the colloid solution to make the powder or granular sodium / potassium humecant deodorant. Said invention can be used by directly spraying or used in dilution form by adding cane sugar or fructose and biological fermentation, which not only can deodorize but also kill fly pupa, maggot and clarify refuse percolate.

Description

technical field [0001] The invention belongs to the technical field of biochemical products and environmental sanitation, and specifically relates to a sodium / potassium humate used as a biochemical deodorant for the deodorization of large-area odor sources such as garbage dumps, and a sodium / potassium humate deodorant Preparation and deodorizing method of use. Background technique [0002] With the increasing frequency of human production activities, various pollutions are brought, such as garbage dumps, toilets, breeding farms, slaughterhouses, etc., which will produce various odors and seriously pollute the environment. Due to the large area occupied by garbage dumps and farms, general deodorants cannot achieve the effect at all, and the deodorization time is also quite slow. At present, there is no deodorization technology specifically for deodorization in these places. In today's society, which has higher and higher requirements on environmental quality, it is urgent to...
