Nitrogen-protecting deodorant for faeces of pig and method for producing the same

Abstract

The invention relates to waste treatment, in particular to a pig-raising manure nitrogen-preserving deodorant and a production method thereof. Sulfuric acid, hydrochloric acid, magnesium sulfate and ferrous sulfate are taken as the main raw materials for preparing the nitrogen-preserving deodorant; the process is simple, and the cost is low, thereby solving the problem of environmental pollution caused by the pig-raising manure. The ingredients of the nitrogen-preserving deodorant by concentration ratio are as follows: 2-3ml / L of concentrated sulfuric acid, 2-3ml / L of concentrated hydrochloric acid, 20-30g / L of magnesium sulfate, 100-150g / L of ferrous sulfate and water. The production method is as follows: mixed solution of dilute sulfuric acid and dilute hydrochloric acid is prepared according to the mixture ratio, magnesium sulfate heptahydrate is added into the mixed solution for stirring and dissolution, then ferrous sulfate heptahydrate is added for stirring and dissolution, water is added for setting the volume, the solution is shaken up, and a finished product is obtained by being arranged in a container. The invention has reasonable formula, good nitrogen-preserving deodorizing effect and easy implementation, thereby being applicable to the pig manure treatment of small and medium-sized pig farms or family cultivation.

Description

technical field

[0001] The invention relates to waste treatment, in particular to a pig manure nitrogen-conserving and deodorant agent and a preparation method thereof. Background technique

[0002] In recent years, with the rapid development of animal husbandry, the scale of animal husbandry has been increasing, and the problem of livestock and poultry waste pollution has become increasingly prominent. According to statistics, the number of live pigs in 2005 in the country increased by 3.2 times compared with 2000, reaching more than 840 million heads. With the improvement of people's dietary structure, my country's animal husbandry will have a greater development, and livestock and poultry manure will also increase year by year. Statistics show that the annual production of livestock and poultry manure in the country is about 1.73 billion tons, which is 2.7 times that of industrial waste. Among them, the annual excrement of the pig industry is 1.062 billion tons; the annu...

Embodiment 1

[0026] The ingredients of the nitrogen-preserving deodorant are calculated according to the concentration ratio: concentrated sulfuric acid 2ml / L, hydrochloric acid 3ml / L, magnesium sulfate 20g / L, ferrous sulfate 150g / L, and the balance is tap water.

[0027] The specific production method is as follows:

[0028] (1) Take more than 100L of open glass capacity, mark the scale at 100L, add about 70L of tap water, slowly add 200ml of concentrated sulfuric acid, stir with a glass rod while adding acid, and cool to room temperature after stirring;

[0029] (2) Slowly add 300ml of concentrated hydrochloric acid into the cooling liquid, stir with a glass rod while adding the acid, and cool to room temperature;

[0030] Make the mixed liquor of dilute sulfuric acid and dilute hydrochloric acid by above-mentioned two steps;

[0031] (3) Add magnesium sulfate heptahydrate 2kg in the mixed solution of dilute sulfuric acid and dilute hydrochloric acid, stir with glass rod, dissolve compl...

[0039] The difference from Example 1 is that the proportioning of raw materials is different (Table 1), and the preparation method is the same as in Example 1.
