Problems solved by technology

[0007] Compared with traditional elemental sulfur, the particle structure of elemental sulfur produced by biological desulfurization technology has better hydrophilicity and is not easy to block equipment pipelines. However, its biggest disadvantage is that it is easy to precipitate and change odor when placed in aqueous solution

Embodiment 1

[0024] The preparation of embodiment 1 sulfur simple substance suspension

[0025] The biogas gas containing hydrogen sulfide is absorbed by the lye through the absorption tower, and then absorbed by Thiobacillus ferrooxidans in the reactor and converted into sulfur element, the suspension containing sulfur element is pumped into the storage tank and stored as a product, and the resulting sulfur-containing The elemental sulfur content in the elemental suspension product is 5-9wt%.

[0026] Process flow: biogas → absorption tower (pH=8) → reactor (35°C) → precipitator

Embodiment 2

[0027] Embodiment 2 The preparation of biological sulfur fertilizer of the present invention

[0028] The formula of biological sulfur fertilizer of the present invention:

[0029] 80wt% sulfur suspension (prepared in Example 1), 2wt% xanthan gum, 1.5wt% sodium hydroxymethylglycinate (K99), 16.5wt% Tween 80.

[0030] Preparation: The components in the above weight percentages are conventionally mixed, and the mixture is centrifuged to shrink and stirred.

Embodiment 3

[0031] Embodiment 3 The preparation of biological sulfur fertilizer of the present invention

[0032] The formula of biological sulfur fertilizer of the present invention:

[0033] 99wt% sulfur suspension (prepared in Example 1), 0.02wt% xanthan gum, 0.08wt% sodium hydroxymethylglycinate (K99), 0.9wt% Tween 80.

[0034] Preparation: The components in the above weight percentages are conventionally mixed, and the mixture is centrifuged to shrink and stirred.

Abstract

The invention discloses a biological sulfur fertilizer, which comprises 80-99wt% sulfur elemental suspension, 0.02-2wt% dispersant, 0.08-1.5wt% preservative and 0.9% ‑16.5 wt % surfactant. The biological sulfur fertilizer of the present invention can make the sulfur element in a good suspension state at a relatively high concentration, and can prevent the microorganisms therein from making the product turn green and smelly, increase the yield of crops and greatly prevent and control diseases. An ideal elemental sulfur fertilizer realizes the comprehensive treatment and utilization of waste water.

Description

technical field [0001] The invention relates to the technical field of sulfur-containing fertilizers, in particular to a biological sulfur fertilizer and a preparation method thereof. Background technique [0002] In recent years, due to my country's agricultural fertilization habits, more attention has been paid to nitrogen, phosphorus and potassium fertilizers, and sulfur fertilizers have been neglected, resulting in serious sulfur deficiency in the soil. The research work on sulfur fertilizer in the 1990s showed that 31.5% of the soil in 10 southern provinces is sulfur-deficient soil, and about 20% of the soil is seriously deficient in sulfur. The soil in northern my country has also begun to lack sulfur in the past 10 years. , Shanxi, Shaanxi, Qinghai and other provinces measured 671 soil samples, and found that 30% of the soil was relatively deficient in sulfur. In plant physiology, sulfur plays an important role in the synthesis of crop protein, oil, vitamins and certa...
