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] Example 1 Preparation of sulfur elemental suspension

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

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

Embodiment 2

[0027] Example 2 Preparation of biological sulfur fertilizer of the present invention

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

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

[0030] Preparation: The above-mentioned weight percentages of the components are conventionally mixed, and the mixture is obtained by centrifugal shrinkage and stirring.

Embodiment 3

[0031] Example 3 Preparation of biological sulfur fertilizer of the present invention

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

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

[0034] Preparation: The above-mentioned weight percentages of the components are conventionally mixed, and the mixture is obtained by centrifugal shrinkage and stirring.

Abstract

The invention discloses a biological sulfur fertilizer which consists of 80 to 99 wt% of elemental sulfur suspension, 0.02 to 2 wt% of dispersant, 0.08 to 1.5 wt% of antiseptic, and 0.9 to 16.5 wt% of surfactant. The elemental sulfur in biological sulfur fertilizer is in a good suspension state under a high concentration condition, and can prevent fertilizer from greening and deterioration by inhibiting microbe growth. The biological sulfur fertilizer can increase the crop output and prevent the diseases, is an ideal elemental sulfur fertilizer, and is capable of achieving comprehensive wastewater treatment and utilization.

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, which has caused serious sulfur deficiency in the soil. Research on sulfur fertilizers in the 1990s showed that 31.5% of the soils in the 10 southern provinces are sulfur-deficient soils, and about 20% are severely sulfur-deficient soils. Soils in northern my country have also become sulfur-deficient in the past 10 years. 671 soil samples from Shanxi, Shaanxi, Qinghai and other provinces found that 30% of the soil is relatively sulfur-deficient. In plant physiology, sulfur plays an important role in the synthesis of crop proteins, oils, vitamins, and certain enzymes. Sulfur can...
