Embodiment 1
[0027] Example 1 The main components of the waste liquid from boric acid production are: 4.8% boric acid, 0.4% sulfuric acid, and 24.1% magnesium sulfate.
[0028] Calculated on the basis of every hundred kilograms of compound boron fertilizers produced, 300kg of boric acid waste liquid is neutralized to pH6 with 4kg of lightly burned magnesium powder, press-filtered after neutralization, and the filtrate is concentrated to 240kg at 100-110°C, and the concentrated solution is set aside; Add 1.1kg of iron filings, 0.5 kg of zinc oxide and 30kg of concentrate in the kettle, add 1.4kg of sulfuric acid dropwise at room temperature until the iron filings and zinc oxide are fully reacted and completely dissolved, the reaction solution is sent to a crystallizer, add 210kg of concentrate, and Crystallize below 25°C, centrifuge after crystallization, and dry the obtained crystals at 60-70°C to obtain semi-finished products. After inspection, the boron content is 0.62, and 3.3 kg of bor...
Embodiment 2
[0030] The composition of embodiment 2 boric acid waste liquid is: boric acid 4%, sulfuric acid '0.4%, magnesium sulfate 25.6%, according to
[0031] The method of embodiment 1 changes proportioning, prepares active ingredient: boron 1%, magnesium>7%, zinc 0.2%, the compound boron fertilizer of iron 0.6%.
[0032] Boric acid waste liquid 300kg, light burnt magnesium 4kg neutralize and concentrate to 160kg, iron-zinc mixture: iron filings 0.7kg zinc oxide 0.3kg concentrate 30kg sulfuric acid 0.8kg crystallizer add concentrate 130kg.
[0033] The boron content of the prepared semi-finished product is 0.4%, and 3.4kg of boric acid is added. The measured active ingredients are: boron 1.02%, magnesium 7.8%, zinc 0.21%, iron 0.59%.
Embodiment 3
[0034] The composition of embodiment 3 boric acid waste liquid is: boric acid 5%, sulfuric acid '0.2%, magnesium sulfate 27.6%, change proportioning according to the method for embodiment 1, and preparation active ingredient is: boron 1.2%, magnesium>7%, zinc 0.1%, iron 0.4% compound boron fertilizer.
[0035] Boric acid waste liquid 300kg, lightly burned magnesium 2kg neutralized and concentrated to 160kg, iron-zinc mixture: iron filings 0.46kg
[0036] Zinc oxide 0.15kg concentrate 30kg sulfuric acid 0.48kg Add concentrate 130kg to the crystallizer.
[0037] The boron content of the prepared semi-finished product is 0.48%, and 4kg of boric acid is added. The measured active ingredients are: boron 1.2%, magnesium 7.9%, zinc 0.21%, iron 0.59%.
