Embodiment 1
[0034] Embodiment 1, the preparation of modified sodium lignosulfonate
[0035] S1 Dissolve sodium lignosulfonate in water to prepare an aqueous solution of sodium lignosulfonate with a mass percent concentration of 35%, heat it to 95°C, keep the temperature at a constant temperature for 35 minutes, then add propylenediamine, the amount of propylenediamine added is lignin 50% of the total volume of the sodium sulfonate aqueous solution, then dropwise add glutaraldehyde, the addition of the glutaraldehyde is 85% of the total volume of propylenediamine, and react at a temperature of 80°C for 2h to obtain modified lignosulfonic acid sodium solution;
[0036] S2 extracts the modified sodium lignosulfonate solution obtained in step S1 with absolute ethanol to obtain an extract, washes the extract with petroleum ether, and freeze-dries after washing. The freeze-drying conditions are:- Pre-freeze at 6°C for 2 hours, then freeze at -18°C for 18 hours at a vacuum of 0.06mPa to obtain ...
Embodiment 2
[0037] Embodiment 2, nutrient soil of the present invention
[0038] Described nutrient soil is made up of following composition and parts by weight thereof:
[0039] 35 parts of sea mud, 8 parts of peat soil, 20 parts of activated sludge, 18 parts of plant ash, 8 parts of sodium alginate, 4 parts of loosening agent, 4 parts of phoxim, 8 parts of potassium dihydrogen phosphate and 10 parts of calcium chloride; The sludge sedimentation ratio of the activated sludge is 18-22%, the sludge volume index is 90-95ml / g, and the dissolved oxygen in the effluent of the secondary sedimentation tank is 1.2-1.8mg / L; the loosening agent is composed of tripolyphosphoric acid Sodium and modified sodium lignosulfonate are composed in a mass ratio of 4:3; the modified sodium lignosulfonate is the modified sodium lignosulfonate prepared in Example 1.
[0040] The above-mentioned sea mud, peat soil, activated sludge, plant ash and loosening agent are first mixed uniformly, then sodium alginate, ...
Embodiment 3
[0041] Embodiment 3, nutrient soil of the present invention
[0042] Described nutrient soil is made up of following composition and parts by weight thereof:
[0043] 40 parts of sea mud, 10 parts of peat soil, 25 parts of activated sludge, 22 parts of plant ash, 8 parts of sodium alginate, 6 parts of loosening agent, 5 parts of phoxim, 9 parts of potassium dihydrogen phosphate and 12 parts of calcium chloride; The sludge sedimentation ratio of the activated sludge is 18-22%, the sludge volume index is 90-95ml / g, and the dissolved oxygen in the effluent of the secondary sedimentation tank is 1.2-1.8mg / L; the loosening agent is composed of tripolyphosphoric acid Sodium and modified sodium lignosulfonate are composed in a mass ratio of 5:2; the modified sodium lignosulfonate is the modified sodium lignosulfonate prepared in Example 1.
[0044] The above-mentioned sea mud, peat soil, activated sludge, plant ash and loosening agent are first mixed uniformly, then sodium alginate,...
