Embodiment 1

[0032] Mix the following raw materials, add water to a total weight of 100kg, and stir in a mixing tank for 10 hours before filtering, and the obtained liquid is a synergist for promoting nitrogen absorption:

[0033] 1) 10kg of organic acids, including 5kg of fulvic acid, 0.5kg each of alanine, glutamic acid, aspartic acid and phenylalanine (a total of 2kg of amino acids), 0.5g of each of deoxyribonucleic acid and ribonucleic acid (total 1kg nucleic acid), 2kg nitro humic acid;

[0034] 2) 85% industrial grade phosphoric acid 8kg (according to P 2 o 5 5kg in total)

[0035] 3) 300-500 mesh Mediterranean deep-sea brown algae powder (dry weight) 3kg;

[0036] 4) Alkyl polyglycoside surfactant 0.5kg.

Embodiment 2

[0038] Mix the following raw materials, add water to a total weight of 100kg, and stir in a mixing tank for 10 hours before filtering, and the obtained liquid is a synergist for promoting nitrogen absorption:

[0039] 1) 10kg of organic acids, including 4kg of fulvic acid, 0.5kg each of alanine, glutamic acid, aspartic acid and phenylalanine (2kg of amino acids in total), 1kg of deoxyribonucleic acid and 0.5g of ribonucleic acid (total 1.5kg nucleic acid), 1kg acetic acid and 2kg nitrohumic acid;

[0040] 2) 5.8kg of 85% industrial grade phosphoric acid, 2.7kg of potassium dihydrogen phosphate, 5kg of sodium phosphate (according to P 2 o 5 7kg in total);

[0041] 3) 300-500 mesh Mediterranean deep-sea brown algae powder (dry weight) 2kg;

[0042] 4) Alkyl polyglycoside surfactant 0.8kg.

Embodiment 3

[0044] The synergist for promoting the absorption of nitrogen obtained in Example 1 is used in the sewage treatment plant of the paper mill, added to the original urea dilution device, stirred and mixed evenly, and then added to the pH adjustment tank with a metering pump. It is 30,000 cubic meters per day, fully mixed with the pretreated wastewater, and then enters the biochemical treatment section to provide nitrogen nutrients needed for the growth of activated sludge. The original use of urea in the sewage station is about 6 packs / day, totaling 240 kg. According to the ratio of 30% of the total urea can be saved by mixing nutrition synergist and urea, it is changed to 160 kg of urea per day.

[0045] 2.4 kg of synergist.

[0046] Comparison of removal rate of major pollutants before and after adding synergist

[0047]

[0048] After nearly a month of testing, it can be seen that the use of synergists can achieve the following effects:

[0049] (1) Adding 2.4 kg of syne...

Abstract

The invention provides a synergist promoting the absorption of nitrogen, which also comprises phosphorus nutrient, deep-sea algae, alkyl polyglycoside surfactant except for one or several kinds of organic acid. The synergist can be specifically used for the environment lack of nitrogen nutrition to solve the problem of poor growth of microorganism or plants due to the lack of nitrogen nutrition. Using the synergist promoting the absorption of nitrogen provided by the invention can reduce the amount of nitrogen nutrition used significantly, thereby avoiding the waste of nitrogen and new pollution.

Description

technical field [0001] The invention relates to the field of environment, in particular to water treatment systems and soil systems requiring nitrogen supplementation, and specifically relates to a synergist for promoting nitrogen absorption. Background technique [0002] Urea is the nitrogen supplement product with the highest nitrogen content and the widest application range. After being added to nitrogen-deficient soil or water body, due to the action of urease and nitrifying bacteria, urea is rapidly decomposed, and a large amount of urea is lost through ammonia volatilization, nitrification and denitrification, and leaching. According to agricultural calculations, the seasonal utilization rate of urea nitrogen fertilizer is only about 35%, and it remains in the soil very little, causing economic losses and serious environmental pollution. After urea is applied to the soil, it is hydrolyzed into ammonium carbonate and ammonium bicarbonate under the action of urease, and...
