Embodiment 1

[0039] The method for producing all-element liquid organic fertilizer with biomass direct combustion power generation slag water comprises the following steps:

[0040] Add 55kg of humic acid to 1000kg of biomass direct combustion power generation slag water, adjust the pH value to 7.5, and then concentrate in a low-temperature vacuum at a vacuum degree of 82.7KPa and a temperature of 45°C to obtain 280kg of a paste liquid, which is passed through a 200-mesh nylon filter Filtrate, take the filtrate, and make all-element liquid organic fertilizer;

[0041] After testing, the above-mentioned all-element liquid organic fertilizer contains the following elements required for plant growth, all in weight percentage:

[0042] Humic acid=5.0%, N=0.2%, P 2 o 5 =2.0%, K 2 O=12.0%, S+Mg+Ca=6.0%, Fe+Mn+Zn+Cu+Mo+B=3.2%.

[0043] The above-mentioned low-temperature vacuum concentration is heated by circulating water. The heat of the circulating water comes from the waste heat of the bio...

Embodiment 2

[0045] The method for producing all-element liquid organic fertilizer with biomass direct combustion power generation slag water comprises the following steps:

[0046] 1000kg of biomass direct combustion power generation slag water was concentrated in a low-temperature vacuum at a vacuum degree of 90.6KPa and a temperature of 55°C, and then 40kg of amino acids were added to adjust the pH value to 6.5 to obtain 260kg of a paste liquid, which was filtered through a 180-mesh nylon filter and taken The filtrate is used to obtain a full-element liquid organic fertilizer;

[0047] The above-mentioned low-temperature vacuum concentration is heated by circulating water. The heat of the circulating water comes from the waste heat of the biomass direct-fired power generation combustion furnace. The steam after the low-temperature vacuum concentration is cooled and recovered and used as circulating water. A total of 780kg of cooling water is recovered.

[0048] After testing, the above-...

Abstract

The invention relates to a method for producing an all-element liquid organic fertilizer by adopting slag water generated in biomass direct-combustion power generation. The method comprises the steps as follows: adding organic acid to the slag water generated in biomass direct-combustion power generation, adjusting the pH value within the range of 5-8, then performing concentration as per the mass ratio of (3-30):1, filtering, and extracting filter liquor, so as to obtain the all-element liquid organic fertilizer. According to the invention, the fertilizer is produced by taking the slag water generated in biomass direct-combustion power generation as the main raw material, so that the problem about pollution of the slag water generated in biomass direct-combustion power generation is solved, and meanwhile, the nutrient substances in the slag water generated in biomass direct-combustion power generation are fully utilized to produce the liquid organic fertilizer.

Description

technical field [0001] The invention relates to a method for treating biomass direct combustion power generation slag water, in particular to a method for producing all-element liquid organic fertilizer by using biomass direct combustion power generation slag water, which belongs to the technical field of waste recycling. Background technique [0002] At present, domestic biomass direct combustion power generation slag water treatment methods generally use sedimentation tanks, thickeners, ceramic filter brick pools and other treatment methods, and a few manufacturers also use flocculation sedimentation + inclined tube + sand filtration. Such as: biofilm method, facultative biological method and activated sludge method and so on. Facultative biological sewage treatment methods include: biological turntable method, biological filter method. According to the amount of treated water, the sewage treatment plant can be divided into steel structure and concrete structure. When the...
