Problems solved by technology

However, the above processes are mainly physical processing and are still extensive. Only the filter mud of the sulfurous acid method is used, and the orange water, alcohol waste liquid, furnace ash, sugarcane pith and carbonic acid filter mud of the sugar factory are not used. Except that orange juice can be u

Embodiment 1

[0024] Example 1: Sulfurous acid process filter mud as raw material

[0025] The process for producing humic acid organic compound fertilizer using sugar factory waste residue and wastewater of the present invention follows the following process steps:

[0026] 1. Concentration of alcohol waste liquid

[0027] The PH value of the alcohol waste liquid is 4.2-4.9, slightly acidic, the main components: sugar 1.7%, ash, organic matter and native humic acid 6.5%, N is 0.06%, PO 2 O 5 Is 0.01%, K 2 It is 0.23% and the moisture content is 91.5%. Because of its high water content and low utilization rate, it must be concentrated before use. The concentration of 80°Bx is similar to that of orange water.

[0028] Using the working principle of the electric heat pump, with the refrigerant as the carrier, the vaporized 30℃ refrigerant gas is compressed by the electric heat pump, the pressure is 1.2-1.8Mpa, the temperature is ≥108℃, and the alcohol waste liquid is heated in the condensing evap...

Embodiment 2

[0045] Example 2: Carbonic acid filter mud as raw material

[0046] The process steps are the same as in Example 1, except that in step (3), the ratio of the alkalization reaction liquid to the filter mud, furnace ash and cane pith is 1:1.3 to 1.5.

[0047] The main equipment used in the present invention is common equipment for producing compound fertilizers, such as belt conveyors, screw conveyors, bucket elevators, disc ball machines, rotary dryers, vibrating screens, mixers, alkalization reaction tanks, fans, Water pump and so on.

[0048] Product quality standard of the present invention

[0049] 1. Humic acid organic compound fertilizer produced by sulphurous acid method filter mud

[0050] 1. Product quality standards

[0051] Humic acid ≥ 18%, organic matter ≥ 45%, N ≤ 9%, P ≤ 5%, K ≤ 6%, moisture ≤ 12%, inorganic calcium, magnesium, and sulfur 3%, particle size 1-4 mm.

[0052] 2. Raw materials and costs

[0053] Orange water and alcohol concentrate 280Kg 150 yuan, sulfur...

Abstract

The invention discloses a process for producing an organic humic complex fertilizer by the waste residue and waste water of sugar mills. The process comprises the following steps: condensing waste alcohol liquid; performing an alkalization reaction; mixing, reacting and composting for fermentation; crushing, screening, mixing, and disk balling; powdering, drying, screening and packaging. The process for producing the organic humic complex fertilizer by the waste residue and the waste water of the sugar mills helps thoroughly recovers and utilizes the waste residue and the waste water of the sugar mills, solve the problem of environmental pollution caused by waste discharge and increase the economic benefit and social benefit of enterprises. The novel organic humic complex fertilizer integrates yield increase benefit, quality benefit and ecological environment benefit, has stronger market competitiveness as a substitute product of imported complex fertilizers and represents the radical direction of fertilizer development in the future.

Description

Technical field [0001] The invention relates to a process for producing humic acid organic compound fertilizer by using waste residue and wastewater from a sugar factory. Background technique [0002] The cane sugar factory produces waste residue and waste water. Waste residue includes filter mud, furnace ash, bagasse, and waste water includes orange water (waste dense) and alcohol waste liquid. These things are carbon, hydrogen, and oxygen carbohydrates, containing a lot of organic acids, nitrogen, phosphorus, potassium, and various sugars and other organic matter. They are all raw materials for making organic compound fertilizers. Due to the different production clarification processes in sugar mills, there are sulfite method and carbonic acid method, there are two different types of filter mud: the amount of sulphurous acid method filter mud accounts for about 3% of the daily squeeze, and the amount of carbon dioxide method filter mud accounts for daily About 7% of the crush. ...
