example 1

[0036] Example 1: Add 100Kg of the active humic acid solution in a continuously stirred reactor, then add copper sulfate 18Kg, stir until copper sulfate is completely dissolved, then add ferrous sulfate 9Kg, stir until ferrous sulfate is completely dissolved; obtain active Humic acid copper solution is used as water body bactericidal insecticide.

[0037] Since the active copper humate can complex / chelate heavy metal ions in the water body, and can also absorb harmful substances in the water body such as ammonia nitrogen, hydrogen sulfide, etc., it has a good effect on improving and regulating the water body. When it kills parasites and harmful algae in the water body, the physical and chemical indicators of the water body will not change drastically. At the same time, the active copper humate is complexed / chelated, does not cause the problem of residual copper toxicity and is significantly less irritating to aquaculture animals than copper sulfate. Therefore, the active copp...

example 2

[0042] Example 2: Add the active humic acid liquid 45Kg, copper sulfate 0.45Kg, ferrous sulfate 2.14Kg, manganese sulfate 1.60Kg, zinc sulfate 2.14Kg, boric acid 0.53Kg sequentially to the reactor continuously stirred at room temperature, stir Add 6.68Kg of diammonium phosphate until it is completely dissolved, stir until the diammonium phosphate is completely dissolved, and obtain active humic acid trace element liquid fertilizer as a fertilizer for crop growth. The results of the sampling test:

[0043] N+P 2 o 5 +K 2 O=9.7% (weight)

[0044] Trace elements (Fe, Mn, Cu, Zn, B, Mo) = 2.6% (weight)

[0045] Active humic acid = 16.8% (weight)

[0046] This active humic acid trace element liquid fertilizer is used in a certain farm, and the vegetable leaves are green and the yield is increased by about 20%. The carambola fruit is plump and sweeter, and the buyer bids higher. The farm believes that it has the expected effect of supplementing trace elements.

example 3

[0047] Example 3: Add 200Kg of the active humic acid solution to the continuously stirred reactor at room temperature, then add 14Kg of diammonium phosphate powder, stir until the diammonium phosphate powder is completely dissolved, then add 7Kg of potassium chloride powder and ammonium nitrate 40Kg, stirred until all dissolved to obtain active humic acid vegetable liquid fertilizer as fertilizer for vegetable growth. The active humic acid vegetable liquid fertilizer was diluted 800 times with clear water to spray cucumbers. Compared with spraying the same amount of nitrogen, phosphorus, and potassium fertilizers, the color of cucumbers applied with active humic acid vegetable liquid fertilizer was good, the yield increased by 15%, and the taste was also good. it is good. Carry out the same experiment on spinach, the leaves of spinach are oily green, and the yield is increased by 20%.

Abstract

The present invention relates to a method for preparing active humic acid liquor by utilizing alcohol slops of sugar mill, its product and application. The method includes the following steps: clearing alcohol slops of sugar mill, making calcium salt and other non-soluble substances in the slops be precipitated to obtain supernatant fluid, evaporating said supernatant fluid at lowest temp. to obtain concentrated liquor, adding halogen oxide into the concentrated liquor and stirring them in the reactor at room temperature and making activation to obtain the active humic acid liquor. Said invented active humic acid liquor can be directly used as accelerator for accelerating seed germination and rootage, also can be made into various fertilizes for vegetables and fruit tree.

Description

Technical field [0001] The invention relates to a wastewater treatment method, a product and its use, especially a method for treating alcohol waste from a sugar factory, the product and its use. Background technique [0002] The alcohol waste liquid from sugar factories has a large amount, dark color, and high chemical oxygen demand (COD), which is easy to emit foul odor, and direct discharge will cause serious environmental pollution. In order to solve the above problems, the Chinese invention patent application specification CN1117476A discloses a technical scheme with the patent application number: 95103709.9, entitled "Method and Application of Concentrating and Powdering Alcohol Waste Liquid from Sugarcane Sugar Factory". It proposes to use the hot flue gas of the hot blast stove or boiler as the heat source, and compress the air to rapidly atomize and dry the alcohol waste liquid in the atomization drying tower, and then use the secondary cyclone separator to collect ...
