Example Embodiment

[0019] Example 1 Fertilizer utilization method of marigold fermentation and dehydration waste liquid of the present invention

[0020] The treatment method is introduced as an example of a batch of waste liquid with a lactic acid content of 3.28 g / L and a total amino acid content of 1.06 g / L in the waste liquid of marigold fermentation and dehydration.

[0021] (1) Measure 100ml, 200ml, 500ml, 800ml, 1000ml of marigold fermentation and dehydration waste liquid with a graduated cylinder into a beaker, neutralize with quicklime (CaO) solids to pH 7.0; repeat the neutralization three times, the average amount of quicklime The values ​​are as follows:

[0022] Table 1 Average dosage of CaO as neutralizer

[0023]

[0024] According to the above data, the volume of dehydrated marigold (ml) is taken as the abscissa, the average dosage of CaO (g) is taken as the ordinate, and the linear equation of the neutralization reaction is calculated as Y=5.4507 by drawing a trend line in Excel. g / L*X...

Example Embodiment

[0028] Example 2 Application of Fermented Nutrient Solution of Marigold Fermented Dehydration Waste Liquid in Corn Pot Experiment

[0029] Use the test corn variety "Xingnong 998", take corn seeds of the same size and the same degree of plumpness, soak them in sterile water, stir with a glass rod, and soak for two hours to cause the red coat to wash out. Sow in the pots 3-4cm above the soil surface, 4 plants per pot. When the first true leaf grows, watering with clear water is used as the control group (CK), the marigold fermented squeezed dehydrated liquid (dehydrated liquid) is watered as the comparative group, and the marigold fermented dehydrated waste liquid fertilizer nutrient solution obtained in Example 1 The two-fold dilution watering was used as the experimental group, and different groups of corn seedlings were irrigated separately, 200ml per pot, 10 pots per group, watering once every 15 days, and 2 consecutive watering.

[0030] The effects of three groups of differen...

[0033] Example 3 Application of marigold fermentation and dehydration waste liquid fertilizer nutrient solution in corn field experiment

[0034] The corn variety to be tested was "Xingnong 998". One month after sowing, a 5m×5m area was randomly selected for experiment in a 10-mu corn field with uniform growth and normal management. After the marigold fermentation and dehydration waste liquid fertilizer fertilizer nutrient solution obtained in Example 1 was diluted by 5 times, the experimental area was irrigated, and the remaining area was irrigated with clean water as the control group (CK). One month later, the effects of the two groups of different treatment methods on the plant height, stem thickness, chlorophyll and other indicators of corn were measured, and it was found that the nutrient solution of the Wanshou fermentation and dehydration waste liquid fertilizer obtained by the present invention increased by 15.12% compared with the control group. , Plant height increased...

Abstract

The invention relates to a method of utilizing wastewater of marigold fermentation and dehydration to produce fertilizers. The method comprises steps such as linear equation establishment, neutralization system amplification, and the like. The problem that the cost for treating the wastewater of marigold fermentation and dehydration is high is solved. The wastes are converted into valuable resources. The effective components of wastewater of marigold fermentation and dehydration such as lactic acid, amino acids, and the like, are fully utilized. The provided method can solve the pollution problem, effectively solves the problem that the cost for treating wastes is high, provides an efficient liquid fertilizer for local crops, and greatly increases the crop output.

Description

technical field [0001] The invention relates to a method for fertilizing waste liquid, in particular to a method for fertilizing waste liquid from fermentation and dehydration of marigolds, and belongs to the technical field of sewage treatment and environment-friendly fertilizers. Background technique [0002] Marigold is the main raw material for extracting lutein. Lutein plays a variety of important functions in the prevention and treatment of diseases in the human body. In addition to being used as a colorant, marigold lutein is widely used in food, medicine, health products, Feed and other industries. In 2016, the total national production of marigold flowers was about 2.6 million tons. Due to the broad market prospect of marigold processed products, coupled with the characteristics of low investment, high benefit and simple planting technology, marigold industry has been listed as a local agricultural pillar industry and poverty alleviation industry in many areas. ...
