Embodiment 1

[0026] The invention provides a method for treating pineapple straw wastewater, comprising the following steps:

[0027] S1. Proportioning raw materials according to the following parts by weight: 100 parts of fresh pineapple leaves, 30 parts of adsorbent and 0.001 part of color developer;

[0028] S2, pulverizing and squeezing the juice; first put the fresh pineapple leaves into the pulverizer for pulverization, then put the pulverized fresh pineapple leaves into the juice extractor for squeezing and dehydration, and then filter to obtain waste water and pineapple straw fiber. The waste water is placed in the waste water collection container A;

[0029] S3, fiber washing; put the pineapple straw fiber obtained in S2 into a washing machine and add clear water to wash the pineapple straw fiber, and the cleaned waste water is discharged into the waste water collection container A in S2 again;

[0030] S4, dehydration; the washed pineapple straw fiber is placed in a centrifugal ...

Embodiment 2

[0044] The invention provides a method for treating pineapple straw wastewater, comprising the following steps:

[0045] S1. Proportioning raw materials according to the following parts by weight: 300 parts of fresh pineapple leaves, 90 parts of adsorbent and 0.01 part of color developer;

[0046] S2, pulverizing and squeezing the juice; first put the fresh pineapple leaves into the pulverizer for pulverization, then put the pulverized fresh pineapple leaves into the juice extractor for squeezing and dehydration, and then filter to obtain waste water and pineapple straw fiber. The waste water is placed in the waste water collection container A;

[0047] S3, fiber washing; put the pineapple straw fiber obtained in S2 into a washing machine and add clear water to wash the pineapple straw fiber, and the cleaned waste water is discharged into the waste water collection container A in S2 again;

[0048] S4, dehydration; the washed pineapple straw fiber is placed in a centrifugal d...

Embodiment 3

[0062] The invention provides a method for treating pineapple straw wastewater, comprising the following steps:

[0063] S1. Proportioning raw materials according to the following parts by weight: 200 parts of fresh pineapple leaves, 60 parts of adsorbent and 0.02 part of color developer;

[0064] S2, pulverizing and squeezing the juice; first put the fresh pineapple leaves into the pulverizer for pulverization, then put the pulverized fresh pineapple leaves into the juice extractor for squeezing and dehydration, and then filter to obtain waste water and pineapple straw fiber. The waste water is placed in the waste water collection container A;

[0065] S3, fiber washing; put the pineapple straw fiber obtained in S2 into a washing machine and add clear water to wash the pineapple straw fiber, and the cleaned waste water is discharged into the waste water collection container A in S2 again;

[0066] S4, dehydration; the washed pineapple straw fiber is placed in a centrifugal d...

Abstract

The invention discloses a pineapple straw wastewater treatment method, and relates to the technical field of ecological environmental protection. According to the present invention, fresh pineapple leaves are subjected to crushing, juicing, fiber rinsing and pressing to obtain a liquid part, the useful biochemical components in the liquid part are adsorbed by a chromatographic column so as to provide purification effect, the water purified by the chromatographic column can be drunk or can be used for washing pineapple leaves or watering, the useful biochemical components adsorbed by the chromatographic column are subjected to desorption purification to obtain a useful biochemical raw material, the adsorbent can be reused after being activated, and the fiber part is used for other purposes,wherein the whole cycle does not discharge waste, the waste is turned into treasure, the pineapple straw resources are completely utilized, and obvious good social, economic and ecological benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of ecology and environmental protection, in particular to a method for treating pineapple straw wastewater. Background technique [0002] Pineapples are widely planted in tropical regions such as Guangdong, Guangxi, Hainan, and Taiwan. The strong demand for pineapples brings hope to farmers to increase production and income. However, pineapple stalks are largely abandoned in the field due to their low use value. Burning or discarding in the fields will pollute the environment and is one of the main sources of agricultural non-point source pollution. The moisture content of fresh pineapple leaves is more than 85%, and the straw cannot rot quickly when returned to the field, which will affect the cultivation of crops in the next season and incinerate and pollute the environment. [0003] Existing pineapple stalks are utilized by crushing and returning to the field. However, there are more than 8 tons of pine...
