Embodiment 1

[0021] The method for processing waste liquid and waste residue of banana pseudostem comprises the following steps:

[0022] 1) Raw material collection: collect waste liquid and waste residue produced by banana pseudostem processing;

[0023] 2) filtering and chopping: filtering the waste liquid and waste residue obtained in step 1), and chopping the filter residue obtained;

[0024] 3) Fermentation: Mix the chopped filter residue with the filtrate obtained in step 2) to obtain a fermented liquid, adjust the pH to 6.5-7.0, put it into a fermenter, insert the cultured mature Lactobacillus acidophilus liquid strain, insert The amount is 10% of the weight of the fermentation broth, the fermentation temperature is 35-37 ° C, then add pectinase, which is 1.5% of the weight of the fermentation broth, stir, stand still, after standing for a period of time, stir it, release the fermentation in the fermentation broth gas produced;

[0025] 4) After the fermentation is finished, the f...

Abstract

The invention discloses a banana pseudostem processing waste liquid and waste residue treatment method. The method comprises the following steps: (1) a raw material is collected, wherein waste liquid and waste residue produced in banana pseudostem processing are collected; (2) filtering and crushing are carried out, wherein the waste liquid and waste residue obtained in the step (1) are filtered, and the obtained filter residue is crushed; (3) fermentation is carried out, wherein the crushed filter residue and the filtrate obtained in the step (2) are combined, such that a fermentation liquid is obtained; the pH value is regulated to 6.5-7.0; the fermentation liquid is placed into a fermentation tank; a cultured mature lactic acid liquid strain is inoculated into the fermentation broth, and pectinase is added; the mixture is stirred and is allowed to stand; and (4) when fermentation is finished, the obtained fermentation broth is returned to the field for enhancing soil fertility. According to the invention, banana pseudostem processing waste liquid and waste residue are subjected to a biological treatment and then returned to the field, such that problems of secondary water source pollution and environment pollution caused by the waste liquid and residue are thoroughly solved. The waste can be turned into a valuable matter for a second time, and the resource can be recycled.

Description

technical field [0001] The invention relates to the technical field of waste liquid and waste residue treatment, in particular to a method for processing waste liquid and waste residue from banana pseudostem processing. Background technique [0002] Banana is one of the four famous fruits in southern my country, with an annual planting area of ​​about 200,000 hectares, mainly distributed in some southern provinces such as Guangdong, Guangxi, Fujian, Hainan, and Yunnan. Pubei County, Qinzhou is one of the largest banana production base counties in the country. It is known as the "Hometown of Bananas" in China. The county has a planting area of ​​about 10,000 hectares and an annual output of 375,000 tons of bananas. After the bananas are harvested every year, a large number of banana pseudostems, also called banana leaf sheaths, that is, banana stems (leaves and leaf sheaths) are treated as waste, left in the fields, corners or piled up next to the ditch, and allowed to rot na...
