Abstract

The invention provides a method for producing liquid fertilizer by bamboo shoot wastewater. The method is characterized in that the raw materials include 30 to 50 parts of fresh bamboo shoot wastewater, 10 to 20 parts of inorganic fertilizers, 1 to 5 parts of natural active organic materials, 0.1 to 0.5 part of trace elements, 1 to 5 parts of botanical fungicides and 1 to 2 parts of natural surfactants. The method comprises the production process that the fresh bamboo shoot wastewater, the inorganic fertilizers, the natural active organic materials, the botanical fungicides and the natural surfactants are weighed according to the formula; after being stirred and mixed uniformly, the mixture is put into a sealed fermentation tank to be fermented at the fermentation temperature being 35 to 45 DEG C for the fermentation time being 5 to 10 days; then, the fermented mixture is filtered; filter liquor is collected; the liquid fertilizer is obtained. The method has the advantages that the bamboo shoot wastewater is changed into valuable materials from waste materials; good economic benefits and ecological benefits are realized.

Description

technical field [0001] The invention belongs to the field of fertilizer production, in particular to a method for producing liquid fertilizer from bamboo shoot wastewater. Background technique [0002] The cooking of bamboo shoots during the processing will produce a large amount of wastewater. The components of the processing wastewater contain a large amount of nutrient-rich substances such as nitrogen and phosphorus, which need to be treated before they can meet the discharge standards. The main process of wastewater treatment is hydrolysis + contact oxidation. The auxiliary buildings and facilities include grids, sedimentation tanks and regulating tanks. Wastewater directly enters the grid wells through the pipe network, and enters the regulating tanks after removing large impurities. After the water quality is regulated in the regulating tank, it is transported into the hydrolysis tank to convert the refractory macromolecular organic matter into easily degradable small ...
