Abstract

The invention relates to the field of high-concentration organic wastewater treatment, in particular to a preparation method of a liquid fertilizer. The preparation method of the liquid fertilizer comprises the following steps: pretreatment; adjusting waste liquid; performing multi-stage fermentation; settling and separating; preparing materials; according to the method, the nutrient solution containing the high-activity multifunctional organic acid is produced through multi-stage fermentation and directional culture of the organic waste liquid, various liquid fertilizers are prepared, and the effects of various effective components in the organic waste liquid are fully utilized. According to the preparation method, the purposes of deodorization and recycling of the organic waste liquid are achieved, and the prepared liquid fertilizer has remarkable effects of improving soil, promoting root development, enhancing photosynthesis, reducing diseases, increasing yield and improving quality.

Description

technical field [0001] The invention relates to the field of high-concentration organic wastewater treatment, in particular to a preparation method of liquid fertilizer. Background technique [0002] At present, there have been reports on the production of liquid fertilizer by fermentation of livestock and poultry manure, sewage, biogas slurry, etc., but most of them aim at deodorization and resource utilization, and have not fully utilized the various active components of organic waste liquid. effect. [0003] In view of this, aiming at the shortcomings of the above prior art, the present invention provides a high-activity multifunctional compound organic acid nutrient solution produced by using high-concentration organic waste liquid, and formulated into various liquid fertilizers. Contents of the invention [0004] (1) Technical problems to be solved [0005] The purpose of the present invention is to provide a preparation method of liquid fertilizer to solve the prob...
