Abstract

The invention belongs to the field of bio-fertilizer recycling treatment, and discloses a system for multi-settlement. The system comprises a settlement device, a water inlet pipeline and a water outlet pipeline, wherein the settlement device comprises multiple settlement ponds which are sequentially connected, and a settlement opening is formed in the upper part between every two adjacent settlement ponds; the first settlement pond is communicated with the water inlet pipeline; the water outlet pipeline is connected with the last settlement pond. According to the system for the multi-settlement, disclosed by the invention, the structure is simple, the cost is low, an aqueous solution which is generated in bio-fertilizer production after waste gas is treated can be effectively settled and recycled, and environment pollution and resource waste can be avoided.

Description

technical field [0001] The invention relates to the field of biological fertilizer recovery and treatment, in particular to a system for multiple sedimentation. Background technique [0002] Biological fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization efficiency, and promoting high and stable crop yields. In the process of producing bio-fertilizer, bio-fertilizer production enterprises will produce tail gas. The components in the tail gas are relatively complex, mainly including dust, floating dust and fine bio-fertilizer particles. The main component of the gas is the gas volatilized from raw materials during the production of bio-fertilizer , the main gas components are SO 3 , SO 2 , NO 2 , NH 3 , water vapor, etc., pollute the atmosphere. Especially in cloudy and rainy days or when the air pressure drops, it often c...
