Treatment system for dreg organic fertilizer fermentation waste liquid

Abstract

The invention relates to a treatment system for dreg organic fertilizer fermentation waste liquid, which comprises a fermentation tank, a deodorization mechanism, a centrifugal mechanism, a neutralization reactor, a temporary storage device and an atomization drying mechanism, the top of the fermentation tank is provided with a first motor, the first motor is downwards connected with a frame type stirrer, the bottom of the fermentation tank is communicated with a waste liquid straight pipe, a filter screen is arranged at the top of the waste liquid straight pipe, and a first electromagnetic valve is arranged in the upper end part of the waste liquid straight pipe. The whole treatment system is simple in design, a plurality of processes of fermentation, stirring, deodorization, centrifugation, neutralization, re-stirring and atomization drying are included, the processes are combined layer by layer and fed back mutually, a complete circulating type fermentation waste liquid treatment system is achieved, the actual use standard is met, the production cost is reduced, the working efficiency is improved, the using effect is better than that of a traditional mode, the device is suitable for different working conditions, and better using prospects are brought.

Description

technical field [0001] The invention relates to the field of fermentation treatment of medicinal residues, in particular to a treatment system for organic fertilizer fermentation waste liquid of medicinal residues. Background technique [0002] As pharmaceutical manufacturers pay more attention to the utilization of waste residues, more and more pharmaceutical manufacturers begin to sell medicinal residues directly to fertilizer processors at low prices in order to solve the above problems. Fertilizer processing manufacturers can use the fermentation of traditional Chinese medicine waste residues, Made into organic fertilizer, the fertilizer efficiency of this kind of organic fertilizer is much higher than that of other varieties, and the sales prospect is good; and in the process of fermentation treatment, a certain amount of fermentation wastewater will be produced, which belongs to high-concentration organic waste liquid, which is rich in protein , amino acids, vitamins, ...

Problems solved by technology

[0002] As pharmaceutical manufacturers pay more attention to the utilization of waste residues, more and more pharmaceutical manufacturers begin to sell medicinal residues directly to fertilizer processors at low prices in order to solve the above problems. Fertilizer processing manufacturers can use the fermentation of traditional Chinese medicine waste residues, Made into organic fertilizer, the fertilizer efficiency of this kind of organic fertilizer is much higher than that of other varieties, and the sales prospect is good; and in the process of fermentation treatment, a certain amount of fermentation wastewater will be produced, which belongs to high-concentration organic waste liquid, which is rich in protein , amino acids, vitamins, sugars and various trace elements, have the characteristics of high concentration, high suspended solids, high viscosity, and refractory degradation, which makes the treatment of this type of wastewater very difficult. The following problems are faced. The smell of the first wastewater has It is irritating and toxic, and it is easy to leak odor during treatment. The clear liquid of the second waste water is weakly acidic, and it will pollute the environment if it is directly discharged, and the treatment scale is small, so it is not suitable to set up a neutralization reaction pool. The third is before atomization and drying. The liquid is easy to precipitate, resulting in uneven drying liquid, which affects the drying rate. The fourth product dry powder is adhesive and inconvenient to collect. Therefore, we propose a treatment system for the waste liquid of organic fertilizer fermentation with dregs
