Description

Multistage flocculation charge device of coffee bean fermentation sewage

Technical Field

Background

After the coffee fruits are picked, the coffee fruits are subjected to primary processing such as enzymolysis or fermentation, drying and the like to form the commodity beans. The primary processing of the coffee fruit mainly comprises 3 modes of wet processing, dry processing and semi-dry processing. More than 80% of the primary processing of Yunnan province interior coffee fruits is processed by a wet method.

The water consumption of wet processing is large, the generated wastewater is strongly acidic, is rich in a large amount of suspended non-oily organic matters and nitrogen and phosphorus nutrient substances, has high toxicity, and can cause eutrophication of a water body and death of aquatic organisms when directly discharged into a river.

In the prior art, reagents such as flocculating agents, coagulants and the like are required to be added before the coffee primary processing wastewater is treated so as to separate out micro and dispersed suspended matters contained in the wastewater as solid floccules, thereby facilitating the subsequent solid-liquid separation. Only primary filtration is carried out before the existing dosing, the content of suspended matters still reaches 260mg/L, the dosing amount is increased due to direct dosing, and the influence of sewage treatment cost is increased.

Floc generated by the water body after adding the medicine is called alum blossom, is in a suspended state in the water and is difficult to settle, and the alum blossom is brought to the water surface by utilizing bubbles above the alum blossom through the subsequent ventilation air floatation step to form scum and then is scraped out. However, because the content of suspended matters is too large, the existing vent pipe is easy to generate aeration bubbles to influence the volume of bubbles, and the air floatation removal effect of flocs is reduced due to the alum flocs carried by the overlarge volume of the bubbles.
