Abstract

The invention provides a treatment method and a treatment system of wastewater of sweet potato vermicelli. The treatment method comprises the following steps: filtering the wastewater through a filter screen, adding organic polymeric flocculants and inorganic flocculants into filtrate, uniformly mixing to form stable floccules, and centrifuging through a horizontal type scroll discharge sedimentary centrifuge to remove insoluble substances; adding a pH regulator into the wastewater and regulating pH, maintaining the temperature, adding pentosanase, and carrying out oscillatory reaction to obtain enzymolysis liquid, and carrying out centrifugal separation to obtain starch granules; adding a protein separation agent into the wastewater, uniformly stirring and mixing and then standing, then carrying out solid-liquid separation to obtain protein agglomeration substances; carrying out enzyme deactivation on the wastewater, and filtering through a reverse osmosis treatment device to obtain concentrated liquid containing macromolecular organic matters and recyclable water. The method and the system are capable of effectively separating starch and proteins in the wastewater; the separated starch and proteins can be reused; the separated wastewater is fully used; the waste of resources is reduced; the environmental pollution is reduced; the pollution load is alleviated; the subsequent biochemical treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment method and system for sweet potato vermicelli. Background technique [0002] In traditional cuisine, sweet potato vermicelli has a long history and a broad market in our country. It is generally used for hot pot cooking, or boiled in boiling water and then eaten with raw materials (such as: hot and sour noodles), and it can also be boiled. Then fry it and eat it (such as: ants climbing a tree), and sometimes it can also be used in various cooking methods such as soup. The nutrients of sweet potato vermicelli are mainly carbohydrates, dietary fiber, protein, niacin and calcium, magnesium, iron, potassium, phosphorus, sodium and other minerals. Sweet potato vermicelli has a good taste, it can absorb the taste of various delicious soups, coupled with the sweet potato vermicelli itself is soft and smooth, more refreshing and pleasant, the variety ...
