Abstract
The invention relates to a method for treating starch processing wastewater. The method comprises the following steps of carrying out standing adsorption on wastewater through D4020 macroporous adsorption resin; then filtering by using a filter cloth, and then adsorbing the wastewater by using HP-20 macroporous adsorption resin; finally carrying out centrifugal treatment to obtain treated starch processing wastewater. In the treated starch processing wastewater, the total weight of starch is reduced from 5982 mg/L to 39-66 mg/L, and the content of total sugar is reduced from 13830 mg/L to 122-154 mg/L.
Description
Technical field
The present invention relates to a kind for the treatment of process of waste water, particularly relate to a kind for the treatment of process of amylum wastewater.
Background technology
Starch, in manufacturing process, can produce a certain amount of waste water.In the waste water producing in starch enterprise, contain a large amount of starch and carbohydrate.If do not processed directly discharge, due to the existence of starch and glucide, can cause breeding and the diffusion of microorganism, affect discharge low water quality and environment.Therefore, need to reduce starch in the waste water of starch enterprise discharge and the total amount of carbohydrate.At present conventional method has method of chemical treatment, absorption method etc., but effect is all not obvious, and we need to find a kind of method that can effectively remove starch and carbohydrate in waste water.
Summary of the invention
The technical problem solving: starch and the higher problem of carbohydrate total amount in amylum wastewater.
Technical scheme: the invention discloses a kind for the treatment of process of amylum wastewater, treatment step is as follows: use the alcohol solution dipping D4020 macroporous adsorbent resin of 65wt% under (1) room temperature, the time is 6～12h; (2) get amylum wastewater, add wherein D4020 macroporous adsorbent resin, macroporous adsorbent resin add-on is the 5wt%～10wt% of waste water total amount; (3) add after D4020 macroporous adsorbent resin, standing adsorption, adsorption time is 4.5～6.5h; (4) after absorption finishes, use filter cloth to filter, the order number of filter cloth is 300 order～400 orders; (5) collect supernatant liquor, in supernatant liquor, put into HP-20 macroporous adsorbent resin again, add-on is the 4wt%～6wt% of supernatant liquor gross weight, and adsorption time is 2.5～3.5h; (6) absorption finishes rear centrifugally, and centrifugal rotational speed is 4500rpm, and the time is 15～35min; (7) obtain supernatant liquor, supernatant liquor is amylum wastewater after processing.
Use the time of alcohol solution dipping D4020 macroporous adsorbent resin to be preferably 12h; The addition of D4020 macroporous adsorbent resin is preferably the 10wt% of waste water weight; Filter and be preferably 400 orders with the order number of filter cloth; The add-on of HP-20 macroporous adsorbent resin is preferably the 6wt% of supernatant liquor weight.
Beneficial effect: the amylum wastewater that disposal methods of the present invention is crossed, in amylum wastewater, the total amount of starch is down to 39～66mg/L from 5982mg/L, and in amylum wastewater, the content of total reducing sugar is down to 122～154mg/L from 13830mg/L.
