Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a treatment device for high-concentration starch wastewater. Background Technology

[0002] Starch wastewater mainly originates from the starch processing of raw materials such as corn, encompassing multiple technological stages including washing, filtration, and concentration. This type of wastewater contains a large amount of dissolved organic pollutants, including proteins, sugars, carbohydrates, fats, and amino acids, as well as inorganic compounds containing nitrogen and phosphorus, and a certain amount of volatile phenols and ash. It is classified as high-concentration organic wastewater with relatively good biodegradability. Improper treatment and direct discharge will not only cause serious water pollution but also lead to resource waste. In the treatment of high-concentration starch wastewater, sedimentation tanks are one of the commonly used treatment devices. By adding flocculants and other agents to the wastewater, the pollutants in the wastewater form flocs and precipitate, thereby achieving solid-liquid separation and purifying the wastewater.

[0003] A search revealed that Chinese patent application number CN202211238360.6 discloses a treatment device for high-concentration starch wastewater. This device achieves ammoniation treatment of starch wastewater by controlling the reaction environment and incorporates a permeate reflux system to reduce ammonia nitrogen concentration and mitigate its inhibitory effect on the reaction. It is also equipped with auxiliary devices such as heating and stirring to ensure operational efficiency. However, this patent and existing similar treatment devices generally suffer from a fixed dosing point when adding flocculants and other agents to the sedimentation tank. The agents mainly rely on natural diffusion and slow water flow within the sedimentation tank for mixing, resulting in uneven distribution of the agents in the wastewater. This leads to situations where some areas have excessive agents and others insufficient agents, thus affecting floc formation, reducing wastewater treatment efficiency and effluent quality, and failing to meet the actual needs for efficient purification of high-concentration starch wastewater.

An inclined plate 687 is rotatably connected to the outer side of the lifting plate 686. A rotating block 688 is fixedly connected to the lower side of the turntable 667. The inclined plate 687 and the rotating block 688 are rotatably connected. The lifting plate 686 and the fixed cover 689 are slidably connected.

[0047] During chemical dosing, the turntable 667 drives the vertical plate 681 to rotate, facilitating the initial stirring of the wastewater by the vertical plate 681.
