Description

Technical Field

[0001] The utility model relates to the technical field of melon and fruit sewage treatment, in particular to melon and fruit sewage treatment equipment. Background Art

[0002] As an important food ingredient, fruits are widely used in our daily diet. However, many people may overlook an important link, that is, the wastewater generated during the washing process of fruits and vegetables. These wastewaters contain a large amount of impurities and pollutants. If they are not properly treated, they will pose a potential threat to the environment and health. Therefore, the treatment process of fruit and vegetable washing wastewater is particularly important. First of all, let us understand the composition of fruit and vegetable washing wastewater. In the process of fruit and vegetable washing, the wastewater mainly contains sand, pesticide residues, microorganisms, organic matter and heavy metals, etc. These components are potentially harmful to the environment and human health. There are several main processes to choose from for the treatment of fruit and vegetable washing wastewater. A commonly used method is physical treatment, which is to remove solid particles and suspended matter in wastewater by filtering and sedimentation. This process usually includes steps such as coarse screening, fine screening and sedimentation. Through the use of screens of different sizes and sedimentation tanks, most of the solid particles and suspended matter are effectively removed, thereby purifying the wastewater. In addition, chemical treatment is also a common method. This method mainly uses chemical reagents to treat wastewater to remove pollutants. For example, chemical reagents such as ferric chloride can be used to coagulate and precipitate organic matter and heavy metal ions in wastewater. In addition, adsorbents such as activated carbon can be used to adsorb pesticide residues in wastewater, thereby further purifying the wastewater.

[0003] The existing fruit and vegetable sewage treatment equipment has a relatively single function, and filtering and discharging of sand and gravel, removing pesticide residues, and filtering and removing heavy metals requires multiple devices, which is troublesome and wastes a lot of space. Therefore, a fruit and vegetable sewage treatment equipment is proposed to address the above problems. Utility Model Content
