Aquatic product processing sewage treatment system

Abstract

The invention discloses an aquatic product processing sewage treatment system. The system comprises a sand setting device, an oil removal and separating device, a protein separation device, a hydrolysis device, a disinfection device, a centrifugal dehydration device and a defoaming device, the deoiling and separating device and the protein separating device comprise bottom plates, filter boxes arefixedly connected to the tops of the bottom plates, and outer filter cartridges are fixedly connected between the inner walls of the filter boxes. The invention relates to the technical field of sewage treatment. Vortex rotating vanes are driven to rotate through a rotating shaft; a first water pump is started to drive a water inlet pipe to pump water; oil stains are introduced into an oil stainbox through a water outlet pipe to be collected; inner filter cartridges and sliding sleeves are matched to slide up and down on the inner surface of the outer filter cartridges, so that the oil stains in aquatic product processing sewage can be effectively removed and collected, manual collection is not needed, the working efficiency is high, the inner filter cartridge moves upwards for cleaningwhen the sewage is subjected to solid-liquid separation, the operation is convenient, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system for aquatic product processing. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is the sewage produced in daily life, which refers to the complex mixture of various forms of inorganic and organic su...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sewage treatment system for aquatic products processing, which solves the problem that the existing sewage treatment system for aquatic products processing uses a protein separator for separation, and the separation effect is poor. The efficiency is low, and when the sewage is separated from the solid and liquid, it needs to be cleaned manually
