Sewage treatment device for aquatic product processing

Abstract

The invention discloses a sewage treatment device for aquatic product processing, wherein the sewage treatment device includes a water inlet pipe and a water outlet pipe; one end of the water inlet pipe is penetrated into a sewage discharge tank, one side of the sewage discharge tank is provided with a grating machine, one end of the grating machine is penetrated into the interior of the sewage discharge tank, one end of the sewage discharge tank is provided with an anaerobic tank, and the sewage discharge tank is fixedly connected with the anaerobic tank through a water pump and a water guidepipe; one side of the anaerobic tank is provided with a feeding machine; the feeding machine is fixedly connected with a feeding plate through a feeding pipe, and the feeding plate is penetrated intothe interior of the anaerobic tank; one end of the anaerobic tank is provided with a flocculation tank, the top of the flocculation tank is provided with an aerator, and the bottom of the aerator isprovided with a gas-guide pipe; the gas-guide pipe is penetrated into the interior of the flocculation tank; one end of the flocculation tank is provided with a sedimentation tank, and the bottom of the flocculation tank and the bottom of the sedimentation tank are fixedly connected with a pump through a sewage-guide pipe; the other end of the pump is provided with a sewage discharge pipe. Sewagecan reach the discharge standard through hierarchical decontamination, the overall structure is simple, the cost is low, the practicability is high, and the promotion is easy.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sewage treatment device for aquatic product processing. Background technique [0002] Aquatic product processing includes the food processing industry that uses the edible parts of fish, shrimp, crab, shellfish, algae, etc. to make frozen products, pickled products, dried products, canned products and cooked foods, etc. A non-food processing industry that uses aquatic animals and plants and food processing waste as raw materials to process fish meal, fish oil, cod liver oil, hydrolyzed protein, isinglass, alginate, iodine, and chitin. During aquatic product processing, aquatic products need to be cleaned, cut and other processes. During this process, sewage will be generated. The sewage often contains animal blood, bones, dander or grease, etc., and aquatic products generally have a fishy smell. Direct discharge of sewage is not only easy to pollute the envi...
