Aquatic product culture waste water processing apparatus

Abstract

The invention discloses an aquatic product culture waste water processing apparatus, which comprises a three-stage settlement filter tank, a water inlet pump is arranged outside the three-stage settlement filter tank, three groups of filter layers are arranged in the three-stage settlement filter tank; culture sewage is introduced in the three-stage settlement filter tank for sedimentation and filtration through the water inlet pump, then is introduced in an oxidation absorption pool, the oxidation absorption pool is divided into a left space and a right space by a separator plate, an ecology carbon fiber filling layer is arranged in the left space, a netted support bracket and a biology active carbon filling layer are arranged at the right side, water through oxidation, absorption and filtration is introduced in a disinfection oxygenation pool through the netted support bracket; an ultraviolet ray sterilization apparatus is arranged at the inner top of the disinfection oxygenation pool, a Y-shaped aeration pipe is arranged in the disinfection oxygenation pool, and is communicated with a blower outside the disinfection oxygenation pool through an air inlet pipe. The aquatic product culture waste water processing apparatus integrates the functions of mechanical filtration, chemical filtration and biofiltration, the culture waste water is purified and processed to recyclable water resource without pollution, pollution on natural water can be effectively avoided, water source is saved, and the aquatic product culture waste water processing apparatus promotes the healthy development for the aquaculture industry.

Description

[0001] technical field [0002] The invention relates to the field of aquaculture wastewater treatment, in particular to an aquaculture wastewater treatment device. Background technique [0003] In recent years, aquaculture has developed towards intensive, high-density and high-yield farming, which has increased the density and output of aquaculture; but at the same time, a large amount of wastewater produced by intensive farming has also caused great pollution to the environment , it contains a large amount of residual bait, aquaculture biological metabolites, bacteria, organic pollutants, etc., which destroy the natural ecological balance of the water environment, degrade the water quality, and even cause the death of aquatic organisms, thus restricting the further development of the aquaculture industry. . Contents of the invention [0004] The technical problem mainly solved by the invention is to provide an aquaculture wastewater treatment device. [0005] In order ...
