Mariculture tail water treatment system

Abstract

The invention discloses a mariculture tail water treatment system. The mariculture tail water treatment system comprises a shallow sedimentation tank, a microorganism directional conversion tank, an electroflotation treatment system and a sludge drying tank; the shallow sedimentation tank comprises a tank body and at least two rows of inclined plate filler layers which are arranged up and down; the microorganism directional conversion tank comprises a main nitrification chamber for accommodating nitrifying bacteria and a denitrification chamber for accommodating denitrifying bacteria; and the electroflotation treatment system comprises anelectroflotation generation device, an aeration deoxidation pond and a filter, the electroflotation generation device can generate electrolytic reaction to generate gas, and a slag discharge pipe of the electroflotation treatment system communicates to the sludge drying pond.According to the invention, mariculture tail water can be treated, and the environmental pollution caused by suspended matters, organic matters, ammonia nitrogen compounds and the like in the mariculture tail water is prevented.

Description

technical field [0001] The invention relates to the technical field of aquaculture tail water treatment, in particular to a marine aquaculture tail water treatment system. Background technique [0002] Mariculture is the production activity of cultivating marine aquatic economic animals and plants by using coastal shallow beach. Including shallow sea aquaculture, tidal flat aquaculture, harbor aquaculture, etc. The objects of mariculture are mainly fish, shrimps and crabs, shellfish, algae and other economic animals such as sea cucumbers. Mariculture is an important part of the aquaculture industry. [0003] Mariculture will produce mariculture tail water. Since there are a large amount of solid organic matter such as residual bait, feces and fish mucus in the mariculture tail water, the direct discharge will pollute the environment. [0004] In view of this, the inventors of the present invention devised the present invention. Contents of the invention [0005] The ob...
