Breeding tail water dam type settlement device

Abstract

The invention belongs to the technical field of sewage settlement, and discloses a breeding tail water dam type settlement device, which comprises a box body; a first conical box is installed at one end of an inner cavity of the box body, a second conical box is arranged on one side of the first conical box, a settlement box is arranged on one side of the second conical box, and sludge grooves arefixedly formed in the bottoms of inner cavities of the first conical box and the second conical box; after a water source enters the inner cavity of the first conical box, foreign matter settle intothe inner cavity of the sludge tank at the bottom due to gravity, water at the top overflows into the inner cavity of the second conical box through the through opening in the gate; similarly, the foreign matter settle in the inner cavity of the second conical box again and settle into the inner cavity of the sludge tank, and meanwhile, clean water at the top overflows into the inner cavity of thesettling tank on one side through the discharge outlet; the first conical tank and the second conical tank are connected to form dam type settling, and impurities are automatically settled at the bottom; and finally, the clean water source at the top automatically flows to the other side for next-step settling. In this way, settlement efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage sedimentation, and in particular relates to a breeding tail dam type sedimentation device. Background technique [0002] Seawater pond aquaculture is currently the most important aquaculture method in the seawater aquaculture industry in my country's coastal areas, and it is one of the important ways for people to utilize marine biological resources and develop marine aquaculture. The objects of mariculture are mainly fish, crabs, shrimps and other animals. During the breeding process, not only a large amount of toxic and harmful organic substances such as residual bait, excrement, and biological corpses will accumulate in the water body, but also a large amount of toxic and harmful inorganic substances will accumulate, such as ammonia nitrogen, hydrogen sulfide, nitrous acid, etc. Therefore, The water source needs to be treated, and the sedimentation process must be used in the treatment.

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following problems: 1. The internal structure of the existing sedimentation tank is simple, and only natural static sedimentation is used, so the efficiency is low and the sedimentation time is long; 2. The traditional sedimentation adopts longitudinal one-time sedimentation, so the sedimentation is simple and the effect of the sedimentation is high. Not good, the boundary between the precipitated impurities and the clear water at the top is not thorough, and the impurities at the bottom of the clear water layer are still relatively high
