Aquatic excrement precipitation separation equipment

Abstract

The invention discloses aquatic excrement precipitation separation equipment. The equipment comprises a tank body, wherein the tank body is provided with a separation retaining wall for dividing the tank body into a sewage tank and a clear water tank; a filtering assembly is arranged in the separation retaining wall; the bottom of the sewage tank is inclined from two sides to the middle, and a sewage gathering groove is formed in the lowest inclined position; the clear water tank is provided with a clear water outlet capable of being opened and closed; an excrement outlet capable of being opened and closed is formed in the excrement gathering groove; and the clear water outlet is higher than the excrement outlet. According to the aquatic excrement precipitation separation equipment, a separation retaining wall with the filtering assembly is arranged to divide the tank body into the sewage tank and the clear water tank, and separation of solid dirt and sewage is achieved; the dirt gathering groove and the push-pull component are arranged to push precipitated solid dirt out of the sewage tank; and water in the clear water tank is recycled after being sterilized and disinfected, so that the utilization rate of water resources is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an equipment for sedimentation and separation of aquaculture manure, which is used for concentrating aquaculture manure and removing free water. Background technique [0002] The development of intensive high-density farming technology will play an important role in the future aquaculture industry. However, high-density breeding animals will defecate and urinate in large quantities, causing serious self-pollution and breaking the balance of the natural ecosystem in the aquaculture process. The imbalance of the ecosystem will cause conditional pathogenic bacteria to become pathogenic bacteria, and the disease resistance of aquatic animals will be reduced. more susceptible to pathogenic bacteria. A large number of water changes produce a large amount of aquaculture wastewater. The wastewater is directly discharged into rivers, rivers, lakes, seas and other natural ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned prior art has proposed a technical scheme, the scheme is provided with a plurality of sewage suction holes on the main pipeline, and the transfer of the near-end solid feces is given priority in the water. The solid feces at the far end are difficult to transfer, and it is impossible to separate feces from sewage. The treatment volume of feces is large, the contact time is long, the water body is continuously polluted, and the recycling of water resources cannot be realized; the separation of feces from water can only Reducing the oxygen consumption of manure is equivalent to increasing the dissolved oxygen in water
