Soft-shelled turtle greenhouse tail water treatment system

Abstract

The invention discloses a soft-shelled turtle greenhouse tail water treatment system, and belongs to the field of ecologic treatment of sewage. The system comprises a plurality of greenhouse tail water pools, a tail water precipitation pool, a biochemical pool and an outside pond culture pool, the tail water precipitation pool comprises a first precipitation pool and a second precipitation pool which are adjacently arranged, a water retaining wall is vertically arranged between the first precipitation pool and the second precipitation pool, the middle portion of the water retaining wall is obliquely downward uniformly provided with a plurality of overflow tubes along a water flow direction, the upper side of the water retaining wall is obliquely downward provided with an overflow surface along the water flow direction, the greenhouse tail water pools come together through a water inlet pipeline and then are connected with the first precipitation pool, a water guiding channel is arranged between the upper side of the second precipitation pool and the biochemical pool, the water guiding pipeline is provided with a water guiding pump, a water draining pipeline is arranged between the biochemical pool and the outside pond culture pool, and the water draining pipeline is provided with a water draining pump. The system has the advantages of reasonable structure design, low tail water treatment cost and good treatment effect, and can recycle greenhouse tail water to meet use demands.

Description

technical field [0001] The invention belongs to the field of sewage ecological treatment, in particular to a tail water treatment system for soft-shelled turtle greenhouses. Background technique [0002] Turtle is rich in nutrition, containing protein, fat, calcium, iron, animal glue, keratin and multivitamins. It is a rare tonic and a treasure of aquatic products. my country is the country with the largest scale of soft-shelled turtle breeding in the world. With the improvement of people's living standards in our country, domestic consumption of soft-shelled turtles is increasing day by day. High-quality aquatic products such as soft-shelled turtles are gradually going abroad and exported to Southeast Asia, Japan and other regions, which greatly promotes the development of soft-shelled turtles. The development of soft-shelled turtle farming industry. The culture mode of soft-shelled turtles in my country is mainly industrialized high-density farming of soft-shelled turtles....

AI Technical Summary

Problems solved by technology

At present, there is no set of treatment methods for the removal of pollutants in the tail water of greenhouse soft-shelled turtle farming, which are highly efficient, simple in operation and management, and suitable for popularization and application. Most of the tail water of greenhouse soft-shelled turtle farming is directly discharged without any treatment, resulting in eutrophication of surrounding water bodies It seriously affects the surrounding ecological environment and the physical and mental health of residents. Complaints occur from time to time, which seriously restricts the healthy development of the greenhouse soft-shelled turtle farming industry.

The tail water of greenhouse soft-shelled turtle culture adopts the traditional biological denitrification method, which must add carbon source, which is poor in economy and operability
