Description
Technical field
The invention belongs to field of sewage ecological treatment, particularly relate to a kind of Trionyx sinensis Wiegmann greenhouse tail water treatment system.
Background technology
Soft-shelled turtle nourishing enriches, and containing protein, fat, calcium, ferrum, animal glue, keratin and multivitamin, is rare tonic, is the treasure of aquatic products.China is the country that breeding soft-shell turtle is largest in the world, along with our people's growth in the living standard, the high-quality aquatic products such as the domestic consumption figure to Trionyx sinensis Wiegmann is increasing, Trionyx sinensis Wiegmann are the most slowly gone abroad, area such as outlet Southeast Asia, Japan etc., has been greatly facilitated the development of breeding soft-shell turtle industry.The aquaculture model of China Trionyx sinensis Wiegmann is mainly batch production high-density breeding Trionyx sinensis Wiegmann.The features such as the profitable height of high density breeding soft-shell turtle mode, Trionyx sinensis Wiegmann are grown up soon, cultivating condition is easy to control, high-density breeding mode mainly uses totally enclosed concrete-steel greenhouse, cultivation density to reach 25-30/square metre.When water temperature is higher than 20 DEG C, Trionyx sinensis Wiegmann starts to ingest, and food ration raises with water temperature and increases.If water temperature is less than optimum temperature, Trionyx sinensis Wiegmann digestive enzyme synthesis level is low, and feed conversion rate is low；When water temperature is higher than optimum temperature, owing to Trionyx sinensis Wiegmann activity increases, also can reduce feed conversion rate.Therefore, in order in ensureing greenhouse, the good of Trionyx sinensis Wiegmann grows up, the water temperature general control in greenhouse is at 30-32 DEG C, and should keep constant as far as possible.
The main feeding of greenhouse Trionyx sinensis Wiegmann is based on high protein fish flour, and mixes the bait that the vegetable protein such as Radix Dauci Sativae, Bulbus Allii coordinates.During Trionyx sinensis Wiegmann food, feedstuff directly waste rate 10-20%, to eat the 80-90% feedstuff in Trionyx sinensis Wiegmann body, have again 60-65% nitrogen phosphorus to enter sewage after Trionyx sinensis Wiegmann converts, the nitrogen phosphorus that both amount in 70-85% feedstuff is discharged in breeding wastewater.At present, regular draining can only be relied on to realize the cleaning in greenhouse, reduce the generation of contagious disease.Greenhouse breeding soft-shell turtle industry water consumption is high, calculates by the whole nation, and more than 3,100 ten thousand tons of greenhouse breeding soft-shell turtle tail water will be had every year to enter water body.Also do not have at present a set of high for greenhouse breeding soft-shell turtle tail water contaminant removal efficiency, operation management is simple, be suitable for the processing method of popularization and application, major part breeding soft-shell turtle field, greenhouse tail water directly discharges without any process, cause surrounding body eutrophication, have a strong impact on periphery ecological environment and resident is physically and mentally healthy, complaint event happens occasionally, and seriously constrains the sound development of greenhouse breeding soft-shell turtle industry.Greenhouse breeding soft-shell turtle tail water uses the necessary additional carbon of traditional biological denitrification method, economy and poor operability.Therefore, for operating condition and the cultivation tail water water quality of breeding soft-shell turtle field, greenhouse, it is necessary to find one simply, economically and efficiently processing method.
