地热温室养鳖水质改良的装置研究

根据地热温室养鳖的水质要求，研制了前置式和后置式2种型式的水质改良装置进行养殖水处理，使养殖水体经常保持在3mg/L以上的溶氧，氨、氮等有害物质的含量控制在允许范围之内，实现了除渣增氧、改良水质，促进鳖的快速生长。

Study on Improving Apparatus of Water Quality of Breeding Turtles in Geothermal Greenhouse

According to the water quality requirement as to breeding turtles in heated environment, the density of oxygen is kept to 3 mg/L or more by improving water quality of front installed and step installed in the breeding water. By all these, the content of the harmful substances could be kept, such as ammonia and nitrogen, under the permissible extent in the breeding water in order to accelerate turtles' growth. The apparatus was installed and operated by Geothermal Development Corporation in Luotian County, Hubei Province. Better economic and social effects have been obtained during the course of practice.
