折回式全塘循环河蟹池塘养殖自净系统 设计与浅析

Design and Analysis of Self Purification System for the Whole Pond Recirculating Crab Culture

为了提升河蟹的养殖品质和减少养殖废水的排放,本文设计了一种折回式全塘流动的蟹塘养殖自净系统。通过将养殖池塘进行区隔划分,形成包括河蟹养殖区和回流净化区的塘内水体自循环流动的结构,分别进行了循环池塘的总体结构设计、增氧推水装置的设计和回流净化区入水口的设计,该系统的应用有效实现了养殖水体的循环利用。

In order to improve the quality of crab culture and reduce wastewater discharge,a self-purification system for crab pond aquaculture with air stripping and water retracing flowing around the whole pond is designed.The self-circulation structure of water in pond is formed by dividing the culture pond into two zones including crab culture area and a water purification area.Further,the overall circulating pond structure,the aerated water pushing d evice and the water inlet of the purification area are designed.The application of this system can effectively realize the cyclic utilization of aquaculture water.
