摘要
池塘养殖在我国水产养殖产业地位举足轻重,是保障我国优质动物蛋白供给、促进农业增效及农民增收的关键一环。随着社会经济高速发展,传统的、粗放式的池塘养殖模式凸显出一系列问题,对该产业的改良升级提出要求与挑战。以湖北省某集中连片2050亩养殖池塘为例,梳理了进排水分离改造和尾水治理的设计思路,通过新建沟渠和功能划分实现项目区进排水分离,解决了上游尾水排放对下游池塘用水的污染,降低养殖塘鱼害传染风险和灾害。同时以生态沟渠和藕塘湿地为主要净化单元,养殖尾水经处理后COD_(Mn)、总氮和总磷指标稳定达到《淡水池塘养殖水排放要求》(SC/T 9101-2007)二级标准,极大程度上避免养殖尾水对汉江水体水质与水环境的影响。同时本文对该类池塘进排水分离及尾水治理未来的设计、施工方向进行了展望,并提出一种适合湖北省养殖特征的尾水治理模式,以期为类似项目的设计、施工提供新的参考。
Pond aquaculture plays a crucial role in China's aquaculture industry,ensuring the supply of high-quality animal protein,promoting agricultural efficiency,and increasing farmers' income.With the rapid development of the social economy,the traditional and extensive pond aquaculture model has highlighted a series of problems,posing requirements and challenges for the improvement and upgrading of the industry.This paper takes a concentrated and contiguous 2050 acre aquaculture pond in Hubei Province as an example to sort out the design ideas of inlet and outlet separation transformation and tail water treatment.Through the construction of new ditches and functional division,the inlet and outlet separation in the project area is achieved,which solves the pollution of upstream tail water discharge on downstream pond water,reduces the risk of fish infection and disasters in aquaculture ponds.At the same time,ecological ditches and lotus pond wetlands are used as the main purification units.After treatment,the COD_(Mn),total nitrogen,and total phosphorus indicators of the aquaculture wastewater steadily meet the second level standards of the Freshwater Pond Aquaculture Water Discharge Requirements(SC/T 9101-2007),greatly avoiding the impact of aquaculture wastewater on the water quality and water environment of the Han River.At the same time,this paper looks forward to the future design and construction direction of the separation of inlet and outlet water and tail water treatment of such ponds,and proposes a tail water treatment model suitable for the characteristics of aquaculture in Hubei Province,in order to provide new references for the design and construction of similar projects.
