摘要

摘要: 本研究在室内受控条件下,在虾、贝、藻的多池内循环养殖的基础上,采用残饵污染控制技术减少残饵生成量,并针对对虾养殖中产生的主要目标污染物质及其存在形态,镶嵌以相应的生物修复技术,探讨了综合生物修复技术对对虾养殖生态系统自身污染的修复效果。研究结果表明:采用虾、贝、藻及生物滤池综合生物修复技术可有效降低养殖水体中的悬浮物、溶解无机碳和溶解有机碳的含量。残饵即时修复技术可显著减少残饵生成量,但梭鱼和沙蚕对沉积物的扰动作用对综合生物修复效果产生了一定的负面影响。综合生物修复技术中大型藻类对水体中溶解无机氮的修复能力略显不足,在实际修复过程中需充分考虑大型藻类固氮速率和系统内生物排氮速率的平衡关系,并确保能满足大型藻快速生长最佳的水层空间。单靠微生物滤池对水体中有机物的修复能力并不理想,需辅助增加泡沫分离等技术,提高系统对大分子胶体的去除能力。本研究为进一步构建现场对虾养殖环境的综合生物修复技术体系奠定了基础。

Abstract: This study investigated the integrated bioremediation techniques for a shrimp culture system to reduce unconsumed feed and the contents of suspended solids (SS), nutrients and organic pollutants using barracuda, clamworm, scallop, large algae and a biofilter. A multi-pool internal circulation system was designed to test the effectiveness of the techniques in the laboratory. The experimental result has shown that Argopecten irradians, Gracilaria lemaneiformis and the biofilter efficiently reduced the contents of SS, dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC) in the breeding wastewater. The amount of unconsumed feed was significantly reduced by barracuda and clamworm, but there was an increase in the contents of SS, DIC and DOC in the water due to disturbance by the barracuda and clamworm. The capacity of macroalgae to extract inorganic nitrogen was insufficient. However, the balance of the nitrogen fixation rate of macroalgae and the biological exhaust nitrogen rate within the system should be fully considered. The use of the biofilter alone was not optimal for the remediation of organic matter in shrimp effluent so that auxiliary foam separation technology is needed to improve the ability of the system to remove macromolecules. This study provides a basis for the further development of remediation techniques to reduce the environmental impact of shrimp aquaculture.
