摘 要:根据对我国北方城市污水处理氧化塘的生态系统的调查和综合系统分析,按照能量在食物链中以1/10的剩余值,从低营养级往高营养级逐级传递规律,对生态塘中的生态系统(由分解者、生产者和消费者构成)对物质和能量在食物链中的传递进行了定量分析。根据调查和综合系统分析结果,提出了生态塘系统中各种物种的优化组合与分配的设想,由此构成的食物链(网)能高效进行物质和能量逐级传递,从而使污水中有机污染物得到有效的生物降解,同化、转化和高效地去除。Based on the investigation on ecological system in the municipal wastewater treatment pond system in a city, Hei-longjiang and according to the assumption of energy transfer in food chains at a reduction factor of 10 setp by step form the organism at low trophic level to that at the next higher one, the econlogical system, the food chains that consist of various species of decomposers, producers and consumers through fish farming, duck/geese raising and aquatic plants growing, was analyzed quantitatively in terms of mass and energy transfer in the food chains, with the solar as initial energy source that promoterd the operation of the eco-pond system. On the basis of the investigation and analytical results of the existing eco-pond system, the optimal species distribution in the food chains of the eco-system was presented, which could improve the energy and mass transfer in the food chains at high efficiency, and thus the organic pollutants presented in influent will be removed efficiently through bio-degradation assimilation and transformation in the food chains.
