In this paper, we analysed the merits and dismerits of three major RFUS disposal Methods both at home andd abroab. By means of the principles of ecological system, the reasonableNess of comprehensive treatments to RFUS was disscussed, and a compound ecological purificaTion system pattern of Engineering-Nature-Economy was given.It provides a new way to the Disposal of RFUS

There are still some defects in the modern wastewater biological disposal technology. These defects are greater investment, more needed power supply and inconvenient management. In the wastewater purification system of varied organisms, wastewater is purified according to the metabolism of the food chain step by step. The system is composed of three disposal units of microbes, plants and aquatic animals. The organic matter in wastewater is digested and resolved into CO 2, H 2O, NH + 4,...

There are still some defects in the modern wastewater biological disposal technology. These defects are greater investment, more needed power supply and inconvenient management. In the wastewater purification system of varied organisms, wastewater is purified according to the metabolism of the food chain step by step. The system is composed of three disposal units of microbes, plants and aquatic animals. The organic matter in wastewater is digested and resolved into CO 2, H 2O, NH + 4, CH 4 and PO 3- 4 etc. by anaerobe in the first unit. When wastewater flows through the second unit, each component, except CH 4, is absorbed by algae or plants and transformed into cells of plants by dependence of photosynthesis. In the third unit, by the planktons or fish, the excessive microbes and algae are fed on and transformed into animal albumen. Finally wastewater is purified, and its effect can reach the level of the third grade disposal. The wastewater purification technique of varied organisms is a safe disposal technique ecologically friendly to the environment. It will be a new technique of 21 st century. There are many advantages in the wastewater purification system of varied organisms : smaller investment, less running fee and convenient management. It has a good prospect for application, especially suitable for wastewater disposal in small towns.

以活性污泥法为主流工艺的现代污水处理技术 ,存在着工程投资大、运行费用高、管理复杂等缺点 ,按照生物循环基本理论要求是不完善的。多元生物污水处理是按照食物链代谢规律 ,运用生物循环理论 ,设计成微生物—植物—水生动物 3个处理单元。污水中的有机物作为微生物的食料在第 1单元被厌氧微生物消化降解成CO2 、H2 O、NH+ 4、CH-4 等 ,除 CH4 作为生物能源可回收利用外 ,其它物质都是植物的营养物质 ;在第 2单元被藻类等多种植物吸收 ,通过光合作用合成植物细胞 ,并释放氧气。在第 1单元和第 2单元增殖的细胞和藻类成为水生动物的食料 ,在第 3单元被浮游动物和鱼类捕食 ,转化成动物蛋白。污水中的有机物在 3个单元组成的生态净化系统中 ,被多样生物逐级利用 ,最终转化成植物细胞和动物蛋白 ,使污水得到净化 ,达到三级处理水平 ,不产生二次污染 ,是一种安全的、对环境友好的污水处理新技术 ,在国外被誉为 2 1世纪的新科技。该污水净化系统 ,按照生物循环基本理论进行工艺设计 ,通过生态平衡自我调控 ,具有工艺流程简单、投资省、运行费用低、管理简便等优点 ,适合我国国情 ,有广阔的应用前景 ,尤其适用于小...

There are still some defects in the traditional wastewater biological disposal technology>when it has gone through 100 years' application. These defects are greater investment, much power and inconvenient manage-ment. In the wastewater purification system of varied organisms, wastewater is purified according to the metabolism of the food chain step by step. The system is composed of three disposal units of microbes, plants and aquatic animals. The organic matters in wastewater are digested and resolved into CO2,H2O,NH4+,CH4,PO43- , etc. by anaerobe in the first unit. When wastewater passes through the second unit, everyone of them except CH4 is absorbed by algae or plants and transformed into cells of plants by photosynthesis. In the third unit,the exces-sive microbes and algae are eaten by planktons or fish and transformed into animal albumen. Finally wastewater is purified, its effect can arrive at the level of third grade disposal. The wastewater purification technique of varied organisms is an ecological safe disposal technique to environment. It will be a new technique of 21st century. It has a good application foreground, especially is suitable for wastewater disposal in small town.

传统的污水生物处理方法经过近100年的应用和技术改进,其工艺和设备日臻完善,但仍存在投资大、能耗高、管理复杂等缺点。多样生物污水净化系统是按照食物链代谢规律,设置微生物-植物-水生动物3个处理单元。污水中的有机物作为微生物的食料在第1单元被厌氧微生物消化降解成CO_2、H_2O、NH_4~+、CH_4和PO_4~(3-)等,除CH_4作为生物能源可回收利用外,其他物质都是植物的营养物质,在第2单元被藻类等多种植物吸收,通过光合作用合成植物细胞,并释放O_2。在第1、第2单元增殖的过量细胞和藻类成为水生动物的食料,在第3单元被浮游动物和鱼类捕食并转化成动物蛋白。污水中有机物在3个单元组成的生态净化系统中被多样生物逐级利用,最终转化成植物细胞和动物蛋白,使污水得到净化达到三级处理水平,不产生二次污染,是对环境安全的污水处理新技术之一,成为21世纪的新科技。该污水净化系统通过达到自我调控生态平衡,具有工艺流程简单、投资省、运行费用低、管理简便等优点,适合我国国情且应用前景广阔,尤其适用于小城镇污水处理。
