Abstract

One of the main problems related to environmental protection in Costa Rica is the adequate management and treatment of piggery and dairy wastes. Pig and dairy farms with hundreds to several thousand of animals are in operation without adequate system for treatment and disposal. Manure, urine and rests of food are washed out from the cages with volumes of water not adequately controlled causing a great variation in the volume and concentration of the effluents. This situation has caused the failure of conventional wastewater treatment plants. The successful application of anaerobic technology ‘AFBRs’ to treat the wastewater of dairy milk with the utilization of biogas in order to produce electricity for the dairy equipment in the milk farm located in the province of Cartago, Costa Rica is presented. As result offers to the industrialists an ecologically viable system and with the use of all its by-products, which allows to describe it like a clean production.

乳品废物处理厂的可持续管理及其副产品的利用

哥斯达黎加与环境保护有关的主要问题之一是对养猪场和奶牛场废物的适当管理和处理。拥有数百至数千头动物的养猪场和奶牛场在没有适当的处理和处置系统的情况下运作。粪便、尿液和剩下的食物被从笼子里冲走，而水量没有得到充分控制，导致流出物的体积和浓度发生很大变化。这种情况造成了常规污水处理厂的失效。介绍了厌氧技术“afbr”的成功应用，利用沼气处理牛奶废水，为位于哥斯达黎加卡塔戈省的奶牛场的乳制品设备发电。因此，为实业家提供了一个生态上可行的系统，并利用了所有副产品，这使得它可以被描述为清洁生产。
