用聚丙烯桶作为小型孵化设备和养殖用水族箱时,用化学物质处理水体的效果常有一定差异.为此设计了一种能有效地处理鱼卵和鱼苗的简易系统,它由装有高浓度化学物质的贮液器、容积式限流泵和相应的供水管道所组成(图1).化学物质不直接注射入各孵化器或水槽中,而是直接注射入供水管内.处理某混合液所需化学物质的数量和混合液的体积可按表1所列方程计算.根据方程式1,被处理水体的总体积取决于出水口个数、各出水口流量和化学处理时间.由方程2,根据所需化学物质浓度、化学物质的
When polypropylene tanks are used as small-scale incubators and aquaculture tanks, there are often differences in the effects of treating chemicals with chemical substances. For this reason, a simple system for efficiently handling fish eggs and fry was designed. Concentrated chemical reservoirs, positive displacement pumps and corresponding water supply pipes (Fig. 1). Chemicals are not injected directly into the individual incubators or tanks, but are injected directly into the supply pipe. Handling a mixture The quantity of required chemical substances and the volume of the mixed liquor can be calculated according to the equations listed in Table 1. According to Equation 1, the total volume of water to be treated depends on the number of outlets, the flow rate at each outlet, and the chemical treatment time. Equation 2 is based on Required chemical concentrations, chemical substances
