This invention belongs to the field of water circulation technology, and particularly relates to a non-discharge cold-point water-for-injection circulation system, comprising: a water storage tank for storing water for injection; and a circulating water pump installed on one side of the water storage tank. The circulating water pump, after being cooled by a heat exchange structure, is returned to the main pipeline via a branch pipe and then flows back into the water storage tank through a connecting pipe, avoiding direct discharge of low-temperature water for injection. This solves the problem of water loss in traditional discharge schemes, reduces the production costs of pharmaceutical companies, and forms a closed loop between the main pipeline and the water storage tank. The branch pipe is connected to the main pipeline through a heat exchange structure, and all return water from the usage points returns to the main pipeline. At the same time, the circulating water pump drives the water flow circulation, ensuring that the flow velocity in the main pipeline meets the subsequent turbulence requirements, inhibiting microbial growth. Several cooling points are set up to support the simultaneous use of single or multiple cooling points, adapting to the room temperature or low temperature water-for-injection needs of different scenarios such as bottle washing machines, ultrafiltration, and disinfectant preparation, thus improving the system's versatility.
