Preparation process of compound calcium hypochlorite cake agent for long-acting slow-release disinfection water body and slow-release performance test method

The invention discloses a preparation process of a compound calcium hypochlorite cake agent for a long-acting slow-release disinfection water body and a slow-release performance testing method, and the preparation process comprises the following steps: mixing a powdery and granular calcium hypochlorite raw material prepared by a calcium compounding method and a granular calcium hypochlorite raw material prepared by a sodium compounding method according to a certain ratio, and then pressing into a cake agent to prepare the compound calcium hypochlorite cake agent. The compound calcium hypochlorite cake agent can be slowly released for a long time to disinfect a water body, the workload of manual feeding is reduced, a slow release performance test experiment of the cake agent shows that the cake agent has good linear continuous slow release performance, the slow release gram weight is stably reduced, the dissolution speed is uniform, the cake agent can stably release residual chlorine for water body disinfectio
