Clear water and muddy water separation process

The invention relates to a clear water and muddy water separation process. The process comprises the following steps: step 1, ore pulp pretreatment, step 2, high-pressure filter pressing, step 3, filter cloth type selection, step 4, filtrate turbidity under different ore feeding pressures, step 5, turbidity detection at different pulp feeding time, step 6, water receiving tank gradient optimization, step 7, clear water and muddy water separation, step 8, clear water and muddy water utilization, and step 9, treatment of a precipitate in a clear and muddy water pool. According to the technical scheme, water quality is continuously detected on line through turbidity and is instantly transmitted to a background control unit, an instruction is sent in real time according to a detection value, an electric gate valve is automatically opened and closed, clear water and muddy water are separated, different water qualities are reasonably utilized in a classified mode, the industrial water standard is met, and the utili
