Wash the instruments that are attached. In that case, in the illustrated example, water can be accumulated in the sink 12 and washed. If the washing water accumulated in the storage tank 14 has reached a certain level that can be perceived as a limit by experience, first, the pH of the washing wastewater is measured using a PH meter, and the storage of equipment The neutralizing agent is taken up from No. 16, and an appropriate amount is charged according to the PH value, and the neutralization treatment is performed so that the washing waste water is within the range of PH 5.7 to 8.7. Next, a flocculant is added to the neutralized washing wastewater, and the faucet 15 is opened to cause a water flow, or the washing wastewater is stirred manually to separate paint components and the like (first filtration). Here, the separated agglomerates are collected by lifting the first separating member 18 together with the basket-like main body, and discarded. Thereafter, the opening / closing part 20 is opened to allow the washing wastewater to flow out to the drain trap 23. At this time, the separated product of the first filtration is filtered by passing through the screen 19c (second filtration). Since mortar aggregate, residue and other solid precipitates have a relatively large specific gravity, they accumulate on the bottom lid 19 and are collected and discarded. The washing wastewater that has passed through the second filtration flows into the second separation means 21 and is filtered by passing through the drain trap 23 (third filtration). The collected matter in the drain trap 23 is recovered and discarded in the same manner as described above. The final drainage is treated by connecting it to a connection destination such as a sewage tank or a separately prepared filter.
