How to set up the drainage system of purification workshop
The drainage system of purification workshop is also very important. Hefei purification project introduces the drainage of purification workshop. What problems should be paid attention to in the drainage of clean workshop? Let's take a look at it.
first of all, the wastewater from clean workshop must meet the national discharge standard before it can be discharged. There are various kinds of wastewater. Different wastewater has different properties and concentrations. Harmful wastewater must be treated before it can be discharged.
Secondly, the drainage system of clean workshop must have good ventilation device. There will be drainage equipment and gravity return pipe in the clean workshop. The connection equipment between the two must be provided. The water seal device should be installed below the discharge outlet, and the air permeability device must not be less.
again, the floor drain drainage facilities of clean room should be constructed according to the requirements. If the air cleanliness is above grade 6, it is not necessary to set floor drain; if it must be set, it is better to set special floor drain; for clean room with grade 7 or above, it is not suitable to set drainage ditch or pass through drainage riser;
then, clean sanitary equipment should be used in the clean workshop. Equipment that is not easy to accumulate pollutants or easy to clean should be used in clean workshop, and the same is true for pipe fittings or accessories. In addition, fire drainage facilities should be set up in the plant.
