1. Process of environmental protection treatment
A certain amount of slaked lime is added to the (No. 1) waste water treatment tank, and then the waste water can be poured into the waste water tank after the glass is washed and stirred appropriately.
Use a pH test paper to test the pH of the liquid in the wastewater treatment tank at regular intervals. When the pH value is 7, stop adding wastewater. After stirring, let stand for 12 hours, the upper layer of clear water can be discharged, and the sediment is removed to the garbage pond.
If continuous operation is required, another waste water treatment tank (No. 2) must be built. When (No. 1) tank is left to stand, discharge clean water and clear sediments, (No. 2) tank treats wastewater, and so on.
Environmental protection treatment equipment (according to the processing capacity of 30㎡ wastewater / day)
Wastewater tank specifications: 3.5m long, 3.5m wide, 1.5m high or 4m long, 4m wide and 1.2m high.
The inner wall of the waste water tank is sealed with cement.
The clear water drain is installed with a plastic pipe, and the installation position is determined according to the requirements of the site.
Third, the environmental protection department equipment map
The discharge uses plastic pipes.
The nozzle is sealed with a nylon mesh of about 10 mesh to prevent the discharge pipe from being blocked.
Drain control valve.
The height should be designed to be adjustable to facilitate the discharge of clean water.
If the clean water needs to be recycled after treatment, another pipeline is used to reach the production site.
