The environmental protection sewage treatment machine is the equipment for treating sewage, which has the purpose of purifying the sewage and protecting the environment. However, during the operation of the environmental protection sewage treatment machine, it is necessary to add a certain amount of coagulant and other agents, so as to ensure the sewage The treatment effect of the equipment. What are the methods for the operation of the equipment?
During the dosing operation, first open the water inlet valve, put a certain amount of industrial water dissolved with the chemical in the mixing barrel, start the mixer, and put an appropriate amount of chemical into the mixing barrel. The coagulant needs to be stirred for 5 to 10 minutes. , The coagulant needs to be stirred for about 30 minutes. After the stirring is completed, open the liquid discharge valve of the mixing tank and the metering pump discharge valve.
When the sewage progressing pump of the environmental protection sewage treatment machine is running, the metering pump can be initiated for dosing. After one drug is dispensed, water can be dispensed to the other mixing bucket for backup. In addition, when the dosing metering pump is linked with the sewage pump, the The drug metering pump should actively adjust the dosing amount through the frequency converter according to the flow signal input by the electromagnetic flowmeter.
Attention should be paid to the dosing operation of the environmental protection sewage treatment machine. When pouring water into one mixing barrel and adding the medicine in this mixing barrel, the liquid outlet valve of the other mixing barrel needs to be closed. When the dosing device needs to be adjusted When repairing, the relevant valve should be closed, and if the mixing tank is to be repaired, the corresponding vent valve should be opened.
All in all, dosing is an important part of the sewage treatment process. Whether the dosing amount is reasonable or not directly determines the quality of the treated water quality, and different water quality requirements have different dosing amounts for environmental sewage treatment machines. The dosage should be determined by a small sample test according to the composition and concentration of the water.
