How to maintain the domestic sewage treatment equipment in daily application, now the sewage treatment agent manufacturer will give you a brief introduction to check whether the safety protection device of domestic sewage treatment equipment is complete, safe, flexible, accurate and reliable.

Check the screws and tighten them to prevent them from falling off during use. Check the operating handle of the drive system. The position of the electrical switch is correct and not loose.

Check whether the lubrication device is complete, complete and reliable, whether the oil path is smooth, whether the oil mark is obvious, and whether all kinds of transmission parts have been lubricated and oiled. Check whether all kinds of pipes and fittings are in good condition, without running, running, dripping, leaking or leaking.

Check the integrity of the equipment and missing parts and accessories. All tools and accessories shall be placed in order and stored in order.

Clean all parts of the equipment to make the inside and outside of the equipment clean. The dissolved oxygen at the outlet of aeration tank is 2 mg / L. Adjust the aeration rate according to the specific situation, and regulate the air intake by controlling each valve.

The aeration tank should be controlled by adjusting sludge load, sludge age or sludge concentration. When foam and scum are generated in the aeration tank, the causes should be analyzed according to the color of the foam, and proper measures should be taken to restore normal. Turn on the defoamer pump and spray defoamer as needed. The biological phase of activated sludge, the transparency of supernatant, the color, state and odor of sludge should be observed frequently, and the relevant items reflecting the characteristics of sludge should be tested and calculated regularly.

Due to the change of water temperature, water quality or operation mode of aeration tank, abnormal phenomena such as sludge bulking and sludge floating caused by sedimentation tank should be analyzed, and the operation conditions of the system should be adjusted according to the specific situation, and appropriate measures should be taken to restore the normal condition.

1. After the installation of domestic sewage treatment equipment, the inlet valve and outlet valve should be opened first to transport the sewage to the domestic sewage treatment equipment.

2. After the water level reaches half of the height, open the fan inlet valve, turn on the fan, slowly open the fan outlet valve, and then inflate the contact oxidation tank for 48 hours, and then start the domestic sewage treatment equipment. Add to equipment 3 / 4 and vent to tank for 24 hours.

3. Observe the microbial production in water. If there is a layer of orange yellow biofilm, continue to transport sewage, and gradually increase the amount of water. Observe the growth of microorganisms in domestic sewage treatment equipment.

4. Operators of domestic sewage treatment equipment need to observe the situation of domestic sewage treatment equipment, and use the sludge treatment operation of domestic sewage treatment equipment to discharge sludge every 24 hours.

5. Add disinfectant into the disinfection tank as required. After the equipment debugging and running normally, the system can enter the automatic operation state.

6. Dosing is an important part of sewage treatment process. Whether the dosage is reasonable or not is the key to determine the water quality after treatment. Different water quality requirements depend on the amount of drugs added. The dosage of various drugs should be determined by small sample test according to the composition and concentration of influent water.

7. Various treatment agents are transported by fluoroplastic pump. The dose of domestic sewage treatment equipment is measured by their respective glass rotameters and controlled by inlet and outlet valves.
