Integrated sewage treatment equipment operation and management 

1、 Equipment installation steps and requirements 

1. According to the installation and foundation drawings, prepare the foundation based on the size of the installation plan. Prepare the concrete base plate, with an average bearing capacity of 5t/m2. The foundation must be horizontal and should be placed in the concrete

Installation can only be carried out after the end of the foundation pouring maintenance period. If the equipment is installed below the ground level, the relative elevation of the foundation from the ground level shall be based on the dimensions shown in the drawing. At the same time, the excavation width and length around the foundation must be away from the edge of the foundation

Above 600mm for pipeline installation.

2. The installation and connection of pipelines should be taken into account when the equipment is in place. When the equipment is in place, it must follow the instructions for the weight of the equipment and the tonnage of the crane. The installation sequence should be in place according to the on-site comparison diagram, and the position of the cylinder must be in accordance with the instructions

The orientation should not be misplaced, and the spacing between them must be correct.

3. According to the installation diagram, connect the pipeline. After the equipment is in place, fasten the pipeline with a rubber pad to ensure that there is no leakage at the connection.

4. After installation, the equipment and the foundation floor must be connected and fixed to ensure that the equipment does not flow or float. At the same time, sewage must be injected into the equipment (if there is no sewage, other water sources or tap water should be used instead)

Substitution), the filling level must reach over 70% to prevent the equipment from floating. At the same time, check all pipelines for leaks. Each intersection of the water testing pipes must not leak, and the equipment must not be affected by the rise of surface water

Make the equipment misaligned and tilted.

5. After the installation of the equipment is completed without any defects, soil can be used to fill the surrounding areas and gaps of the equipment, and the ground should be leveled. When filling, attention should be paid to: (1) The cover plate of the equipment manhole must be 50mm higher than the ground level to the left

Right; (2) Do not allow soil to block the air inlet on the manhole cover plate.

6. Connect the control wire of the electric control cabinet to the equipment, and pay attention to the direction of the underwater aerator and submersible sewage pump motor when wiring. For example, the basement control cabinet should be placed in a ventilated area and kept dry. Generally, the control cabinet cannot be placed

In the open air. It is necessary to prevent exposure to sunlight, rain, etc. To prevent the control board and wiring terminals from leaking electricity and burning the control board.

7. Attention: (1) The installation site of the equipment must ensure that there is no water accumulation during rain, (2) the outlet pipe of the equipment must be below 0.4m relative to the ground, (3) there must be no heavy objects above the equipment, and no water accumulation is allowed

When large vehicles pass by (referring to those without special design), (4) the equipment is generally not allowed to empty the internal sewage to prevent groundwater from floating the equipment.

8. Please note that the installation diagram and pipeline connection diagram of this equipment are connected according to the standard and layout plan. If the user requires it, it can be arranged arbitrarily, but it must be proposed when signing the contract.

9. Connect the control circuit of the fan and water pump, and pay attention to the correct rotation of the fan and water pump.

2、 Equipment pre use inspection and equipment startup;

1. When starting the equipment, check the circuit, wiring the control cabinet, and ensure that the voltage and current meet the requirements. This control cabinet can simultaneously control one submersible sewage pump, one fan, and is also equipped with a manual

Dynamic, automatic control system. When starting the water pump, check if there is any leakage, water absorption, or blockage in the water pump pipeline.

2. The water pump of this equipment adopts an anti clogging and tearing type submersible sewage pump. The control of the water pump is completed by the liquid level controller by detecting the liquid level in the sewage pool. When the liquid level reaches the working water level from low to high, it starts working

When working as a pump, if the liquid level drops to the warning level, turn off the working pump. When starting the fan, check if the rotation direction is correct and avoid reverse rotation.

3. Sedimentation tank sludge discharge control, electromagnetic valve air lift sludge discharge, sludge discharge cycle of 8 hours, sludge discharge time distribution box factory has been set for automatic control.

4. There are two control methods for equipment control: manual and automatic. Firstly, manual control is used, and the submersible sewage pump fan is manually controlled to start through the button switch on the panel. After the switch is normal, it will automatically switch to

Automatic control.

3、 Cultivation of biofilms;

1. Sewage entering the equipment

2. Start the fan and reduce the oxygen filling capacity of the sludge pump and fan to about half of the normal oxygen filling capacity;

3. Observe the condition of the filling material in the aerobic tank every day. If there is a layer of orange yellow or orange black sticky material on the filling material, it means that the biofilm has been cultivated, and the cultivation interval usually takes 10-25 days to complete;

4. The temperature is generally between 15 ° C and 25 ° C, which is most suitable;

5. If the concentration of raw sewage is too low and the time for cultivating biofilms is too long, it is necessary to add some nutrients, mainly feces or other nutrients;

6. The pH value must be guaranteed between 6.5 and 8.5, and the raw sewage must be in a biodegradable state;

7. For the treatment of industrial wastewater and hospital wastewater, domestic wastewater should be the main source before commissioning. After the biofilm is cultivated, a small amount should be continuously fed into other industrial wastewater to adapt the biofilm to the production of industrial wastewater

Long means that debugging starts normally.

4、 Equipment operation management;

1. Set the water pump and fan to normal state;

2. Operate the program according to the design and regularly observe the growth of the biofilm.

3. In general, place the control cabinet in the automatic position and allow it to perform automatic control. Usually, only one person needs to conduct regular daily inspections, check the operation status, and add disinfectant.

5、 Maintenance and troubleshooting;

1. It must be noted that no large solid substances in the sewage should enter the equipment to prevent blockage of pipelines, orifices, and damage to the water pump;

2. The manhole of the equipment must be properly covered to prevent accidents or the falling of large solid substances;

3. The pH value of the wastewater entering the equipment must be between 6-9, as the acidity and alkalinity of the wastewater can affect the normal growth of the biofilm;

4. The fan needs to be replaced with oil once after about 6 months of operation to improve its service life;

5. It is necessary to ensure that the air inlet of the fan is unobstructed.

6. Troubleshooting.
