The water-saving effect is very significant in some large water treatment systems. Secondly, the cost of this system is relatively low, and the requirements for the water quality of the system's inlet are relatively low, making it easy to promote (and competitive in some water treatment projects of enterprises or factories that require high recovery rates but cannot invest a lot of funds). What types of water pumps are needed in water treatment system engineering? How to choose water pumps from different manufacturers? Answer: Generally, ordinary pumps, booster pumps, and corrosion-resistant pumps are required in water treatment system engineering. Ordinary pumps generally use IS type cast iron water pumps; Generally, stainless steel water pumps such as the Danish Granff imported high-pressure pump are used for booster water pumps (depending on the specific situation); Anti corrosion water pumps generally use IH chemical pumps or engineering plastic water pumps. The models of water pumps from different manufacturers vary. Firstly, select the flow rate of the water pump according to the process requirements of the system; Secondly, select the head of the water pump according to the process requirements (1 kilogram is approximately equal to a head of 10 meters, and 1 MPa is approximately equal to 10 kilograms); Select the material of the water pump again according to the process requirements (mainly referring to the material of the pump head); Afterwards, select the ones that can meet the process requirements and save system energy consumption based on the power consumption of various water pumps. In the design of oxidation ponds and artificial wetlands for treating aquaculture wastewater, it is generally based on the data of oxidation ponds or artificial wetlands for treating other types of wastewater, or designed arbitrarily. However, for livestock and poultry breeding wastewater, there is still a lack of in-depth research and standardization on how much area is needed for oxidation ponds and artificial wetlands to meet the standards, and the impact of seasonal temperature changes on the effectiveness of natural treatment systems. The sludge is returned from the sedimentation tank, which ensures the stable operation of the reflection system, maintains a high organic matter removal rate, effectively prevents sludge expansion, and discharges physical and biochemical residual sludge into the sludge concentration tank. The clear liquid on the concentration tank flows into the regulating tank, and the concentrated sludge is pumped into the sludge filter press for dewatering treatment. Quanwei Environmental Protection Commitment 1. Raw Materials: We insist on using various types of steel produced by large steel mills, whose quality and mechanical properties meet the standards, which can better ensure the quality and performance of the products. 2. Service: With a comprehensive service system and professional service personnel, we provide customers with fast and efficient services.

Process performance characteristics
1. The shell of the sewage treatment equipment is made of carbon steel.
2. The biological treatment tank is equipped with biological elastic packing and has hydrolysis and acidification functions. It can also be adjusted to a biological oxidation tank to increase the biochemical retention time and improve treatment efficiency.
The filling material in the O-grade biochemical tank adopts a three-dimensional mesh composite filling material, which has a large specific surface area, a long service life, and is prone to film formation, corrosion resistance, and blockage. The filling material can freely stretch and diffuse in water, cutting the bubbles in the water in multiple layers, which relatively increases the aeration effect and oxygen utilization rate. The installation, disassembly, and inspection of the filling material in a cage style are convenient.
4. The aeration pipeline in the pool is made of high-quality ABS pipes, which are corrosion-resistant. The aeration head adopts a membrane type microporous aeration head, which is non clogging and has high oxygen utilization efficiency.
5. The fan design uses a high-pressure fan, which has the characteristics of small size, low noise, sufficient air volume, stable and reliable performance.
Electrical Control
This sewage treatment equipment adopts electrical programming centralized automatic control. Once the automatic control fails or changes the required process, the system can be manually controlled to indicate whether the operation is normal or not through signals. In order to reduce the labor intensity of operators and implement automated operation, water pumps and fans can switch automatically.
General technical requirements for equipment installation
Anchor bolt: The bare part of the anchor bolt must be clean and free of oil stains. If necessary, it should be grilled with an open flame to remove oil stains. The threaded part should be coated with grease. After tightening the bolt, it must expose 1.5 to 5 pitches. The distance between the anchor bolt and the foundation hole wall should be greater than 15mm. A distance of 30-50mm should be left between the anchor bolt and the bottom of the hole.
Pad iron: There should be at least one set of pad iron near each anchor bolt, as close as possible to the anchor bolt without affecting the secondary grouting. The spacing between adjacent sets of shims is generally 500mm, and for heavy equipment with large load-bearing capacity, the spacing should be 250mm. Diagonal shims must be used in pairs, with a slope of generally 1/20 to 1/10. For equipment with high center of gravity or large vibration, a slope of 1/20 is recommended. Each group of shims should reduce the number of blocks, generally not exceeding three. When placing them, pairs of diagonal shims should be placed on top, and flat shims should be placed below. The paired diagonal pad iron should have stable contact, with a lap contact length of not less than 3/4 of the total length. Use a 0.25kg hammer to strike each group of pad iron, and the sound should be solid and there should be no looseness. Use a 0.05mm feeler gauge to check that it should not be inserted into 1/5 of the width. After aligning and leveling the equipment, the shim should be exposed from the outer edge of the equipment base, the flat shim should be exposed by 10-30mm, and the diagonal shim should be exposed by 10-50mm.

The start-up of the submersible sewage pump in the regulating pool is controlled by the liquid level float signal in the regulating pool. The float switch is made of fully sealed rubber material and is divided into high, medium, and low switch level signals according to the liquid level in the pool. It is automatically controlled by the PLC control system.
1) When the regulating pool reaches the middle water level, the system is in normal operation and one water pump is turned on;
2) When the water level in the regulating pool is too high (reaching the alarm level), both submersible sewage pumps in the regulating pool are started simultaneously.
When the water level in the regulating tank is at a low level, the compressed air inlet valve of the first and second contact oxidation tanks should be kept open for 10 minutes at intervals of 30 minutes.
The sludge reflux is lifted by the sludge pump and flows back to the hydrolysis acidification tank, controlled by time. The air lift sludge discharge and sludge pump reflux time are staggered.
All types of electrical equipment are equipped with overvoltage, phase loss, short current protection, and alarm functions.
Operating Procedures for Sludge Dehydration Workshop Process
In order to better utilize the equipment, ensure that the sludge treatment meets the design and corresponding discharge standards, and meet the production requirements of the entire plant, the process operation instructions are provided.
Operators should strive to learn this instruction and continuously summarize their experience in production practice, propose rational suggestions for sludge treatment, and improve the level of sludge treatment. During the sludge treatment process, operators should closely monitor the operation of equipment and the effectiveness of sludge treatment, and record in detail the operation process and any malfunctions encountered during operation.
