With the development of industrial production and the improvement of people's daily living regulations, many enterprises choose integrated sewage treatment equipment to treat sewage. However, what are the issues to pay attention to when applying integrated sewage treatment equipment?

1. Currently, the technical design specifications are low

At present, most of the effluent standards for small and medium-sized sewage treatment equipment are first level A/B standards in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002), and it is difficult to pass smoothly. However, Beijing, Tianjin and other places have gradually established industry standards, with effluent CODcr of 30mg/L, BOD of 56mg/L, NH4+- N1.5 (2.5) mg/L, TN15mg/L, TP of 0.3mg/L, and SS5mg/L. The standards for effluent quality testing are becoming increasingly high, and some regions also require the use of recycled water. Therefore, the current processing technology is gradually unable to meet the standardized effluent water quality requirements;

2. Currently, there is an increase in technical operating costs

At present, the common integrated sewage treatment equipment main processing processes include: contact air oxidation, A/O processing technology, MBR, etc. Mixing, hydrolysis acidification tank, lifting, flow back, sludge discharge, etc. have high energy consumption and drug consumption, and even high operating costs. MBR and improved membrane processing technology require higher cost fees, which cannot meet the energy-saving and consumption reduction regulations;

3. At present, the total technical land area is large

At present, green ecological solutions like imitating natural dissolution include artificial wetlands, microbial ponds, and other processing technologies, which require a total area of about 20-30m2 to solve one ton of water. The total area required for activated sludge A/O and improved treatment processes is about 2-3m2, and the total area required for air oxidation or SBR treatment processes is about 1-1.5m2. The total area required for MBR process to solve one ton of water is about 0.5-1.0m2; In the increasingly anxious situation of commercial land, integrated processing equipment still needs to be further improved;

4. At present, there are many and diverse technical equipment

At present, the production process is generally long and involves a lot of machinery and equipment, such as submersible sewage pumps, mixing devices, return pumps, sludge pumps, fans, filtration devices (membranes), dosing equipment, filling materials, etc., which has increased operating costs and increased the difficulty of operation, maintenance and management methods. It is only a smaller version of large and medium-sized sewage treatment plants, which is not suitable for rural areas and other areas with relatively late management methods, and even many solutions for idle equipment;

5. Currently, the cost of technology investment is high

At present, the operating cost of integrated sewage treatment equipment per ton of water is about 7000 yuan, and the smaller the operating scale, the higher the product cost. The key factors are caused by the specifications of the machinery and equipment, the amount of machinery and equipment, and the cost of the machinery and equipment itself. It is urgent to reduce product costs and find convenient equipment with high cost-effectiveness;

6. At present, the business scale of technical solutions is relatively limited

At present, the daily sewage treatment process is limited by production and manufacturing, transportation, and land occupation, and has a low solution capacity. However, it is also limited by the structure and specifications of machinery and equipment. Those with a small solution capacity (operating scale< 10m3/d) are also unable to produce, process, and manufacture, and their application scope is limited. The problem with the "Dalar small car" is more serious, and some processing processes (membranes) are prone to collapse when there is no water seepage in the short term. The activated sludge method needs to be further trained;

7. The current technology has poor practical results in solving low temperature problems

In the cold regions of the northern region, the current integrated processing equipment generally needs to adopt insulation measures (external houses) in winter, which cannot ensure the vitality of sludge and the reliability of system software operation is weak;

8. Current technical hydraulic standard deviation;

At present, most of the hydraulic flow in processing technology is push-flow or thoroughly mixed teaching, which is relatively single. However, the specifications of integrated treatment equipment are small, which is very easy to cause short flow or partial sludge accumulation. Wastewater cannot fully contact microorganisms, the chemical reaction rate is low, and the capacity utilization rate is also low. The structure of the regulating tank and hydraulic flow need to be improved.

Based on the detailed introduction of the issues that should be paid attention to in the application of integrated sewage treatment equipment above, in order to better enhance the operation of machinery and equipment and increase their service life throughout the application process, we must pay attention to the above aspects. The quality of troubleshooting integrated sewage treatment equipment will also affect the application of the facilities, and it is also necessary to pay attention to the above aspects.
