Construction quality management of domestic sewage treatment equipment
Construction management
1.Construction arrangement design, construction plan and processing technology are the technical measures and system guarantee of engineering (product) quality in the process of construction and processing. Before the sewage treatment equipment project starts, it is necessary to prepare the construction plan, and it is necessary to formulate the processing technology for the processing of components. Construction arrangement design, construction plan, processing technology must be approved by the technical supervisor before implementation. 2. Construction arrangement design, construction plan, processing technology, construction personnel must abide by, no one may amend. 3. Strengthen civilized construction, civilized production, strengthen the maintenance of products, protect the fruits of labor, any damage to the product, damage to the quality of the product, shall be punished heavily. 4. Strengthen the construction, production management. It is necessary for construction personnel to construct and produce according to construction procedures or production process procedures. If the previous process is unqualified, it shall not be handed over to the next process for construction. 5. Key processes and special parts should be operated according to the relevant work instructions; The operator who is required to hold the certificate can only take the post if he holds the qualification certificate of the corresponding post. 6. Strict implementation of process control, the previous process is not qualified, shall not be handed over to the next process construction; The next process should ensure the effect of the previous process, and maintenance measures should be taken after forming the product to ensure the appearance quality of the product.
Equipment characteristics
1. The equipment is buried in the ground, which is conducive to insulation, and can still operate normally in the northern cold season, without disturbing noise and no odor. 2. Save construction time and infrastructure costs: factory production, site assembly, no need to pre-build messy and expensive cement foundation. 3. High degree of automation: unattended, automatic operation, fault alarm, easy daily management. 4. Simple maintenance: the suspension filler does not need to be replaced, never blocking, no need to backwash; The motor is installed on the ground within reach, which can be easily repaired or replaced; Basically no maintenance costs. 5. Low operating costs: micro-bubble aerator aeration capacity is large, and energy consumption is much lower than other aeration products, small bubble diameter, more dissolved oxygen, oxygen utilization rate is high, so it can be intermittent aeration and low power consumption. 6. High pollutant degradation efficiency: the system is in continuous operation, and the effluent reaches the national "sewage induction and discharge Code" (GB8978-1996) Level 1 discharge code or "Urban sewage Treatment plant pollutant discharge Code" (GB18918-2002) Level 1 B specification. 7. The debugging period is short: the combination filler is easy to hang the film, start fast: the equipment filler is about 15 degrees in the water temperature, and the film hanging process can be completed in 2 weeks. 8. It can stop and start operation at any time: The operation can be suspended if not in use for the time being, at this time the biofilm on the surface of the filler has not died, but exists in the form of spores, once the water aeration, it can recover in a very short time. This feature makes the equipment very suitable for sewage treatment in some areas with large changes in water volume. 9. Unique mobile suspension filler: the equipment is mostly filled with polyethylene or polypropylene plastic filler, the filler has a large surface area. The appearance is easy to adhere to the biofilm growth, and the clever structural design makes the filler not clumping and blocking when used, always has sufficient open space rate, and has outstanding ventilation, water function.
