Technical assistance: What documents need to be submitted for the commissioning of a newly built municipal sewage treatment plant?

1. Debugging conditions: (1) All construction of earth-based buildings is completed； (2) Equipment installation completed ； (3) Electrical installation completed ； (4) Pipeline installation completed ； (5) The related supporting facilities, including personnel, instruments, sewage and inlet/outlet pipelines, as well as safety measures, are all fully in place. 2. Preparation for commissioning: (1) Form a dedicated commissioning team comprising representatives from civil engineering, equipment, electrical systems, piping, construction personnel, as well as representatives from the design and construction parties ； (2) Draw up plans for commissioning and trial operation ； (3) Make the necessary material preparations, such as procuring and preparing water (including sewage and tap water), gas (compressed air and steam), electricity, and chemicals ； (4) Prepare the necessary drainage and pumping equipment ； Sandbags and similar items used to block pipes ； (5) Necessary testing equipment and devices (pH meter, test strips, COD analyzer, SS) ； (6) Establish debugging records and inspection files. 3. Water filling method: (1) Conduct water filling tests for each unit in accordance with the designed process sequence ； For small and medium-sized projects, clean water or lightly polluted water (stagnant water, rainwater) can be used entirely ； For large-scale projects, with an emphasis on water conservation, 50% clean water, lightly polluted water, or domestic wastewater can be used, along with half industrial wastewater (as specified in the design requirements). (2) If the building or structure has not undergone a water filling test, the filling is generally carried out in three stages as per the design requirements, that is, 1/3, 1/3, and 1/3 of the total volume. After each filling phase, a pause of 3–8 hours is taken to check for changes in the water level as well as any leaks or pressure resistance issues in the structure’s tank. Special note: For a symmetric water-level partition wall that is not under stress, water should be poured in simultaneously from both sides. Structures that have undergone a water filling test can be filled to full capacity at once. (3) Another purpose of the water filling test is to check whether the water passages are unobstructed, in accordance with the required design water level, so as to ensure proper flow of water at full capacity after normal operation and the proper functioning of overfill protection mechanisms, thereby preventing water leakage.
