Disclosed is a PIG high-elasticity pressurized pneumatic elastic cleaning technology. By combining PIG cleaning with chemical cleaning, to-be-cleaned pipelines are subjected to PIG cleaning and chemical cleaning in sequence. The PIG high-elasticity pressurized pneumatic elastic cleaning technology combines PIG cleaning with chemical cleaning, thus efficient and low-cost cleaning of the pipelines is achieved, adaptability is high, the PIG high-elasticity pressurized pneumatic elastic cleaning technology is suitable for cleaning of the super-long pipelines, and a multi-layer cleaning mode can beadopted; through PIG cleaning, the position between two PIGs can be filled with a chemical agent for cleaning, rinse water or air in the pipeline cleaning process, the cleaning, passivation and drying processes can be completed correspondingly, the cleaning technology is greatly simplified, the investment of a large number of drugs and equipment is saved, the more economical and more environmentally friendly effects are achieved, the construction period is greatly shortened, and meanwhile, the gas purging cost is saved greatly.

The invention discloses a synchronous denitrification reactor. The synchronous denitrification reactor comprises a first order reaction chamber, a second order reaction chamber, a inlet water mixing chamber, a carbon source adding pipe, a mixing stirring device, a backwash water pipe, and a spherical filling material; the first order reaction chamber and the second order reaction chamber are connected in series; the first order reaction chamber comprises a first water preparation oxygen release chamber and a fist denitrification chamber; the second order reaction chamber comprises a second water preparation oxygen release chamber and a second denitrification chamber; the bottoms of the first denitrification chamber and the second denitrification chamber are designed to be tapered; the bottom of the first denitrification chamber is provided with a hole; the bottom of the second denitrification chamber is provided with a hole; the outside edge of each of the holes is covered with filling material blocking screen; and the spherical filling material is injected into the first denitrification chamber and the second denitrification chamber. According to the synchronous denitrification reactor, synchronous denitrification anoxic conditions are achieved in an aerobic tank or an anoxic pool via insulation, biomembrane loaded with the spherical filling material is used for reaction of nitrates and nitrites in backflow sewage with the added carbon source, and generated nitrogen overflow, so that denitrification is realized.
