Development status of domestic sewage treatment equipment

The production of domestic sewage treatment equipment began in the middle and late 1970s. At that time, the standardization, complete set, and serialization of products were very low, and there were few finalized products. Since the beginning of the 1990s, relevant state departments have successively carried out technological transformations on major sewage treatment equipment manufacturing enterprises to improve their manufacturing capacity and manufacturing level. The production level of special equipment for urban sewage treatment and the general equipment supporting it has been improved. Great improvement.

At present, all or major equipment of urban sewage treatment plants with a daily processing capacity of 5, 10, 25, and 50 tons can be made domestically. Among them, domestically produced microporous aerators, high-strength aerators, belt filter presses, various grille decontamination machines, belt filter presses, mud scrapers, sand scrapers, aeration rotary brushes, aerators Air blowers, large sewage pumps, and submersible electric pumps have basically been able to meet the needs of the domestic market, and some products are also exported.

In terms of product design, domestically-made equipment such as sewage sludge lifting systems, mechanical filtration and sedimentation systems, aeration treatment systems, and sludge dewatering treatment systems with a daily processing capacity of 50,000 to 500,000 tons are equivalent to the world in the 1980s. Level and able to provide complete sets of equipment. However, in terms of biogas power generation systems and online monitoring systems, there is still a big gap between domestically produced equipment and developed countries.

In some of the world’s newer technology and equipment fields in the 1990s, there are still gaps to be filled.

In terms of product level, the efficiency of stand-alone equipment for products such as blowers and water pumps with large energy consumption is close to the level of the world in the 1980s. The overall level of complete sets of products is equivalent to the level of the world in the 1970s and 1980s.
