Example Embodiment

[0025] As shown in Figure 1, the urban sewage treatment system built on the river of the present invention is to install a trash rack 22 on the river, and then the trash rack is sequentially set up with anaerobic treatment section A, aerobic treatment section B, separation and slag discharge Section C; The specific processing process is as follows:

[0026] 1) Anaerobic treatment section: After the river water passes through the trash rack to remove garbage and debris, it enters the anaerobic treatment section, and is added to the pulse fluidized bed by the lifting pump through the inlet pipe. The suspended biological filler in the equipment is added with water The volume expands and fluidizes gradually, and the biofilm on the surface of the filler fully contacts with water, adsorbing organic pollutants and degrading them into CO 2 , H 2 O and N, pulses are generated when the water is full. Under pressure, the water is discharged from the porous outlet pipe through the pulse gener...

Abstract

The invention discloses an urban sewage treatment system which is built on rivers and equipment thereof. A trash rack is arranged on the river; then the trash rack is provided with an anaerobic treatment section, an aerobic treatment section, a separation section and a slag discharge section in sequence; clear water is further purified and carried out reoxygenation by a constructed wetland before flowing into a lake or being discharged. The sewage treatment system established by the invention does not take up land and can be built at the end part of the unnavigable river (the inflow river channel of any lake dian can be suitable); the main equipment is arranged at the riverbanks of both sides or on a lifting platform which is set up on a channel and in the river (on the surface of the water and immersing into the water); the treatment technology is the combination of a biological method, a chemical method and the constructed wetland; the treated wastes can generate energy again. The system has the highly saving investment and the lowest operation cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban sewage treatment system and equipment built on rivers. Background technique [0002] The existing urban sewage treatment plant covers a large area (up to hundreds of acres) and needs to be equipped with a water delivery network. The investment is high, ranging from tens of millions to hundreds of millions of yuan. Only use a single activated sludge process, for NH 3 The removal rate of -N is low, only about 50%. There is nothing that can be done to polluted rivers, and the treated water has high N and P content, which is not suitable for lakes to accept and cannot change the eutrophication trend of lakes. Contents of the invention [0003] The purpose of the present invention is to provide an urban sewage treatment system and equipment built on rivers, which can directly purify and treat water entering lakes and rivers, without the need for water delivery p...
