Embodiment Construction

[0024] Attached below Figure 1-5 , and the present invention will be further described in detail through specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0025] The sewage treatment method of the present invention is to carry out sewage treatment in the integrated sewage treatment device developed by oneself:

[0026] Powered by the generator, the water inlet pump is turned on, the sewage is driven into the sump, and the sewage flows into the anaerobic tank through the water passing device, and anaerobic treatment, aerobic treatment, moving bed biofilm reactor treatment, secondary precipitation treatment, ozone catalysis are started Integrated sewage treatment of oxidation treatment and disinfection treatment, the steps include:

[0027] (1) Anaerobic treatment: Pre-anaerobic treatment is performed first to improve the biodegradability of sewage and achieve partial COD...

Abstract

The invention relates to a wastewater treatment method for wastewater treatment in a self-developed integrated wastewater treatment device. The method comprises the following steps: starting an intake pump powered by a generator to pump wastewater to enter a header tank, pass by a water-filtering device and flow into an anaerobic tank; and starting anaerobic treatment, aerobic treatment, moving bed biological film reactor treatment, secondary sedimentation treatment, ozonic catalytic oxidation treatment and chlorine dioxide defection treatment. The invention adopts the integrated wastewater treatment device for the integrated wastewater treatment of the anaerobic treatment, the aerobic treatment, the moving bed biological film reactor treatment, the secondary sedimentation treatment, the ozonic catalytic oxidation treatment and the chlorine dioxide defection treatment, thereby ensuring the treated water quality and avoiding new environmental pollution while solving the problems of on-site water intake, on-site treatment and on-site recovery. The invention can be used for the wastewater treatment on temporary wastewater sites, such as temporary construction sites, emergent accident sites, disasterproof sites, disaster-reducing sites, and the like and is randomly used for irrigating lawns, green gardens and crops, flushing toilets, and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment method. Background technique [0002] Most of the northern regions of my country are in arid or semi-arid state, and water resources have become so tight that they have become the main bottleneck restricting the rapid economic development of some regions in our country. On the one hand, water resources are scarce, and on the other hand, a large amount of untreated sewage cannot be used, and it also causes serious pollution to the environment and groundwater. Under the atmosphere of global commitment to environmental protection, the sewage treatment industry has become an emerging industry, and it is in the same important position as the production of tap water, water supply, and drainage industries. [0003] After searching, it is found that the patent number is 02144524.9, the publication number is CN1422817A, and the patent name is: the invention pa...
