Embodiment Construction

[0029] Raw water passes through I. first-level anoxic disc module; II. second-level anoxic disc module; III. third-level aerobic disc module; IV. coarse filter mud-water separation module; V. fine filter phosphorus removal biochemical module; When there is a requirement for phosphorus removal, the VI. will add phosphorus removal agent system for phosphorus removal.

[0030] Raw water first enters the three-stage tapered pipeline 1, and the diameter of the water flow decreases after entering the pipeline, and the flow rate increases. When it enters the first-level disk anoxic module I, the water flow passes through the water diversion hole 12 designed on the pipeline when the pipeline shaft rotates. Spray onto the bio-disc 9 to increase the contact effect.

[0031] According to the proportion of the contact part between the disk and water, the speed and the water flow process, it is divided into 3 levels, respectively I. The first-level disk anoxic module; II. The second-level ...

Abstract

The invention relates to a disc multi-stage composite biological purification integrated process. The integrated process involves three modules, namely, the cascade disc module (3 stages), the rough filtration muddy water separation module and the fine filtration dephosphorization biochemistry module. Three-stage gradually-reducing pipelines of the cascade disc module serve as disc supporting bodies, biochemical treatment of sewage is achieved through a biological film formed through disc rotation, discs are arranged in a classified mode, biological phases are classified, biodiversity is increased, microorganism reproduction and organic matter degradation are facilitated, and meanwhile the nitration function and the dephosphorization function are enhanced; special filter cloth with the aperture of 5-20 micrometers replaces a sedimentation basin to conduct mud-water separation; dephosphorization agents are put, dephosphorization is enhanced through filter cloth with the aperture of 0.5-10 micrometers, the sewage discharge standard is improved to meet the reuse requirement, and meanwhile the energy consumption utilization rate is increased and technical units are integrated.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular a disc-type multi-stage composite biological purification integration process, which further denitrifies deeply, improves the sewage effluent standard to meet the reuse requirements, and at the same time improves the energy consumption utilization rate, integrates technical units, and realizes the process Intelligent and integrated. Background technique [0002] Recycling of sewage is one of the effective ways to increase revenue and reduce expenditure, reduce water pollution, improve the ecological environment, and solve urban water shortages. The potential for sewage treatment and reuse in my country is huge, and the development of new sewage regeneration processes and methods has broad market prospects. [0003] Adding special disks to the traditional biological treatment system is a kind of biofilm sewage treatment technology. The disks are in contact with air and tank water alte...
