Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with accompanying drawing description and specific embodiment:

[0021] 1. Grill well

[0022] The sewage is concentrated by the domestic sewage drainage pipe network in the community. The sewage contains a large number of suspended and floating solids with large particles, which are cut off by the grid and removed in time. A sewage pump is placed in the grid well to extract the sewage filtered by the grid to Grease trap. The grid hole size is 10×10 mm to 30×30 mm.

[0023] The setting of the grid well is to remove the large volume of various solid substances in the sewage and reduce the burden of the next process; the second is to ensure the normal operation of the sewage pump without blocking the pump port; the third is to use the sewage pump to pump the sewage It is lifted to the grease trap with the highest level (terrain) in this treatment process, so that the sewage can complete the p...

Abstract

The invention provides a deep cleaning treatment technique for urban sewage. Wherein, the deoiled waste water enters anaerobic pond and oxidation pond, then is deep cleared past the micropore ceramics pond, biological deposition pond, charcoal aeration tank, charcoal decolouration and deozonization pond. The out water achieves natonal III-grade water quality standard for surface water. This invention can prolong effectively the biological chain length and has well treatment ability.

Description

Technical field [0001] The invention relates to a treatment method for eutrophic water body, industrial waste water or domestic sewage, specifically a treatment method for low-concentration waste water, mainly a deep purification treatment process for urban domestic sewage. Background technique [0002] Conventional secondary treatment processes for urban sewage mainly include: A 2 / O process, oxidation ditch technology, SBR process series, biofilm method, biological treatment + constructed wetland process, etc. A 2 / O process, phosphorus and nitrogen removal functions are better, but there are many process control points, high management requirements, and large investment; Oxidation ditch technology, stable operation, good treatment effect, small sludge output, but low load, large floor area , easy to breed mosquitoes and flies, poor management is also easy to pollute the surrounding lakes and the environment; SBR process series, including CASS process, IDEAS (should be c...
