Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 As shown, the present embodiment provides a method for sewage treatment using the KM biological contact oxidation process, the method includes the following steps in turn:

[0034] (1) Sewage enters the grid to remove large-sized floating matter, suspended matter and small solid matter, such as branches, leaves, discarded clothes, discarded plastic bags and solid organic matter, etc.;

[0035] (2) Lift the sewage to the subsequent treatment structure through the lifting pump;

[0036] (3) Remove dense inorganic particles, such as sand, through the grit chamber;

[0037] (4) Enter the anoxic pool, adjust the water quality, and carry out the denitrification process;

[0038] (5) Enter the biological belt biochemical pool, in which the biological belt is arranged, high-efficiency composite bacteria are added, supplemented by micr...

Abstract

The invention relates to a biological contact oxidation process and provides a method for wastewater treatment by utilizing a KM biological contact oxidation process. The method is characterized in that a biological belt and BM (beneficial microorganism) filler are used as carriers, a biological strain with a specific function is immobilized on the biological belt and BM filler, and a modern biological contact oxidation process is combined. By using the method provided by the invention, the removal rates of various pollutants especially ammonia nitrogen by the biological contact oxidation process are greatly improved, the problem of poor ammonia nitrogen removal effect is solved, the effluent stably reaches the national pollutant discharge standard of wastewater treatment plants, and boththe operation cost and investment cost are lower.

Description

technical field [0001] The invention relates to a biofilm contact oxidation process, in particular to a sewage treatment method using the KM biological contact oxidation process. Background technique [0002] The biofilm contact oxidation process with the biological belt as the carrier is widely used in the process of urban domestic sewage treatment. This process has the characteristics of short construction period, quick effect, less land occupation, simple operation and maintenance management, low energy consumption, and low maintenance cost. , but in most contact oxidation process systems, the effluent ammonia nitrogen and total nitrogen cannot reach the standard, which affects the overall effect and is subject to certain restrictions. [0003] In the case of severe eutrophication of water resources in my country, there is an urgent need for a new process that can effectively degrade pollutants such as COD and stably remove ammonia nitrogen. In order to achieve the goals ...
