Abstract

The invention provides a treatment system for removing COD and ammonia nitrogen in steam. The treatment system comprises an acid gas washing system and an alkali gas washing system, wherein the acid gas washing system comprises an acid gas washing tower, an acid spray system, an acid tower circulating pump communicating with the acid gas washing tower and the acid spray system, a first pH system, an automatic acid filling system, an acid demister and an acid tower slurry pump; a bottom outlet of the acid spray system communicates with an inlet of the acid gas washing tower; the alkali gas washing system comprises an alkali gas washing tower, an alkali spray system, an alkali tower circulating pump communicating with the alkali gas washing tower and the alkali spray system, a second pH system, an automatic alkali filling system, an alkali demister and an alkali tower slurry pump; a bottom outlet of the alkali spray system communicates with an inlet of the alkali gas washing tower; and a steam outlet in the top of the acid gas washing tower communicates with a steam inlet of the alkali spray system through a steam pipe. The system is small in floor area, low in energy consumption and large in throughput, and high COD and high ammonia nitrogen wastewater can be effectively treated.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to a treatment system for removing COD and ammonia nitrogen in steam. Background technique [0002] During the "13th Five-Year Plan" period, it is necessary to fully realize that all water is a treasure. my country's water body governance needs to focus on realizing that water pollution prevention and control must start from source reduction, and also recognize that sewage and waste water are valuable resources. We must strive to achieve Sewage and waste water recycling and energy conversion. At the same time, attention should be paid to the research and application of sewage and waste water treatment technology, so as to improve the recycling rate of water resources. As far as Beijing's water shortage is concerned, the sewage reuse rate in Beijing is less than 50%, while Israel's water situation is similar to Beijing's, but its water reuse rate has reached 90%. Israel's agricultural p...
