Abstract

The invention discloses a low-energy-consumption intensifying-denitrifying integrated reactor. The integrated reactor comprises a filter tank, a regulating tank, a biochemical reaction tank and a settling tank, wherein at least one stage of reaction unit is arranged in the biochemical reaction tank; each stage of the reaction unit comprises an anoxic region, an aerobic region, an aeration pipe and an aeration system, the top and bottom of the aerobic region are communicated with the top and bottom of the anoxic region so as to realize hydraulic circulation between the aerobic region and the anoxic region, the aeration pipe is arranged at the bottom of the aerobic region, the aeration system is used for supplying oxygen-containing gas to the aeration pipe, and sewage is nitrified in the aerobic region and is denitrified in the anoxic region. According to the low-energy-consumption intensifying-denitrifying integrated reactor, by virtue of the hydraulic circulation between the aerobic region and the anoxic region, the nitrogen and phosphorus removal efficiencies are improved; during the operation of the process, the occupied area is small, the applicability is strong, the monitoring is convenient, and the operation cost is low.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an integrated reactor for enhanced denitrification with low energy consumption. Background technique [0002] With the continuous improvement of living standards, people's requirements for living environment are also getting higher and higher. In addition to the need for sewage treatment in cities, rural areas also begin to need sewage treatment. In China, especially in hilly and mountainous areas, rural residents live very scatteredly. If centralized sewage treatment facilities are adopted, the construction cost of the pipe network will be high, accounting for more than 50% of the total investment cost, and the pipe network is easy to be damaged and blocked, resulting in sewage collection. low rate. Therefore, centralized sewage treatment facilities are not suitable for use in rural areas, and it is necessary to develop small complete sets of technologies suitable for...
