Problems solved by technology

[0009] Deodorization includes the collection and treatment of odor, but the collection is difficult and cannot be completely collected, and the internal odor of each unit cannot be removed. To deal with odor, new processing units and land need to be added, and deodorization needs to increase the consumption of chemicals and power , the operating cost is high, new facilities and equipment are required for deodorization, and the investment cost is high
In short, the deodorization methods in the prior art have incomplete odor removal and extraction, large equipment footprint, high power consumption, and high investment costs.

Abstract

The invention discloses a process for deodorizing sewage plant by using magnetic nanofiber and relates to the technical field of biological odor treatment for sewage. The process consists of five units including an odor collecting unit, a humidifying and thermal insulating unit, a washing, humidifying and thermal insulating unit, an efficient biological treatment unit, a chemical enhancement unitand a discharge unit. The process for deodorizing sewage plant by using magnetic nanofiber well solves the problems that an existing biological deodorization technology is long in start time, large infloor area and low impact resistance, biological deodorization filler and process which is low in cost, simple to prepare and long in service life are provided, by use of the charcoal carrier function, deodorization microorganism inoculation function of mineralized refuse and the elastic loosening function of polyurethane substances, and the operation life of the device can be effectively prolonged while odors produced by the sewage plant are efficiently treated, so that social benefits and economic benefits are greatly improved.

Description

technical field [0001] The invention relates to the technical field of biological odor treatment of sewage, in particular to a process for deodorizing magnetic nanofibers in sewage plants. Background technique [0002] With the construction of a large number of large-scale urban sewage treatment plants, the odor as an auxiliary product of the sewage plant and the corresponding odor treatment have attracted more and more attention. The odor generated in the process of urban sewage treatment is mainly concentrated in the water inlet pump room, primary sedimentation tank, aeration tank, sludge storage tank, sludge concentration tank, sludge dewatering machine room and stacking shed. These odor-causing substances mainly include hydrogen sulfide , ammonia and other inorganic substances and organic substances such as low-molecular fatty acids, amines, aldehydes, ketones, ethers, halogenated hydrocarbons, etc. According to the analysis, the concentration of ammonia in the compositi...
