Abstract

The invention relates to the field of sewage pipelines, and discloses a sewage pipeline sulfide and methane treatment system and treatment method. The treatment system comprises a urine collection pool, and the urine collection pool is used for collecting and hydrolyzing in-situ urine to increase the concentration of free ammonia in the in-situ urine, so that the urine is fed into a to-be-treatedpipe section, and the activity of a biological membrane or sediment of a sewage pipeline is inhibited. The treatment method comprises the following steps: S1, collecting in-situ urine; S2, hydrolyzingthe in-situ urine collected in the step S1 to increase the concentration of free ammonia in the in-situ urine; and S3, adding the urine hydrolyzed in the step S2 into a sewage pipeline, and inhibiting the activity of a biological membrane or sediments in the sewage pipeline through contact. In-situ urine is utilized to realize control of sulfide and methane production in a sewage pipeline; inactivation of microorganisms in a downstream sewage pipeline can be realized without depending on addition of a chemical agent; the method is low in cost, simple to operate, environmentally friendly and wide in application prospect in sewage pipeline maintenance, and local materials are used.

Description

technical field [0001] The invention relates to the field of sewage pipelines, in particular to a sewage pipeline sulfide and methane treatment system and treatment method. Background technique [0002] Sewage pipes are one of the important infrastructures of modern society. However, there are two issues worthy of attention in the daily operation of the sewer system. The first is sulfide, which is a reduction product produced by sulfate-reducing bacteria (Sulfate-Reducing Bacteria; SRB for short) using sulfate and organic substances in wastewater. The conversion of dissolved sulfides to hydrogen sulfide causes corrosion of pipe concrete, reduces the service life of sewers, causes huge losses, and causes severe odor and health problems. The second problem is methane, which is mainly produced by Methanogenic archaea (MA for short). Methane is a strong greenhouse gas, and reducing methane production is the key to controlling its emission to the atmosphere. In addition, the ...
