Abstract

The invention discloses a circulating treatment system for sludge drying carrier gas condensate water. The bottom of a carrier gas condensate water tank is connected with a carrier gas condensate water pump through a pipeline, and then is connected to a sludge storage tank through a condensate water discharge pipe; and the sludge drying carrier gas condensate water is collected to the carrier gas condensate water tank and then discharged to the sludge storage tank through the carrier gas condensate water pump and the condensate water discharge pipe, so that the carrier gas condensate water and sludge in the sludge storage tank are mixed and then enter the sludge treatment facility together to be circularly treated. The circulating treatment system has the advantages that: (1) the drying carrier gas condensate water is independently pumped to subsequent treatment facilities through the special pipe, so that the drying condensate water with higher temperature and malodorous gas is effectively prevented from entering a current sewage pipe network of a plant area and escaping from a sewage well, and the environment of the plant area is effectively improved; and (2) additional arrangement of condensate water treatment facilities is not needed, or impact of organic loads in wastewater on sewage treatment facilities in a current plant area is relieved.

Description

technical field [0001] The invention relates to the technical field of sewage sludge treatment, in particular to a circulation treatment system for sludge drying carrier gas condensed water. Background technique [0002] With the development of my country's social economy and cities, the output of municipal sewage and sludge has increased sharply, and the requirements for the degree of sludge treatment and disposal are also increasing. [0003] As a by-product of sludge drying treatment, the generation of dry carrier gas condensate has brought a series of secondary pollution problems. The sludge after thermal drying is microbially cracked at high temperature, so that a large amount of organic matter is hydrolyzed and enters the circulating carrier gas and condenses, so the condensed water also has high organic loads, ammonia nitrogen and other substances. [0004] At present, most sludge drying projects in my country are usually jointly built with municipal sewage treatment...
