Sludge acidification fermentation treatment system

Abstract

The invention provides a sludge acidification fermentation treatment system which comprises an acidification pretreatment pond, an ultrasonic treatment pond, an acidification hydrolysis pond, an anoxic fermentation pond, a dehydration pond, a pH adjusting device, a first reflux pump, a second reflux pump, a flow monitoring device, a first temperature sensor, a stirring device, a pH monitoring device, a flow adjusting valve, a second temperature sensor, a marsh gas collecting device, an oxygen supply stirring device, an oxygen content monitoring device, a heat preservation layer, columnar separation plates and ultrasonic generators. The sludge acidification fermentation treatment system is provided with an ultrasonic processor, the sludge treatment efficiency is improved, the size of a sludge digestion structure is reduced, and preparations are made for further treatment of sludge. The acidification hydrolysis pond is provided with a temperature monitoring device, the pH monitoring device and the stirring device, the anoxic fermentation pond is provided with a temperature monitor device, the oxygen content monitoring device and the oxygen supply stirring device, it is guaranteed that a reaction is carried out fully, and therefore the utilization efficiency of the sludge is improved, and damage of the sludge to environment is reduced.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge acidification fermentation treatment system. Background technique [0002] As a biological treatment process, activated sludge treatment of sewage is widely used in urban sewage plants and industrial sewage plants. In recent years, the number of urban sewage plants has been increasing, and the excess sludge produced in the process of activated sludge treatment of sewage has grown rapidly. In 2010 alone, more than 6 million tons of dry sludge were produced. If the sludge is not effectively treated and disposed of, it will lead to a series of environmental problems. The sludge disposal in our country is still in a state of serious lag. [0003] Facultative oxygen digestion technology is currently the most commonly used process for sludge treatment in most sewage treatment plants in my country. The sludge is digested with facultative oxygen to generate bioenergy (...
