Embodiment Construction

[0027] The present invention will be described in further detail below through embodiments in conjunction with the accompanying drawings.

[0028] see Figure 1~4 , a sludge-free purification treatment device for fixed multiplication microbial sewage, consisting of a sump, an adjustment pond, an aeration pond, a sedimentation pond and a disinfection pond connected to a sewage collection pipe, the sump, an adjustment pond, an aeration pond, a sedimentation pond and The disinfection tanks are connected in sequence. The sewage collected in the collection tank flows through the adjustment tank to reconcile the water quality and then enters the aeration tank for purification. The purified water goes to the sedimentation tank to precipitate silt, and finally goes to the disinfection tank for disinfection and sterilization.

[0029] A screen is installed at the entrance of the sump, and the sewage collected by the sewage pipe enters the sump, and is first filtered through a screen to...

Abstract

The invention relates to a fixed sludge-free reproductive microorganism sewage purifying and treating device belonging to the technical field of sewage treatment. The middle part of an aeration basin of the fixed sludge-free reproductive microorganism sewage purifying and treating device is provided with an air blocking tank, the inner part of the aeration basin is partitioned into a left part and a right part by the air blocking tank, organism nests are arranged in the left part and the right part of the aeration basin and are fixed by grids, and an outlet of an aeration pipeline is positioned in the air blocking tank. When the fixed sludge-free reproductive microorganism sewage purifying and treating device is used for treating the sewage, the sewage collected in a water collecting basin flows through an adjustment basin to be adjusted in the quality and enters the aeration basin to be treated and purified by three layers of biomembranes on the organism nests, then the purified sewage enters a settlement basin for settling sludge, and finally the sewage is sterilized in a sterilization basin and discharged after reaching the standard. Organic matter in the sewage treated in the invention is discomposed and degraded by microorganisms so that the sewage meets the requirements of environmental protection, and the invention has the advantages of simple process, low cost, stable system treatment and no sludge discharge and can be widely applied to the treatment of organic industrial wastewater and urban domestic sewage.

Description

technical field [0001] The invention relates to the technical field of industrial and domestic sewage treatment, in particular to a technology for treating slightly polluted source water, organic industrial wastewater and urban domestic sewage by using microorganisms in an aeration manner. Background technique [0002] With the development of social economy and the improvement of people's living standards, the population of urban residents is increasing rapidly. The dense population brings a large amount of domestic sewage, and the distribution of small factories produces a large amount of industrial wastewater. These untreated domestic sewage, untreated or treated The discharge of industrial production wastewater that does not meet the standards has also increased. When the dissolved oxygen in the water is sufficient, the organic pollutants in the water body can be decomposed by aerobic microorganisms and gradually purified; When the temperature is high, the dissolved oxyge...
