Continuous temporary sludge storage system

Abstract

The invention discloses a continuous temporary sludge storage system, and belongs to the technical field of sludge treatment. The continuous temporary sludge storage system comprises a first storage bin, a second storage bin, a first temporary storage bin, a second temporary storage bin and a third temporary storage bin. A first sludge plunger pump pipe and a second sludge plunger pump pipe which are connected with a feeding pipe are respectively arranged at the top of the first storage bin and the top of the second storage bin. A first discharging valve pipe and a second discharging valve pipe which are connected with a discharging pipe are arranged at the bottoms of the first storage bin and the second storage bin. The first temporary storage bin, the second temporary storage bin and the third temporary storage bin are sequentially connected through overflow pipes. A one-use and one-standby mode or a dual-use and mutual standby mode is adopted. The first sludge plunger pump pipe and the second sludge plunger pump pipe are respectively opened for storage according to the sludge amounts of the first storage bin and the second storage bin, and the first discharging valve pipe or the second discharging valve pipe is selectively opened for discharging according to the temporary storage efficiency. Through multi-stage temporary storage by the first temporary storage bin, the second temporary storage bin and the third temporary storage bin, the sludge treatment rate is improved, stable temporary storage and balanced conveying of sludge are achieved, and the conveying efficiency of a slurry pipeline is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to a sludge continuous buffering system. Background technique [0002] With the rapid development of our country's cities and social economy, the construction of urban drainage infrastructure in our country has been further improved, and the urban sewage treatment rate has also been correspondingly increased. During the rapid development of sewage treatment capacity, sludge, a by-product of sewage treatment, is also produced in large quantities. [0003] The problem of environmental pollution caused by sludge is becoming more and more prominent, and it is easy to cause greater safety hazards, environmental pressure and economic burden. Sludge not only has high water content, is perishable, has a strong odor, but also contains pathogens, heavy metals and harmful substances. If it is not treated effectively, it will easily cause secondary pollution to groundwater and soil af...

Problems solved by technology

[0003] The problem of environmental pollution caused by sludge is becoming more and more prominent, which is likely to cause greater safety hazards, environmental pressure and economic burden

Sludge not only has high water content, is perishable, has a strong odor, but also contains pathogens, heavy metals and harmful substances. If it is not treated effectively, it will easily cause secondary pollution to groundwater and soil after erosion and infiltration by rainwater. pollution, and even directly endanger human health

[0004] Sludge is transported to the factory by truck and unloaded into the steel structure sludge buffer device. In order to increase the processing capacity, we can only choose to simply build a new sludge buffer warehouse, which is costly and can only be unloaded individually when unloading. resulting in a lower sludge disposal rate

Therefore, it is necessary to propose a better sludge buffer treatment system to ensure the continuous buffer treatment of sludge, solve the problem of untimely sludge treatment in sewage treatment plants with weak sludge treatment capacity, and better solve the problem of sludge treatment
