Integral type digestion tank

Abstract

The invention relates to an integral type digestion tank. The tank comprises a casing, wherein a slag outlet is arranged at the top of the casing, a slag outlet cover is arranged on the slag outlet, two baffles are arranged in the casing, through-holes are arranged on the upper portions of the baffles, a hollow cavity of the casing is separated into a primary anaerobic chamber, a secondary anaerobic chamber and a clarifying chamber, a water inlet pip is arranged on the side wall of the primary anaerobic chamber, a water outlet pipe is arranged on the side wall of the clarifying chamber, biodegradation processing systems are arranged in the primary anaerobic chamber and the secondary anaerobic chamber, drainage pipes are arranged on the baffles of the primary anaerobic chamber, the secondary anaerobic chamber and the clarifying chamber, the drainage pipes are communicated with the through-holes, and an adverse current hole which flows in a single direction is arranged on the upper portion of a baffle of the primary anaerobic chamber. The digestion tank is simple in structure, the purifying effect can be improved effectively, the corrosion resistance is good, and sludge is convenient to remove, so that the labor intensity of workers can be reduced.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an integrated septic tank.

There are through holes on the partitions between the treatment chambers. Sewage, etc. reaches each treatment chamber through the through holes on the partitions of the treatment chambers, and then undergoes fermentation, filtration and sedimentation to carry out sewage treatment.

Problems solved by technology

[0002] At present, most of the septic tanks used in urban and rural areas are generally three-compartment septic tanks, which are generally composed of multiple anaerobic chambers and clarification chambers. There are through holes on the partitions between the treatment chambers. Sewage, etc. reaches each treatment chamber through the through holes on the partitions of the treatment chambers, and then undergoes fermentation, filtration and sedimentation to carry out sewage treatment. The existing septic tanks have large through holes on the partitions, and the sewage passes through the passages. When the hole is opened, large pieces of debris can still enter the next-level treatment room, so that the dirt cannot be completely removed, so that the final outflow of pollution still seriously pollutes the environment and does not meet environmental protection requirements; in addition, due to the existing septic tank There is sludge accumulated at the bottom of each treatment chamber, so when cleaning, it is necessary to open the partitions of each treatment chamber to carry out manual cleaning, which is time-consuming and laborious, and the labor intensity of the workers is high, which is extremely inconvenient to use

In addition, the existing septic tanks are generally brick or steel-concrete structures, which are prone to leakage after long-term use, which is likely to affect the quality of groundwater and the safety of surrounding buildings.
