Embodiment Construction
[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] The rectangular secondary sedimentation tank is a new type of sedimentation process, which realizes the water inlet and outlet on the same side in the rectangular tank body. The volume utilization rate of the tank body is high, and the hydraulic load is higher. Simple. However, the current research on the optimization of rectangular sedimentation tank design is still relatively limited, which limits its engineering application to a ce...

The invention discloses a hundred-ton-level rectangular secondary sedimentation tank which comprises a rectangular tank body which is divided into a tank top and a tank bottom corresponding to the tank top in the height direction; the water inlet system comprises a water inlet tank, and the water inlet tank is arranged on the side wall of the pool top; the water inlet buffer area is arranged along the height direction of the pool body, the upper part of the buffer area is arranged at the water inlet of the water inlet groove, and the lower part of the buffer area is arranged at a preset height from the pool top to the pool bottom and is used for conveying sewage into the pool body at the preset height from the pool top to the pool bottom; the water outlet system comprises a water outlet groove and a water outlet pipe communicated with the water outlet groove, the water outlet groove is formed in the side, away from the side wall of the tank body, of the water inlet groove, and the horizontal height of the water outlet groove is larger than that of the lower portion of the buffer area; and the sludge discharge system is arranged at the bottom of the tank body. The device is simple in structure, good in flowability, high in volume utilization rate of the tank body, capable of increasing the deposition speed of sludge and suitable for small-flow sewage treatment.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a 100-ton rectangular secondary sedimentation tank. Background technique [0002] Integrated sewage treatment technology is a sewage treatment technology that integrates multi-stage sewage treatment systems. It has the advantages of high integration and convenient operation, and conforms to the characteristics of scattered sewage treatment in rural areas in my country. Due to the continuous operation and simple control of A / O method and A2 / O method, they have been widely used in rural integrated sewage treatment equipment. [0003] The secondary sedimentation tank is widely used in sewage treatment. It is an important part of the A / O method and the A2 / O method. Its function is to realize the separation of sludge and water in the effluent of the biological tank. concentration. Common large and medium-sized sewage treatment plants mostly use circular radial...
