Integrated equipment for concentrating and conditioning river and lake bottom mud

Abstract

The invention discloses integrated equipment for concentrating and conditioning river and lake bottom mud, and relates to the technical field of sewage and sludge treatment. The integrated equipment comprises a steel structure pool body and a mixing and conditioning mechanism arranged in the steel structure pool body, the mixing and conditioning mechanism comprises a guide cylinder and a stirring assembly, and the guide cylinder is installed above the pool bottom of the steel structure pool body through a fixing piece; the stirring assembly comprises a stirring motor and a stirring impeller arranged on an output shaft of the stirring motor, the stirring motor is fixed to the steel structure pool body above the guide cylinder, and the stirring impeller is located in the guide cylinder; and the steel structure pool body is connected with a sludge outlet pipe, a sludge inlet pipe, a water outlet pipe and a dosing pipe, the sludge outlet pipe communicates with the bottom or the lower part of the steel structure pool body, the water outlet pipe communicates with the upper part or the top of the steel structure pool body above the guide cylinder, and one end of the dosing pipe communicates with the inner cavity of the guide cylinder. According to the invention, the concentration efficiency is high, the investment is not high, the occupied area of equipment is small, and the concentration and conditioning can be carried out together under the condition of controlling the cost.

Description

technical field [0001] The invention relates to the technical field of sewage sludge treatment, in particular to an integrated equipment for thickening and conditioning river and lake bottom mud. Background technique [0002] River and lake sediment is a mixture of clay, silt, organic matter and various minerals, transformed and deposited at the bottom of the water body, and is an important part of the aquatic ecosystem. At present, the concentration methods of river and lake bottom sludge mainly include gravity concentration and mechanical concentration. The former is a natural sedimentation separation method using gravity, and the purpose of concentration is achieved by forming a high-concentration sludge layer in the sediment without additional energy. One of the most energy-saving sludge concentration methods, but the gravity concentration time is long and the concentration effect is poor; the latter is through the external force of mechanical equipment such as air flota...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the existing concentration equipment cannot not only take into account the operation cost but also ensure the concentration efficiency, but to provide an integrated equipment for the concentration and conditioning of river and lake sediment. The equipment not only has high concentration efficiency, but also has low investment. Occupies a small area, and can carry out concentration and conditioning together under the condition of cost control
