Embodiment Construction

[0018] Such as figure 1 The first scheme shown is a fixed sludge dump method and device. The sludge dump tank 1 communicates with the bottom of the digester 2 through a mud-water communication pipe 3. The mud-water communication pipe 3 is provided with two valves 6, one Detachable joint (flange) 7, and a pressure water pipe 12, a valve 6 is arranged on the pressure water pipe 12; the top cap 11 of the tank body at the top of the sludge dump tank 1 is connected to the sampling inspection pipe 10 on the side, and the upper part is connected to the muddy water static pressure pipe (well) 4, the upper part of the muddy water static pressure pipe (well) 4 has a digestive gas pipe 8, and the middle part has a muddy water communicating pipe 3 to connect with the digester 2; The valve 6 and a detachable joint (flange) 7 are provided with a sludge discharge pipe 5 on the side of the bottom of the sludge dump tank 1. The valve 6 is installed on the sludge discharge pipe 5 and connected ...

Abstract

The invention provides a method and a device for dump processing of digestion sludge. The device is mainly characterized in that a sludge dumping pool 1 is connected outside a digestion pool 2, the sludge dumping pool 1 is communicated with the bottom of the digestion pool 2 through a sludge water communicating pipe 3, the side surface of a pool body top cap 11 at the top of th sludge dumping pool 1 is connected with a sampling and checking pipe 10, the upper part of the sludge dumping pool 1 is connected with a sludge water static pressure pipe (well) 4, a digestion gas pipe 8 is arranged at the upper part of the sludge water static pressure pipe (well) 4, and the middle part of the sludge water static pressure pipe (well) 4 is connected with the digestion pool 2 through the sludge water communicating pipe 3; and a sludge discharge pipe 5 is arranged on the side surface at the bottom of the sludge dumping pool 1. According to the method and the device, disclosed by the invention, sludge digestion and storage volume can be increased, sludge retention time can be prolonged, the impacts of sludge discharge on sludge digestion can be reduced, and the method and the device are further conductive to sludge disposal.

Description

technical field [0001] The invention relates to a sludge treatment method and device. Background technique [0002] The by-product of sewage treatment is sludge, and improper treatment of sludge will cause secondary pollution. Under the principles of sludge reduction, stabilization, and harmlessness, sludge is generally treated and disposed of, and the commonly used basic methods include concentration, digestion, and other treatment methods. Digested sludge needs to be transported outside for disposal. If the degree of sludge digestion is low, the volume of sludge will increase, the work efficiency will be low, and the time for sludge digestion and treatment will be prolonged, which will help improve the degree of digestion and degradation of sludge. There is a measure that can effectively store sludge with little impact on the original digestion and treatment facilities. Contents of the invention [0003] The object of the present invention is to design a method and dev...
