Abstract

The invention relates to a combined sludge conditioning tank and a continuous sludge conditioning process. The combined sludge conditioning tank comprises a buffer tank, a sludge and agent mixing tankand a homogenizing tank, wherein the upper portion of the buffer tank is provided with a sludge inlet, the lower portion of the buffer tank is provided with a sludge conveying pipeline communicated with the upper portion of the sludge and agent mixing tank, the sludge conveying pipeline is provided with a sludge conveying pump, an agent feeding port is formed in the top of the sludge and agent mixing tank, a channel for communicating the sludge and agent mixing tank and the homogenizing tank is arranged between the sludge and agent mixing tank and the homogenizing tank, a sludge outlet is formed in the lower portion of the homogenizing tank, and the buffer tank, the sludge and agent mixing tank and the homogenizing tank are respectively provided with an independent mixing stirrer. The invention further discloses a continuous sludge conditioning process using the combined sludge conditioning tank. With the application of the combined sludge conditioning tank to condition sludge, the agent and sludge mixing conditioning effect can be guaranteed to the maximum extent, the conditioning time is shortened, the sludge conditioning efficiency is improved, the number, the volume and the occupied area of the conditioning tank are reduced, and the investment cost is reduced.

Description

technical field [0001] The invention relates to a sludge treatment tank and a conditioning process, in particular to a combined sludge conditioning tank and a continuous sludge conditioning process. Background technique [0002] At present, the sludge conditioning process is divided into batch conditioning process and continuous conditioning process. At present the most common or intermittent conditioning process. The intermittent conditioning process has long sludge conditioning time and low conditioning efficiency. Usually, multiple conditioning tanks need to be built to meet the treatment requirements, which leads to a large area of ​​conditioning tanks, which in turn affects the investment and operating efficiency of the entire sludge dewatering system. [0003] CN 103896475A discloses a conditioning method for high-dry sludge dehydration. The method adopts an intermittent conditioning process, that is, sludge is first added to the conditioning tank, then ferric chlorid...
