Urban sewer sludge purifying device and method

Abstract

The invention discloses an urban sewer sludge purifying device and method. The urban sewer sludge purifying device comprises a first sewage tank, a filter, a sludge extraction pump and a sludge treater. A sewage pipeline is arranged at the upper end of the first sewage tank, the filter is arranged inside the first sewage tank, fixing frames are arranged on the filter, a first filtering layer is arranged between the fixing frames, a second filtering layer is arranged below the first filtering layer, a third filtering layer is arranged below the second filtering layer, a second sewage pump is arranged on one side of the first sewage tank, a water purifier is arranged in the second sewage tank, and a water quality detector is arranged on one side of the water purifier. The urban sewer sludgepurifying device and method has the advantages that sludge and sewage can be separated effectively, and the sludge reacts with reagents through biological decomposition and dewatering and can be prepared into pollution-free chemical fertilizer and building materials, so that environment protection effect is realized; the sludge is synchronously treated and then discharged after reaching standards,so that production benefit is increased.

Description

technical field [0001] The invention relates to the technical field of sewage sludge treatment, in particular to an urban sewer sludge purification device and method. Background technique [0002] With the development of science and the progress of society, modern equipment is gradually coming into people's sight. Modern equipment not only helps people change our living environment, but also makes our life more convenient. While people are pursuing material civilization, they are also pursuing spiritual civilization. A beautiful and clean living environment can bring people physical and mental pleasure and is of great benefit to people's health. [0003] A beautiful environment needs to be maintained by everyone. When it rains, the dust in the air is brought to the ground by the rain, and the muddy water on the ground splashes. With the action of the water flow, the muddy water is brought into the sewer. Over time, a large amount of sludge accumulates in the sewer. It is v...

Problems solved by technology

[0004] The composition of sewage sludge is complex. In addition to containing a large amount of water, it also contains a large amount of organic matter, refractory organic matter, various trace elements, pathogenic microorganisms and parasite eggs, heavy metals and salts. The harmless and resourceful utilization of complex urban sewer sludge has become a new difficulty and new challenge in the comprehensive environmental management work. Therefore, we urgently need to design an urban sewer sludge purification device to solve the above problems
