Embodiment Construction

[0037] like Figure 1-3 Shown is a magnetic separation sludge treatment system of the present invention, comprising a dewatering tank 1, a magnetization tank 2, a sewage tank 3, a clean water tank 4 and a slag removal tank 5, and the sewage tank 3 is connected to the dewatering tank 1 through a sewage pan 31 The water filter membrane 32 is arranged in the sewage pan 31, and the water filter membrane 32 is set for further filtering work, and separates the granular soil and water, and the water enters the sewage tank 3, and the soil is then Staying in the extrusion cavity 13 makes the water entering the sewage tank 3 clearer without any mud residue, which is convenient for later water treatment. The magnetization tank 2 is connected with the sewage tank 3 through the first water guide pipe 21, the clean water tank 4 is connected under the magnetization tank 2 through the second water guide pipe 41, a filter screen 42 is arranged above the second water guide pipe 41, and the slag...

Abstract

The invention mainly discloses a magnetic separation type sludge treatment system. The technical scheme is as follows: the system comprises a water removal tank, a magnetization tank, a sewage tank, a clear water tank and a residue removal tank, wherein the sewage tank is connected with the water removal tank through a sewage plate, the magnetization tank is connected with the sewage tank through a first water guide pipe, the clear water tank is connected with the magnetization tank through a second water guide pipe, the residue removal tank is connected with the magnetization tank through a guiding and connecting plate, and a clearing cavity, a crushing cavity and an extruding cavity are sequentially formed in the water removal tank from top to bottom. Sludge firstly enters the crushing cavity for crushing treatment and then enters the extruding cavity for extrusion, extruded water is delivered to the magnetization tank from the sewage tank to be magnetized in the magnetization tank, impurities are separated, purified water enters the clear water tank, and the adsorbed impurities enter the residue removal tank. The treatment manner is simple, the efficiency is high, the water removal effect is goof, and the separated water is magnetized, so that the water purification purpose is achieved, soil resources and water resources can be reutilized conveniently, and the system is environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to a magnetic separation sludge treatment system and a treatment method thereof. Background technique [0002] In the existing technology, about 56% of the sludge has been harmlessly treated by building materials, incineration, fertilizer making, sanitary landfill, etc., nearly half of the sludge has not yet been harmlessly treated, and about 1 / 3 of the sludge is treated with "temporary More than 10% of the sludge is unaccounted for, failing to reach the target of 80% sludge harmless treatment and disposal in the State Council's "12th Five-Year Plan for the Construction of National Urban Sewage Treatment and Recycling Facilities". The sludge problem has become a bottleneck in the field of sewage treatment. Compared with foreign developed countries, my country's sludge components have relatively high sediment and heavy metal content, and low organic matter content, resulting in low sludge anaerobic fermentation gas production rate...
