Abstract

The invention relates to an earthworm ecological treatment reactor for municipal sludge. The reactor comprises a barrel cover (1) and at least two mutually connected barrels; wherein the upper mouths of the barrels are provided with the barrel cover (1); each barrel comprises a barrel wall (2) and a barrel bottom plate (3); handles (4) are symmetrically arranged on the peripheral upper parts the each barrel wall (2), and the outer diameter of each barrel wall (2) is smaller than the outer diameter of the barrel cover (1); a barrel foundation ring (5) is arranged the lower part of the inner wall of each barrel wall (2); the diameter of each barrel bottom plate (3) is smaller than or equal to the inner diameter of each barrel wall and is larger than the inner diameter of each barrel foundation ring (5); and each barrel foundation plate (3) is provided with a plurality of round holes (6). The earthworm ecological treatment reactor is simple to manufacture and low in cost, and is suitable for both the small-scale treatment and the mass treatment of the municipal sludge.

Description

technical field [0001] The invention relates to an urban sludge treatment reactor, in particular to an urban sludge earthworm ecological treatment reactor. Background technique [0002] At present, when earthworms are used to treat urban sludge on a large scale, it is difficult to solve the problems of automatic separation of adult worms and worm eggs, anaerobic bottom of the reactor, and continuous and uninterrupted treatment process at a low cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple and low-cost urban sludge earthworm ecological treatment reactor. [0004] In order to solve the above problems, a kind of urban sludge earthworm ecological treatment reactor according to the present invention is characterized in that: the reactor is composed of a barrel cover and at least two interconnected barrels; The barrel cover is placed; the barrel body includes a barrel wall and a barrel bottom plate; h...
