Sludge fermentation device with spiral structure for removing heavy metal ions in water body

Abstract

The invention discloses a sludge fermentation device with a spiral structure for removing heavy metal ions in a water body, belonging to sludge fermentation devices and specifically relating to a sludge fermentation device which can remove heavy metal ions in a water body. The sludge fermentation device comprises a culture chamber like a drill bit structure of a pit drilling machine, wherein a baffle plate is arranged on the outer side of the culture chamber along the spiral direction, and the culture chamber is provided with a step in the horizontal direction; the culture chamber is enclosed by a housing, the bottom end of the culture chamber is connected with a sludge discharge port, the sludge discharge port is connected to the outside via the housing, and a valve is arranged in the position of the sludge discharge port; a sludge feed port is arranged in the position where the top end of the culture chamber is connected with the housing; a cover is arranged in the position of the sludge feed port; a vent hole is formed in the top end of the housing, and a plug is arranged on the vent hole. The sludge fermentation device disclosed by the invention can not only enable sludge to automatically flow out after fermentation to save manpower and material resources, but also realize a good sludge fermentation effect and stability; simultaneously, the device further has a function of adjusting the sludge fermentation effect.

Description

technical field [0001] A sludge fermentation device with a helical structure for removing heavy metal ions in water belongs to a sludge fermentation device and relates to a sludge fermentation device capable of removing heavy metal ions in water. Background technique [0002] Heavy metal ions refer to the ionic state formed by heavy metals losing electrons. Most of the heavy metal ions are produced in the process of industrial production. If they are discharged into nature without treatment, heavy metal pollution will be caused. Therefore, the removal of heavy metal ions in industrial wastewater is also an important link. [0003] Existing heavy metal ion removal methods include chemical precipitation, adsorption, ion exchange and biochemical treatment. Among them, the biochemical treatment method is a method of removing heavy metals in wastewater by means of flocculation, absorption, accumulation, and enrichment of microorganisms or plants, including methods such as biosor...

AI Technical Summary

Problems solved by technology

[0005] 1. The efficiency of removing heavy metal ions is low and the time is long, so that more sludge is piled up;

[0006] 2. The degree of automation is low, requiring a lot of manpower and material resources, and the cost is high;

[0007] 3. The fermentation effect is poor and cannot be fully fermented;

[0008] 4. The oxygen utilization rate is low and the reaction is not complete

[0010] 1. The fermented sludge cannot flow out automatically, and it still needs to consume a certain amount of manpower and material resources;

[0011] 2. Different effects between different layers
