The river sediment sieving, oxidation reducing and deep dewatering device simplifies treating equipment and is stable in operation and strong in adaptability; and dewatered sludge is low in moisture content and low in microbial content.
Description
Technical field
The utility model belongs to a kind of sludge treatment equipment, be particularly related to a kind of river bottom mud sub-sieve, oxidant deweighting, deep dehydrator, be fit to the sludge treatment equipment that the river bottom mud that the desiltings such as river course, harbour, lake, reservoir produce is carried out stabilization, minimizing, harmless treatment.
Background technology
At present, the sludge treatment equipment that is used for river bottom mud, the general employing excavated, concentrated, bio-oxidation, added several steps such as lime stabilization, dehydration, landfill and process, the technique of not carrying out bio-oxidation and using gravity dehydration in above-mentioned steps is also arranged, and these technology processors are complicated, and floor space is large, and processing cost is high, moisture percentage in sewage sludge after the processing is high, and content of microorganisms is high, can't reach stabilization, innoxious requirement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, a kind of river bottom mud sorting, oxidant deweighting, deep dehydrator are provided, it has simplified treatment facility, changed the organic sludge mode of oxidizing, and then improve dewatering performance of sludge, both floor space can be reduced, facility investment and running cost can be reduced again; Dehydrated sludge water ratio, content of microorganisms are low, reach the standard of sanitary landfill fully.
The purpose of this utility model is achieved through the following technical solutions: a kind of river bottom mud sub-sieve, oxidant deweighting, deep dehydrator is characterized in that: it comprises spiral vibration sieve, receiving tank, one-level hydrocyclone separation technology device, secondary hydrocyclone separation technology device, oxidant deweighting retort, mud medicine mixing tank, the plate-and-frame filter press that connects in order and is connected the medicament addition device that is connected with oxidant deweighting retort, mud medicine mixing tank; Oxidant deweighting retort center arranges whipping appts, and automatic relieving valve is installed on top.
Described medicament addition device comprises sulphuric acid soln tank, copperas solution tank, superoxol tank, flocculation agent tank.
Mud is through being pumped into spiral vibration sieve, by I and II hydrocyclone separation technology device, altogether through three physical separating process, then enter the oxidant deweighting retort and add sulphuric acid soln, copperas solution, superoxol, carry out Fenton's reaction, be inorganics with the oxidation operation in the mud by force, the gas of generation is by outside the automatic relieving valve drain tank.Mud carries out the plate-and-frame filter press deep dehydration through adding flocculation agent behind the Fenton's reaction, and filter cake is up to standard, carries out sanitary landfill.
The utlity model has following advantage: 1, simplify treatment facility, both can reduce occupation area of equipment, can reduce facility investment and running cost again; 2, the dehydrated sludge water ratio is low, content of microorganisms is low, reaches the standard of sanitary landfill fully.3, stable, strong adaptability is widely used in river bottom mud stabilization, minimizing, harmless treatment that the desiltings such as river course, harbour, lake, reservoir produce.
Description of drawings
Accompanying drawing 1 is the utility model schematic flow sheet.
Embodiment
Embodiment: as shown in Figure 1 a kind of river bottom mud sub-sieve, oxidant deweighting, deep dehydrator, spiral vibration sieve 2, square receiving tank 3, one-level hydrocyclone 4, secondary hydrocyclone 5, oxidant deweighting retort 6, spiral pump 13, mud medicine mixing tank 14, plate-and-frame filter press 15 sequentially connect; Establish on the spiral vibration sieve 2 into mud pipe 1; Oxidant deweighting retort 6 tank decks are installed automatic relieving valve 8; Medicament addition device comprises sulphuric acid soln tank 9, copperas solution tank 10, superoxol tank 11, flocculation agent tank 12, sulphuric acid soln tank 9, copperas solution tank 10, superoxol tank 11 are connected with oxidant deweighting retort 6 respectively, and flocculation agent tank 12 is connected with mud medicine mixing tank 14.
Principle of work: to spiral vibration sieve, particle diameter is sifted out greater than the coarse sand of 200 μ m the river bottom mud that the desiltings such as river course, harbour, lake, reservoir produce through pump delivery, and the lower mud of sieve enters into receiving tank; Mud arrives the one-level hydrocyclone through pump delivery in the receiving tank, particle diameter is separated less than the medium sand of 200 μ m greater than 75 μ m, mud extraction enters the secondary hydrocyclone, and particle diameter is separated less than the fine sand of 75 μ m greater than 25 μ m, and described coarse sand, medium sand, fine sand all can be used as building materials; The mud extraction of secondary hydrocyclone flows into the oxidant deweighting retort, add according to a certain percentage sulphuric acid soln, copperas solution, superoxol, carry out Fenton's reaction, 95% above organism is oxidized to inorganics in reaction, 95% above microorganism is oxidized kills, extracellular polymeric is destroyed, and the inorganic gas that reaction process produces is discharged by automatic relieving valve; The mud extraction of oxidant deweighting retort enters mud medicine mixing tank, after adding the flocculation agent mixing, enter and carry out solid-liquid separation in the plate-and-frame filter press, because the extracellular polymeric of contained microorganism is destroyed in the mud, the viscosity of mud reduces, so the performance of planar water sharply descends, therefore be easy to dehydration, under the complex reaction of flocculation agent, the moisture content of the cake after the press filtration is below 50%, sanitary landfill is carried out in the mud cake outward transport, and the pressure filter water outlet enters Sewage Plant and processes.
