Description
Technical field
The utility model discloses a kind of sludge from wastewater treatment plant combined bio treatment system, relate to mud decrement recycling treatment field.
Background technology
Along with economic, social development, China's level of urbanization improves constantly, sewage treatment facility high speed development, and sewage load and processing rate are all in steady increase.Excess sludge as sewage disposal by product is also rolling up, and the problem of environmental pollution that mud produces becomes increasingly conspicuous.The random disposal of mud result in secondary environmental pollution, causes severe social influence.
Conventional sludge from wastewater treatment plant process and disposal technology comprise landfill, burning, anaerobic digestion, aerobic compost etc.Wherein, Landfill is simple, easy, cost is low, but easily produces percolate and inflammable gas.If management operating is improper, percolate enters Water table, polluted underground water environment.If the inflammable gas produced is dealt with improperly and can be set off an explosion and burn.The investment of incineration technology treatment facility is large, and processing costs is high, and cost of equipment maintenance is high, and produces strong carcinogen dioxin.And anaerobic digestion techniques refers to that mud under anaerobic, with anaerobic bacterium, the biodegradable organic substance decomposing in mud is become carbonic acid gas, methane and water etc. by amphimicrobe, although part mud, by minimizing, creates methane, the natural pond slag of a great deal of is still had to need process.The compost fertilizer that aerobic compost technology produces is a kind of well soil improvement agent, can increase farmland organic matter, improve Soil structure, reduce the use of fertilizer.But it is large that shortcoming is land seizure amount, because air storage odor pollution is serious, is subject to weather effect compost quality simultaneously.
Consider the shortcoming and defect of sludge from wastewater treatment plant Technology development, the utility model proposes a kind of sludge from wastewater treatment plant combined bio treatment system, the recycling treatment of sludge from wastewater treatment plant can be realized.
The technical scheme that the utility model adopts is: a kind of sludge from wastewater treatment plant combined bio treatment system, comprises blender, hydrolization and acidification tank, anaerobic fermentation tank, solid-liquid separation system, aerobic fermentation tank, interchanger and stench processing system.Sludge of sewage treatment plant sends into blender through sludge pump, adds the stalk after pulverizing and regulates solid holdup, carbon-nitrogen ratio, and regulate the material mixed to pump into hydrolization and acidification tank, the material after acidication pumps into anaerobic fermentation tank and carries out anaerobically fermenting.Hydrolization and acidification tank is semi-enclosed, arranges 2 water screw leaf agitators in tank.Control natural pond liquid quantity of reflux, timing agitation material by pH, temperature, ORP sensor, accelerate anaerobically fermenting.Anaerobic fermentation tank adopts the insulation of steam adjoining pipe, arranges natural pond liquid backflow and revolve the two stirring system of arm stirrer in tank.The methane gas that anaerobically fermenting produces sends into gas-holder, and the natural pond liquid after heat exchange is used for the insulation of hydrolization and acidification tank, anaerobic fermentation tank, aerobic fermentation tank, and temperature in anaerobic fermentation tank and pH regulator.Natural pond slag delivers to aerobic fermentation tank by feed appliance, adds the laggard aerobe fermentation of acting charitably of crushing straw, by sensor control temperature, oxygen level, material stirring.Foul smell collection device is set in the easy foul smell workshop section that produces, discharges after sending into stench processing system purification.
Feature of the present utility model is, this combined bio treatment system comprises blender, hydrolization and acidification tank, anaerobic fermentation tank, solid-liquid separation system, aerobic fermentation tank, interchanger, stench processing system.Sewage treatment plant residual mud sends into blender through sludge pump, and adding the stalk after pulverizing will regulate solid holdup, regulates the material mixed to pump into hydrolization and acidification tank, and polysaccharide hydrolysis is become monose by the extracellular enzyme of this stage decomposition bacterium secretion; Protein transduction turns to peptide and amino acid; Adipose conversion is glycerine and lipid acid; Higher fat and longer chain fatty acid, aromatic acid etc. can be resolved into acetic acid and hydrogen by acid-producing bacteria.Material after acidication pumps into anaerobic fermentation tank and carries out anaerobically fermenting.Control natural pond liquid quantity of reflux, timing agitation material by pH, temperature, ORP sensor, accelerate fermentation.Substrate conversion is CH4 and CO2 by methane-producing bacteria, utilizes H2 reduction CO2 to produce CH4 or utilize formation methane such as producing formic acid.The methane gas that fermentation produces sends into gas-holder.After solid-liquid separation natural pond liquid heated by interchanger after for the insulation of hydrolization and acidification tank, anaerobic fermentation tank, aerobic fermentation tank, and temperature in anaerobic fermentation tank and pH regulator.Natural pond slag delivers to aerobic fermentation tank by feed appliance, adds the laggard aerobe fermentation of acting charitably of crushing straw, by sensor control temperature, oxygen level, material stirring.Foul smell collection device is set in the easy foul smell workshop section that produces, will discharge after stench processing system purification will be sent into.The utility model combines the advantage of anaerobic digestion and aerobic composting process, and processing efficiency is high, and investment working cost is low, fundamentally can solve recycling and the secondary pollution problem of sludge from wastewater treatment plant.
