Background technology
At present, the mud of China's urban wastewater treatment firm contracts reaches more than 3,000 ten thousand tons, and traditional treatment process has landfill, burning and soil utilization etc.Wherein, modes such as landfill, soil utilization have all produced serious environmental problem, and burning is crossed the low too high cost pressure that causes because of its calorific value.
The producing methane through anaerobic fermentation of mud technology is the focus of present stage research, but the residue natural pond liquid of generation and natural pond slag also become a kind of waste of handling and utilizing of being difficult to, and cause the pollution of environment.The thermal hydrolysis of mud is that sludge treatment and resource utilization provide a good approach, but wherein needed energy consumption also becomes the limiting factor of China's some areas uses hot water solution.
Summary of the invention
The purpose of the utility model provides a kind of rational in infrastructure, and operation is convenient, and cost is low, and treatment effect is good, and really realizes the anaerobism-full resource utilization treatment system of thermal hydrolysis interlock mud of innoxious, zero release and full resource utilization.
The technical scheme of the utility model is: a kind of anaerobism-full resource utilization treatment system of thermal hydrolysis interlock mud; Comprise mix device, thermal hydrolysis reaction kettle, anaeroic digestor, plate-and-frame filter press, filtrate tanks; The discharge end of said mix device is provided with the spiral pump handling machinery and is connected with the feed end of said thermal hydrolysis reaction kettle and the feed end of said anaeroic digestor respectively through pipeline; The discharge end of said thermal hydrolysis reaction kettle is connected with the feed end of said plate-and-frame filter press through pipeline; The discharge end of said plate-and-frame filter press is connected with the feed end of said filtrate tanks through pipeline; The discharge end of said filtrate tanks is connected with the feed end of said anaeroic digestor through pipeline, and the discharge end of said anaeroic digestor is connected through the feed end of pipeline with said mix device.
Advantage and the positively effect that the utlity model has are: rational in infrastructure, easy to operate, treatment effect is good, take up an area of to economize, and cost is low, can realize innoxiously, and zero release is recycled with full resource utilization.Handle residue obtained and wet mud and compare, volume reduces significantly, and harmful microorganism is all removed, and can process particle and powdered stable prod.

4, anaeroic digestor 5, plate-and-frame filter press 6, spiral pump handling machinery
Embodiment
As shown in Figure 1; The utility model comprises mix device 1, thermal hydrolysis reaction kettle 2, anaeroic digestor 4, plate-and-frame filter press 5, filtrate tanks 3; The discharge end of said mix device 1 is provided with spiral pump handling machinery 6 and is connected with the feed end of said thermal hydrolysis reaction kettle 2 and the feed end of said anaeroic digestor 4 respectively through pipeline; The discharge end of said thermal hydrolysis reaction kettle 2 is connected through the feed end of pipeline with said plate-and-frame filter press 5; The discharge end of said plate-and-frame filter press 5 is connected through the feed end of pipeline with said filtrate tanks 3; The discharge end of said filtrate tanks 3 is connected through the feed end of pipeline with said anaeroic digestor 4, and the discharge end of said anaeroic digestor 4 is connected through the feed end of pipeline with said mix device 1.
The working process of this instance: mud is delivered to mix device 1 by feed pipe; Carry out stirring and evenly mixing therein, and add a certain amount of differential responses medicament, be conveyed into thermal hydrolysis reaction kettle 2 and anaeroic digestor 4 respectively; After treating to carry out the anaerobic fermentation process generation biogas of mud in the anaeroic digestor 4; After equipments such as the gas fired-boiler that biogas is established through other, burning kitchen range are realized the conversion of heat energy, be input to thermal hydrolysis reaction kettle 2 and be wherein heat-conducting oil system heating, carry out thermal hydrolysis and react.
After carrying out the hydrolysis reaction of 1-5h in the thermal hydrolysis reaction kettle 2; Wherein hydrolysis material tablet frame pressure filter 5 filters; The solid residue water ratio that obtains is below 50%; The raw material that can be used as preparation greening soil carries out recycling, as the solid residue water ratio that obtains can directly be processed as fertilizer and biological organic fertilizer through modes such as granulations below 40%; The filtrating that obtains is loaded in the filtrate tanks 3 temporarily, and the raw material that the filtrating composition can be used as preparation egg self foaming agent, liquid fertilizer carries out recycling, also can get into sewage work's sink drainage and carry out purifying treatment.
Filtrate tanks 3 is connected with anaeroic digestor 4; Organic filtrating of the comparatively high temps that is produced by plate-and-frame filter press 5 is loaded in the filtrate tanks 3 temporarily; When treating that temperature is reduced to 70 ℃, can import in the anaeroic digestor 4, in order to the insulation of thermophilic digestion process; Improved simultaneously the organic content of anaerobic digestion material greatly, improved and produce biogas efficient.
The residue natural pond liquid and the natural pond slag that produce in the anaeroic digestor 4 also can be back to mix device 1 through pumping system, carry out recycling treatment through being delivered to thermal hydrolysis reaction kettle 2 behind the mixing, make it to reach innoxious and effect recycling,
In anaerobic gas generation amount less winter, can assist and use steam, Sweet natural gas or electric energy etc. that thermal hydrolysis reaction kettle 2 is heated, the speed of accelerating to produce the organic filtrating of high temperature is back to anaeroic digestor 4, improves gas producing efficiency.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
