Description
Technical field
The invention belongs to technical field of sludge treatment, and relate to a kind for the treatment of process of mud.More specifically, the present invention relates to a kind of mud low pressure hot water solution treatment process and application thereof.
Background technology
Dewatered sludge is the Main By product produced in sewage treatment process, it is not only containing abundant moisture, organism and microorganism, and containing multiple objectionable impuritiess causing environmental pollution such as heavy metals, therefore the improper process of mud probably causes secondary environmental pollution.For avoiding the generation of the problems referred to above, developing some method for sludge treatment and device successively at present, to expect to reduce the harmful substance contents in mud, and by sludge treatment, secondary recovery utilization being carried out to it.Wherein, carrying out thermal hydrolysis process to mud is a kind of effective sludge treatment means.Existing sludge hot hydrolysis treatment all adopts high-pressure saturated steam to heat mud, and usually under higher than the hot conditions of 190 DEG C, is incubated hydrolysis reaction for a long time.Owing to being high pressure high thermal environment for a long time in reactor in treating processes, this treatment process requires the high-tension apparatus that use cost is higher, and energy consumption is high.On the other hand, heating mud, isothermal holding and high-tension apparatus pressure release all consume the long period, cause the length consuming time of whole sludge hot hydrolysis treatment, efficiency lower, and cause the running cost of whole treating processes higher.
Summary of the invention
The technical problem to be solved in the present invention is, energy consumption for sludge hot hydrolysis process for treating of the prior art is large, equipment requirements is strict and processing efficiency is low and cause running cost and the high defect of cost of investment, provides that a kind of energy consumption is little, processing efficiency is high and adopts the low-voltage equipment and attainable mud low pressure hot water solution treatment process that cost is low.
The technical problem to be solved in the present invention is achieved by the following technical programs: provide a kind of mud low pressure hot water solution treatment process, described method comprises:
S1: be that the mud of 70-97% injects in reactor by water ratio;
S2: the saturation steam injecting 1.0-1.59MPa in reactor, when the temperature of mud reaches 150 ~ 180 DEG C, stops injecting saturation steam and mud after obtaining thermal hydrolysis after keeping 0 ~ 30 minute.
Under the effect of heating power and pressure, in mud, the water holding of the solid matter such as organic polymer structure, colloid is destructurized, makes mud by the solid state transformed mud extremely strong for mobility of initial thickness.In addition, high-temperature hot hydrolysis treatment thoroughly can kill bacterium in mud and pathogenic agent, realizes the innoxious of mud.After thermal hydrolysis process, the water holding of mud is destructurized, and the Bound moisture in mud is released, and dewatering is greatly improved, for follow-up processed creates favorable conditions; Simultaneously, microorganism contained by mud is disintegrated, the organic matter of microorganism cells fully discharges an one-step hydrolysis of going forward side by side, and in mud, the dissolving of solid organic matters and hydrolysis make the anaerobic digestion performance of mud be greatly improved, for follow-up Anaerobic Digestion creates favorable conditions.
In above-mentioned mud low pressure hot water solution treatment process, the water ratio injecting mud in described step S1 in reactor is 70 ~ 89%.
In above-mentioned mud low pressure hot water solution treatment process, the water ratio injecting mud in described step S1 in reactor is 80 ~ 85%.
In above-mentioned mud low pressure hot water solution treatment process, in described step S2, in reactor, inject the saturation steam of 1.2 ~ 1.4Mpa.

Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, the invention provides a kind of mud low pressure hot water solution treatment process, the method adopts the saturation steam of 1.0-1.59MPa to carry out thermal hydrolysis process to the mud that water ratio is 70-97%, after mud temperature reaches 150-180 DEG C, the mud stopping keeping can making for 0-30 minute initial thick mud to be converted into when injecting saturation steam mobility is strong, be convenient to processed.
Above-mentioned lignin-sludge for the treatment of carries out in the process heated, and the present invention is contacted by mud and saturation steam (can be described as heating source) direct and heat exchange between mud realizes heating.It is understood to one skilled in the art that the reactor being used as sludge hot hydrolysis treatment at present mainly injects saturation steam from its top, minority reactor injects saturation steam from its top and bottom simultaneously.Because thermal hydrolysis mud before treatment is that thick, heat exchanging process is slow, and in reactor not etc., in heat-processed, in reactor, the mud temperature of different positions is not identical in the position of the mud distance heating source of different zones.
When using thermal hydrolysis treatment process provided by the present invention, first longitudinally getting a little at inside reactor, reactor is divided into upper, middle, and lower part by longitudinally third-class, is namely top near 1/3 of top, 1/3 of close bottom is bottom, and middle 1/3 is middle part.When saturation steam injects from top, bottom is cold zone; When injecting saturation steam from upper and lower simultaneously, middle part is cold zone.In other words, expression used herein " cold zone " means the comparatively far away and therefore region at the mud place that temperature is relatively low in heat-processed of in reactor distance heating source.
In a preferred embodiment of the invention, measure the temperature of mud in cold zone, and with this temperature value for standard judges whether to need to continue to inject saturation steam.The advantage measuring mud temperature in cold zone is: can guarantee that all pending mud of reactor all reaches the required temperature of carrying out net heat hydrolysis treatment, contribute to the abundant hydrolysis of mud in follow-up keep-process; Shorten the treatment time simultaneously, reduce energy consumption and raise the efficiency.
