Abstract
A method for treating life refuse incldues such steps as pre-treating, delivering the pre-treated refuse to a degradating tank; introducing saturated steam to a temp. at 173-179 deg.C and under 9 kg/sq.cm of pressure for 60-90 min; and discharging under a pressure controlled at 1.5-3.5 kg/cm2. Its advantage is high degradating effect.
Description
Technical field: the treatment process that the invention belongs to a kind of domestic refuse.
Background technology: existing treatment process to domestic refuse generally has landfill method, burning method and composting process.These methods objectively exist land occupation, contaminate environment, waste problem of resource.Chinese patent by retrieval retrieves application number: 00124817, by name: the patent of invention of " digesting treatment of domestic waste and mud ", this patent disclosure contain the waste disposal method of clearing up technology; Also retrieve the patent No.: 98102867, by name: innoxious, resource utilization, easily sorting, no remaining garbage treating process; This patent also discloses and has contained the waste disposal method of clearing up technology.Though above-mentioned two kinds of patent schemes have solved the existing problem of traditional landfill method, burning method and composting process to a certain extent, but owing to clear up existing problems aspect the processing parameter selected, often make in the refuse treatment to clear up effect undesirable, limited the utilization of waste disposal.
Summary of the invention: technical problem to be solved by this invention be exactly in the refuse treatment that exists of background technology to clear up effect undesirable, limited the utilization of waste disposal.Solving this technical problem the technical scheme that adopts is:, a kind of treatment process of domestic refuse, this method the first step is carried out magnetic separation: promptly remove magnetic substance with magnetic separator, as battery, ironware; Second step that it is characterized in that this method carries out wet type and clears up, the rubbish that is about to the first step processing is transported in the counteracting tank, feeding saturated vapor makes a jar interior temperature be controlled at 173-179 ℃, pressure is at 9kg/cm2, hold-time was at 60-90 minute, before reaching said temperature, water discharge valve is opened at the bottom of the maintenance counteracting tank jar simultaneously, to get rid of the formed water of condensation of condensed steam and to close after reaching temperature; The 3rd step was carried out discharge, opened the discharge gate of counteracting tank, the rubbish after discharging is cleared up, and control discharge pressure is at 1.5-3.5kg/cm2.The beneficial effect that the present invention is had compared with the prior art is: owing to adopt technique scheme, make rubbish when clearing up, obtain the water vapour effect of the temperature and pressure of the suitable contained various compositions of rubbish, clearing up effect significantly improves, the value that the handled thing that is obtained utilizes again improves greatly, various germs thoroughly are killed, eliminate environmental pollution simultaneously, avoided the waste of land resources to use.
The treatment process of embodiment: embodiment 1, a kind of domestic refuse, this method the first step is carried out magnetic separation: promptly remove magnetic substance with magnetic separator, as: battery, ironware; Second step that it is characterized in that this method carries out wet type and clears up, the rubbish that is about to the first step processing is transported in the counteracting tank, feeding saturated vapor makes a jar interior temperature be controlled at 178 ℃, pressure is at 9kg/cm2, hold-time was at 60 minutes, before reaching said temperature, water discharge valve is opened at the bottom of the maintenance counteracting tank jar simultaneously, to get rid of the formed water of condensation of condensed steam and to close after reaching temperature; The 3rd step was carried out discharge, opened the discharge gate of counteracting tank, the rubbish after discharging is cleared up, and control discharge pressure is at 1.5kg/cm2.
Embodiment 2: a kind of treatment process of domestic refuse, and this method the first step is carried out magnetic separation: promptly remove magnetic substance with magnetic separator, as: battery, ironware; Second step that it is characterized in that this method carries out wet type and clears up, the rubbish that is about to the first step processing is transported in the counteracting tank, feeding saturated vapor makes a jar interior temperature be controlled at 175 ℃, pressure is at 9kg/cm2, hold-time was at 90 minutes, before reaching said temperature, water discharge valve is opened at the bottom of the maintenance counteracting tank jar simultaneously, to get rid of the formed water of condensation of condensed steam and to close after reaching temperature; The 3rd step was carried out discharge, opened the discharge gate of counteracting tank, the rubbish after discharging is cleared up, and control discharge pressure is at 2.5kg/cm2.
Claims (1)
