As far back as 1912, Clarke (Clark) and Gage (Gage) were contained in sewage in vial, test.They find the long-time aeration of sewage be there will be to mud in vial, water quality also be improved significantly.They further find, those are not had to wash clean and the bottle that is attached with mud as the sewage aeration experiment, wastewater treatment efficiency is better.They claim that this mud of oneself growing is " active sludge " (Activated Sludge).The main component of this kind active sludge is exactly zoogloea, and zoogloea has very strong absorption, the ability of oxidation of organic compounds, and good settlement action is arranged.
In the present embodiment, this gas pipe line comprises for example circular ring-type main pipe line 21 and is evenly distributed in the pillar pipeline 22 on this ring-type main pipe line, and this pillar pipeline 22 is at least 3, for example 4; Wherein this ring-type main pipe line 21 is provided with the port (not shown) for input air, and ring-type main pipe line 21 can be arranged on the top of this guide shell or this filter basket.This pillar pipeline 22 is positioned at the outside of this guide shell 30 and extends to the bottom of this slop pail 10.In the present embodiment, this pillar pipeline 22, apart from the lower surface close together of this slop pail, only leaves the little space that air filled cavity can be emerged is got final product, and the air filled cavity of exporting is contacted with more sewage, strengthens the effect of sewage disposal.
Specifically, air enters into each pillar pipeline 22 from ring-type main pipe line 21, and enters sewage from the end of pillar pipeline 22 form with tiny bubble, has increased the dissolved oxygen content in sewage, also make mixed solution be in the state of vigorous agitation, form suspended state.Dissolved oxygen, active sludge mix mutually, fully contact with sewage, and activated sludge reaction is normally carried out.
In the first stage of activated sludge reaction, the organic pollutant in sewage is adsorbed on zoogleic surface by activated sludge particles, and this is due to the huge specific surface area of zoogloea and polyose emplastic.Some larger molecular organicses can be decomposed into small organic molecule under the effect of bacterium extracellular enzyme simultaneously.
In the subordinate phase of activated sludge reaction, microorganism, under the condition of oxygen abundance, absorbs these small organic molecules, and oxygenolysis, forms carbonic acid gas and water, and a part is supplied with the propagation procreation of self.So, in sewage, organic pollutant is degraded and is removed, and active sludge itself is multiplied growth, the sewage processing that is purified.
In the present invention, the design volume of slop pail 10 should be relevant to the sewage volume entered, and is pre-designed, therefore not there will be the overflow problem.The useful volume of slop pail 10 should be considered sewage load every day, number, building type (house, office, amusement, hospital, kindergarten, hotel, industrial enterprise's welfare quarter, dining room, kino, stadium etc.), dwell time of sewage, structure (brick, concrete etc.) etc.Specifically, suppose this sanitary sewage pretreatment unit be the processing number be the approximately sewage of 3 tons/day of 1 family discharge of 4 people, so, the useful volume of this device can be the 3-4 cubic meter, if the radius of slop pail is 1 meter, its height should be 1-2 rice so, and the factor of above-mentioned consideration plays fine setting to the concrete size of staving.
The present invention is arranged on filter basket 50 below of rising pipe, and its shape is consistent with the staving of slop pail 10 with size, if such design makes in the sewage entered to have had some impurity, those impurity can be filtered basket 50 and hold back, and the sewage that enters into the slop pail bottom has lacked these impurity, it contacts the effect of processing with air will be better.Filter basket 50 of the present invention is arranged on the top of rising pipe 12 in addition, from pipeline 12, flows out together with water outlet to avoid the foreign material such as particle of assembling in filter basket 50, guarantees the cleanliness factor of water outlet.In the present embodiment, this filter basket 50, lower than the upper limb of this guide shell 30, that is to say, the sidewall of this guide shell 30 has passed this filter basket 50.Filter basket 50 can consist of corrosion-resistant material, and for example resene, can increase the service life like this, and this filter basket 50 in use for some time can be by its dismounting cleaning.
