As far back as 1912, sewage was contained in vial by Clarke (Clark) and Gage (Gage), tests.They find to the long-time aeration of sewage, there will be mud in vial, water quality also be improved significantly.They find further, and those are not had wash clean and is attached with the bottle of mud as sewage aeration experiment, wastewater treatment efficiency is better.The mud that they claim oneself growth this is " active sludge " (Activated Sludge).The main component of this kind of active sludge is exactly zoogloea, and zoogloea has very strong absorption, the ability of oxidation of organic compounds, has good settlement action.
In the present embodiment, the pillar pipeline 22 that this gas pipe line comprises such as circular ring-type main pipeline 21 and is evenly distributed on this ring-type main pipeline, this pillar pipeline 22 is at least 3, such as 4; Wherein this ring-type main pipeline 21 is provided with the port (not shown) for input air, and ring-type main pipeline 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 is emerged, and so can make the air filled cavity of output and more waste water, strengthens the effect of sewage disposal.
Specifically, air enters into each pillar pipeline 22 from ring-type main pipeline 21, and enters sewage from the end of pillar pipeline 22 with the form of tiny bubble, adds 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 with sewage, fully contact, 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, form carbonic acid gas and water, the propagation procreation of part supply self.So, dirty organic pollutants is degraded and is removed, and active sludge itself is multiplied growth, and sewage is then purified process.
In the present invention, the design volume of slop pail 10 should be relevant to the sewage volume entered, and is pre-designed, therefore there will not be flooding problems.The useful volume of slop pail 10 should consider 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 that this Domestic sewage pretreatment unit is used to the sewage of about 3 tons/day that process number is 1 family's discharge of 4 people, so, the useful volume of this device can be 3-4 cubic meter, if the radius of slop pail is 1 meter, so its height should be 1-2 rice, and the factor of above-mentioned consideration plays fine setting to the concrete size of staving.
Filter basket 50 is arranged on the below of rising pipe by the present invention, and its shape is consistent with the staving of size and slop pail 10, if such design makes there have been some impurity in the sewage entered, those impurity can be filtered basket 50 and retain, and the sewage entering into slop pail bottom has lacked these impurity, the effect that itself and air contact are managed will be better.In addition filter basket 50 of the present invention is arranged on the top of rising pipe 12, to avoid the foreign material such as the particle of gathering in filter basket 50 to flow out from pipeline 12 together with water outlet, ensures the cleanliness factor of water outlet.In the present embodiment, this filter basket 50 is lower than the upper limb of this guide shell 30, and that is, the sidewall of this guide shell 30 have passed through this filter basket 50.Filter basket 50 can be made up of corrosion-resistant material, such as resene, can increase the service life like this, and this filter basket 50 can be dismantled in use for some time and clean.
