Abstract

The utility model relates to a sewage purifier which is composed of a fermentation chamber, a corrosion chamber, a filter chamber, etc. The organic pollutant and other harmful substances in the sewage are converted into the substances which are harmless to the water quality by using bacteria and microbes in the device, and thus the waste water reaches the stated discharge standard. The technology is suitable for civil residences, hotels, restaurants and the purification treatment of the sewage which is discharged in the industrial production. The device is designed to be a small unit or a system according to the use requirement.

Description

Sewage purification equipment

The utility model relates to a kind of sewage purification treatment facility that is used for.

In existing sewage disposal technology, often adopt methods such as aerated precipitation tank, septic tank, sand filter, filtering net to solve, generally adopt open-type, it is big all to have floor space, the maintenance clean difficulty, work-ing life is short, and disease is covered in polluted underground water source etc.

In human lives and activity in production, constantly cause pollution to natural water.Source of pollution are mainly from two aspects: the sewage that A. sanitary sewage---ight soil, washroom, bathroom, kitchen etc. produce; B. the sewage that some industrial sewage---food factory, dairy plant, Grain and Cooking Oil Processing Factory, slaughterhouse, leather factory, paper mill, textile mills etc. produce.Its pollutent mainly is organic substances such as some carbohydrate, lipid, protein, and their basic comprising element is C, H, O, N, S, P.In addition, this class sewage also may contain micro heavy (as Zn, Cu, Pb, Cr etc.) ionic pollutent.The utility model can carry out purifying treatment to above-mentioned sewage, makes it reach the emission standard of regulation.

In order to achieve the above object, the utility model adopts following technical scheme: in the housing of a sealing, be divided into proving room, corruption chamber, filtration chamber's three parts with dividing plate.The sewage that purifies enters proving room from water inlet pipe, flows to the corruption chamber by overflow port, enters the filtration chamber by hydraulic pipe then, discharges from rising pipe through the sewage that purifies at last.General in the sewage that contains organic pollutant matter, containing a large amount of simultaneously is the bacterium (the utility model mainly utilizes anerobe) of food with these materials.Under optimum condition provided by the utility model, bacterium is able to breeding rapidly, its quantity is pressed logarithmic growth, they just can consume a large amount of foods (being pollution substance) at short notice, these organic pollutants are changed into inorganic substance, as nitrate, carbonate, phosphoric acid salt, vitriol equimolecular inorganics simple in structure.This class inorganic salt or be dissolved in water perhaps get off as precipitate, also have the portion gas product to be thrown in the atmosphere in addition, as methane (CH ₄), carbonic acid gas (CO ₂), hydrogen sulfide (H ₂S) and hydrogen (H ₂) etc., in general these materials are harmless to water quality.

The utility model compared with prior art, advantage is obvious, it has the purification efficiency height, equipment volume is little, maintaining is simple, free from extraneous odour, polluted source not, advantages such as long service life.

Fig. 5 is that the utility model is installed example schematic.

A kind of embodiment of the present utility model is: referring to Fig. 1, in the housing (13) of sealing, be divided into proving room, corruption chamber, filtration chamber's three parts by dividing plate (14).Sewage enters proving room (1) from water inlet pipe (4), and contained bacterium carries out decomposing and fermenting to organic pollutant in the sewage, makes its organic substance that becomes colloidal state, emits heat energy simultaneously, and cleaner is heated up.Because organic substance proportion is little, float over top fermentation sewage and enter corruption chamber (2) from overflow port (5), bacterium is just indoor in corruption, with fermentation colloid thing is food, press the form of logarithmic growth, a large amount of breedings are got up, and organic pollutant is carried out further decomposed.It is horn-like then by vertically disposed hydraulic pipe (6) in the filtration chamber and the conducting tube (8) that communicates with it sewage to be sent into conducting tube bottom one-tenth, and the water strainer of surperficial perforate (7) enters filtration chamber (3) behind mechanical filter.Top, filtration chamber is occupied by the biofiltration bed (9) that suspends in water, and has one deck bacterial layer along filter bed monomer surface, thereby is referred to as the biofiltration bed.The biofiltration bed has two basic functions: bacterium can be carried out further the colloid organic pollutant and be decomposed on the one hand; On the other hand because this one deck constitutes (referring to Fig. 2) by the porous monomer, thereby this layer also plays the effect of mechanical filter, for the porous monomer, requires its specific surface area 〉=190M ²/ M ³, 90% of voidage 〉=contained volume, monomer material proportion＜1g/cm ³So far the organic pollutant in the sewage has been consumed 80～95%, and is broken down into inorganic salt and the gas harmless to water quality.Again through the filtration of filter screen shape rising pipe (10), purifying waste water just can be disposed to public sewer, river, river, lake, sea, farmland or underground by rising pipe, can also recycle again through advanced treatment at last.Gas is discharged from the set venting hole in the top of filtration chamber's shell (11).Center of top at housing is provided with an insulation cover (12), when opening, can observe three indoor dispositions at any time, can also get rid of mud from here.For the water that is subjected to micro heavy (as Zn, Cu, Pb, Cr etc.) ionic soil,, thereby adopt the utility model also can reach the purpose of purifying treatment because they are formation things of inorganic salt positive ion.

Because the mode that this sewage purification device adopts mechanical filter and biochemical treatment to combine, so it is few to handle the back residual sludge, under normal service condition, a set of equipment need not removed mud in 3～5 years, and can be equal to the life-span of buildings the work-ing life of equipment.

Another embodiment of the present utility model is: referring to Fig. 3, in this scheme proving room, corruption chamber are arranged in the housing, the filtration chamber places separately in the housing, and two housings link to each other with pipeline.This scheme can reduce the volume of single-piece housing, is convenient to make and install.

Another embodiment of the present utility model is: referring to Fig. 4, this scheme adopts horizontal type structure, and three chambers are placed respectively in the horizontal drum, to reduce whole height, increases filtration chamber's volume, improves decontamination effect improving.
