Abstract

A life waste water treating device belonging to the domestic sewage treatment field integrates anaerobic, filter and aerobic, wherein a cylindrical casing consists of an anaerobic area which is connected with an inlet pipe, an aerobic area which is connected with an outlet pipe and a filter area which communicates the anaerobic area and the aerobic area, wherein the aerobic area which is communicated with the air is a concentric connected annular oxidation ditch, the head part of the anaerobic area is a truncated cone structure, the space formed by the outside of the truncated cone of the anaerobic area and the bottom surface of the aerobic area is a filter area, the device organically integrates the biological treatment and the mechanical filtration as a whole, so the utility model not only has the advantages of small device cubage and high treatment efficiency, but also does not require to use any power, and the operation cost is much lower than the similar product of domestic and overseas. The sewage treated by the device can be discharged directly into river, lake and sea or irrigating farmland or infiltrating underground, so environmental pollution can not be caused. The utility model is applicable to the dispersed domestic sewage treatment for advanced hotel, villa quarter, medium station and small station along the railway line, mine and oilfield far from urban, etc.

Description

Sewage treatment unit

Technical field

The utility model belongs to the sanitary sewage disposal field, refers in particular to a kind of packaged unit of handling sanitary sewage.

Background technology

The compact apparatus of handling sanitary sewage has two kinds usually: " sewage purification device " that it is set forth just like Chinese patent CN93225082, the housing inner-use clapboard of its sealing is divided into proving room, corruption chamber and filtration chamber's three parts, principle is to adopt mechanical filter and the biochemical treatment mode that combines, main treating processes is the anaerobic biological process, the deficiency that exists is that processing efficiency is low, and volume is big; It two is as Chinese patent CN97207712 disclosed " sanitary sewage disposal integrated apparatus ", its collection anaerobe oxidation pond, aerobe oxidation pond, inclined-plate clarifying basin are one, filler all is housed in anaerobic pond, the Aerobic Pond, reduced obstruction, pass through the oxygenation of aeration basin with gas blower in the Aerobic Pond, strengthened aeration intensity, its principle is to utilize anaerobism to improve processing efficiency with the aerobic mode that combines, the deficiency that exists is dynamic consumption, has increased working cost and overhead charges.

Summary of the invention

The utility model adopts bio anaerobic and the aerobic mode that combines, not only processing efficiency height, and unpowered operation, and incorporate structure design guarantees that occupation area of equipment is few.The utility model is to implement like this: a kind of anaerobism, filtration, aerobic domestic sewage treatment device of integrating, it is characterized in that cylindrical shell is made up of the anaerobic zone that connects water inlet pipe, filtrating area three parts that connect the aerobic zone of rising pipe and connect anaerobic zone and aerobic zone, the aerobic zone that communicates with atmosphere is the concentric annular oxidation ditch that joins, the anaerobic zone head is frustum cone structure, and the round platform outside and the space that the aerobic zone bottom surface forms of anaerobic zone are filtrating area.

Anaerobic zone of the present utility model is separated into first septic tank, second septic tank and settling bath by dividing plate, and first septic tank all communicates by the spillway on the dividing plate with settling bath with second septic tank, second septic tank.

Characteristics of the present utility model are: the sewage treatment unit of carrying out a biological disposal upon and mechanical filter is combined into one; existing anaerobic treatment has nature to carry out the aerobic treatment of oxygen again; not only equipment volume is little; the processing efficiency height; and need not to adopt any power; only rely on waterhead to move; its working cost is compared much lower with similar products at home and abroad; sewage through this device processes; can directly enter rivers,lakes and seas or irrigated farmland or permeate the ground; can not cause environmental pollution, be suitable for senior guest's pipe; villa community; railway along the line in; small-sized station is away from the mine in city; oil fields etc. are the dispersive sanitary sewage disposal relatively.

Embodiment

Processed sewage at first enters first septic tank (21) the anaerobic zone (2) that head is frustum cone structure from water inlet pipe (1), in the short period (24-48h), produce the corruption reaction, make organic pollutant in the sewage become a kind of material of hemicolloid state, emit heat energy simultaneously, first septic tank (21) is heated up; The sewage that contains hemicolloid state organic pollutant, spillway (23) from dividing plate (22) enters second septic tank (24), (be generally 24h) at short notice, anerobe can be resolved into the organic pollutant that adds up to 30-40% the inorganic substance harmless to water quality, because the negative ion of heavy metal and the positive ion of inorganic salt can combine, therefore this equipment also has tangible decontamination effect improving to being subjected to the water of heavy-metal pollution; Sewage through after second septic tank (24) purification enters settling bath (27) through dividing plate (25) spillway (26), and in settling bath (27) bottom, current enter filtrating area (3) by conducting tube (28) to water-fast settling as silting; Because sewage has gas to produce in the anaerobic treatment process, the round platform head center of anaerobic zone (2) is provided with an equilibration tube (29) that communicates simultaneously with anaerobic zone first septic tank, second septic tank, settling bath, and the gas that produces in the anaerobic treatment process is discharged by the vapor pipe (4) at equilibration tube (29) slave unit top.

Filtrating area (3) is built-in with filler supporting plate (31), anerobe on the biofiltration bed has and adheres to density greatly, the organic pollutant that residues in the water is carried out high efficiency decomposition, purification rate can reach about 50%, a large amount of and the intensive hole that is furnished with on the filler supporting plate (31), when realizing biofiltration, again the water behind the biological decomposition being carried out one-time mechanical filters, water after the filtration enters the aerobic zone (5) that communicates with atmosphere by the hole that is arranged on the manhole (32) on anaerobic zone (2) round platform, be concentric anastomosing annular and carry out placement gravel in the oxidation ditch (51) in oxygen district naturally, to enlarge oxygen district face, water quality is further purified, and the water of discharging from water shoot (6) has reached national specified discharge standard at last.
