Description

The Sewage from Ships treatment unit

Technical field

The utility model relates to a kind of environmental protecting device, particularly a kind of inland navigation craft sewage treatment unit.

Background technology

Along with the enhancing of people's environmental consciousness, the processing of daily life sewage is more and more caused people's attention.At present the treatment process of sanitary sewage is similar, generally all passes through barrier, homogenizing, acidication, and the catalytic oxidation degraded, is disinfected process such as back qualified discharge at secondary sedimentation.

Processing to sanitary sewage on the boats and ships has had special waste disposal plant now, though such waste disposal plant can be realized qualified discharge with sewage, and the following defective of ubiquity:

One, Zhuan Zhi structure is not quite reasonable, causes wastewater treatment efficiency not good;

Two, device has used the aerators such as oxygen machine or blower fan that expose to the sun to provide oxygen for biological aerobic processes, it highly is restricted on the boats and ships because device is installed in, the stroke of air in sewage that causes aerator to produce is shorter, makes aeration insufficient, and airborne oxygen is difficult for by bio-absorbable; On the other hand, because aerator adopts micro-pore aeration, micropore on the aerated conduit is easy to be stopped up by the dregs in the sewage, and micropore is not easy to cleaning, thereby aeration is affected, and the cost of oxygen machine and blower fan is higher owing to expose to the sun, so increased the manufacturing cost of Sewage from Ships treatment unit;

Three, drug disinfection, disinfection by ultraviolet light sterilizer or electronic sterilization sterilizer are adopted in the draining sterilization, drug disinfection now is eliminated gradually, and the fluorescent tube of disinfection by ultraviolet light sterilizer is short work-ing life, and maintenance is inconvenient, and film is easily given birth in the fluorescent tube the inside, influences sterilization effect; The electronic sterilization sterilizer is because works better starting slow (with the wet-pit synchronous initiation) makes disinfection not reach emission request;

Four, the device appearance volume is big, and overall weight is big, is unfavorable for transportation, installation and the maintenance of device.

Now also have and adopt of the processing of advanced technology, in CN2846290, disclose the utility model that a kind of name is called " Sewage from Ships treatment unit ", though it can improve the effect of sewage disposal to Sewage from Ships.But it also has the following disadvantages: it is that employing is split type, when ship's navigation, can influence its use properties; It is by manually pulverizing the thick thing piece in the mesh filter funnel, and its manipulation strength is big, is difficult for pulverizing, and causes the mesh filter funnel to stop up easily; It enters aeration tube with the water of sedimentation and filtration ditch by the blowdown return line with ejector and carries out aeration, when the blowdown return line stops up, cause aeration insufficient, the time to the sedimentation and filtration ditch aeration, because water does not filter the back in sterilization through filtering layer, can reduce the water quality of discharge water like this; Most importantly it carries out disinfection by the electromagnetism sterilizer, though can reach the disinfectant purpose, it can not deodorizing, its electromagnetism sterilizer is connected in series with drainage pipeline, both can influence emission effect, and be shortened the work-ing life of electromagnetism sterilizer, owing to pipeline configuration influences sterilisation effect.

Summary of the invention

The purpose of this utility model just provides a kind of compact construction, reliable, sterilization, sterilization and thoroughly reaches transportation, Sewage from Ships treatment unit easy to installation and maintenance.

The purpose of this utility model is achieved through the following technical solutions, it is a kind of Sewage from Ships treatment unit, comprise into sewage mouth, casing, reticular filter, the primary deposition chamber, aeration tube, the secondary sedimentation filtering basin, sterilization pool catchments, water shoot and sludge discharging port, wherein, advance the sewage mouth successively by being arranged on the intravital reticular filter of case, the primary deposition chamber, the secondary sedimentation filtering basin, the sterilization pool that catchments is communicated with water shoot, it is characterized in that: be provided with ozonation aerated head in the sterilization pool that catchments, ozonation aerated head is connected with ozonateur on being arranged on casing by copper pipe; Adjacently between primary deposition chamber and secondary sedimentation filtering basin be provided with two aerobic biofilters that water outlet and water-in form high low head, be provided with aeration tube in the primary deposition chamber, the inlet mouth of this aeration tube is connected with air compressor on being arranged on casing, is connected with sludge discharging port with blowdown dredge pump on being arranged on casing by pipeline in the bottom of primary deposition chamber, biological filter and secondary sedimentation filtering basin.

The utility model is work like this: the sanitary sewage on the boats and ships enters the thick thing piece of filtering in the reticular filter by advancing the sewage mouth, enter primary sedimentation pond through the sanitary sewage of just filtering and carry out abundant aeration, biology in the sewage can be survived, sewage behind the aeration is entering aerobic biofilter except that the organic impurity in anhydrating, removing water behind the impurity enters the secondary sedimentation filtering basin again and carries out entering the sterilization pool that catchments after the essence filter, the ozone that produces by ozonateur carries out thorough disinfection by the ozonation aerated head that copper pipe is transported in the sterilization pool that catchments to the water in the pond, deodorizing is at last by the water shoot qualified discharge.In treating processes,, mud can be focused on owing to all be connected with sludge discharging port in each filter tank by pipeline.

Owing to adopted technique scheme, the utlity model has following advantage:

1, it carries out disinfection by ozone, makes sterilization, sterilization more thorough, can also deodorizing, obviously improved draining water quality;

2, it is an integral body, makes compact construction, easy to installation and maintenance, ship's navigation the time, make reliable;

3, by stirring automatically, pulverize thick thing piece easily, avoided the reticular filter obstruction;

4, provide aeration gas by air compressor, make aeration more abundant;

5, it can also make the sanitary sewage water quality after the processing reach " integrated wastewater discharge standard " GB8978-1996 of country and " Pollution From Ships thing emission standard " GB3532-83 sanitary sewage first discharge standard, intestinal bacteria M.P.N geometrical mean≤250/100mL, total suspended solid SS≤50mg/L, five-day BOD BOD5≤50mg/L, pH value scope 6.0～8.5.
