Abstract
The invention discloses an environment-friendly zero emission treatment system for printing workshop sewage. The system comprises a sewage pool, a distillation retort, a condensation pipe, a settling pond, a sand filter, an anaerobic hydrolysis pool and a clean-water reservoir which are sequentially connected with one another, wherein a water pump is arranged on a pipeline used for communicating the sewage pool with the distillation retort; the collected sewage is delivered into the distillation retort from the sewage pool through the water pump; an electric heater is arranged at the bottom of the distillation retort; one end of the condensation pipe is connected with the top end of the distillation retort, and the other end of the condensation pipe is communicated with the settling pond. The system is reasonable in design, a distillation, settling and sand filtering process is adopted, the effluent of the treated wastewater is clear and transparent, the water quality meets the requirement of production water supply, the sewage treatment system is low in operating cost, and the aims of saving water resources, protecting the environment and reducing the enterprise cost can be achieved.
Description
Technical field
The present invention relates to a kind of Sewage treatment systems, be specifically related to the environmental protection zero-discharge treatment system of machine room's sewage.
Background technology
The printing device of gravure printing machine comprises standard type and top nip drum cartridge type printing device, and the former is comprised of plate cylinder and impression cylinder.Wherein, plate cylinder is round shape, and copper coating, as plate, then, by engraving or photoetching, forms sunk picture and text at cylinder surface.The plate cylinder of gravure printing machine directly immerses in ink tank, ink under running up fills up plate cylinder soon, then through scraping blade, the ink of forme surface blank parts is scraped off, the ink of remaining picture and text groove part, the roll extrusion of process impression cylinder on paper or other stock, becomes printed matter by ink transfer.
Ink tank will clean thoroughly in printing process, due to ink in printing process and paper powder, paper hair, dust, the impurity such as mineral substance mixes the surface that is present in rubber roll, and ink is oil-soluble, paper powder, paper hair, the impurity such as dust is water miscible, mineral substance is that You Heshui cannot dissolve, and they are present on rubber roll with the state mixing, and must be to coordinate by the principle of emulsification with ink sanitising agent and water, form water-in-oil and oil-in-water state, clean be present in ink and the paper powder on rubber roll, paper hair, the material such as dust.Therefore in offset printing process, use ink sanitising agent be must and frequently, each clean printing seats ink all can produce sewage, the composition of sewage has comprised ink sanitising agent, water, ink, paper powder, paper hair and mineral substance etc., color presents the color of ink, and this sewage is toxic, very large on the impact of environment, if do not process or deal with improperly, can cause severe contamination to environment.
Summary of the invention
The object of this invention is to provide that a kind of running cost is cheap, can be used as the Sewage treatment systems for machine room of process water recycle after sewage disposal.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
The environmental protection zero-discharge treatment system of machine room's sewage, comprise connected successively sewage lagoon, retort, prolong, settling tank, sand filter, anaerobic fixed film reactor and clean water basin, the pipeline that described sewage lagoon communicates with retort is provided with water pump, and this water pump is delivered in retort from sewage lagoon collecting the sewage coming; The bottom of described retort is provided with electric heater, one end of prolong and retort top be connected, the other end communicates with settling tank.
On the basis of technique scheme, above-mentioned retort is also connected with defoamer hold-up vessel.
As improvement of the present invention, above-mentioned prolong lower end is provided with cooling fan.
In above-mentioned sand filter, be equipped with filter sand.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention is reasonable in design; adopt distillation, precipitation and sand filtration treatment process, waste water after treatment water outlet is as clear as crystal, and water quality meets the requirement of water of productive use; operation of sewage disposal system is with low cost, can reach the object of saving water resource, protection of the environment, reduction enterprise cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the environmental protection zero-discharge treatment system of machine room's sewage, comprise connected successively sewage lagoon 3, retort 1, prolong 4, settling tank 6, sand filter 7, anaerobic fixed film reactor 8 and clean water basin 9, described sewage lagoon 3 is provided with water pump with the pipeline that retort 1 communicates, and this water pump is delivered in retort 1 from sewage lagoon 3 collecting the sewage coming; The bottom of described retort 1 is provided with electric heater 2, one end of prolong 4 and retort 1 top be connected, the other end communicates with settling tank 6.Described retort 1 is also connected with defoamer hold-up vessel.Prolong lower end is provided with cooling fan.In described sand filter 7, be equipped with filter sand.
In actual moving process, water pump is delivered in retort 1 from sewage lagoon 3 collecting the sewage coming, can be except oiliness impurity in removal ink after froth breaking and distillation processing, after settling tank 6 precipitations, can remove the impurity such as silt particle, sewage after precipitation enters sand filter 7, after the filtration of different-grain diameter filter sand, absorption, some poisonous impurity can be by Ex-all; After filtering, water enters anaerobic fixed film reactor 8 again and further removes organic impurity, and the water after purification reaches emission standard, then flows into clean water basin 9 as process water.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that Bian has used method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
