A kind of multi-functional sewage process well
The utility model relates to sewage-treatment plant, specifically refers to a kind of multi-functional sewage process well.
Along with industrial development, the increasing pressure of city water resource shortage is large, and maintaining or recover the good water environment in city and even basin, is the effective way of sustainable utilization of water resource.Therefore, sewerage treatment and regeneration are significant.And the treatment for reuse of sewage also reduces quantity of wastewater effluent, reduces urban sewage load while substituting clean water source, there is the water yield stable, hydrophobic apart from the feature such as short, water producing cost is low, significant to building a resource-conserving and environment-friendly society.
Existing sewage water treatment method normally by sewage collecting in specific equipment, deposit a period of time in a device, the deposition of solids in sewage got off, post-depositional clean water overflow enters downstream unit.The electrodeposition substance that density can only be greater than water by this method gets off, and cannot isolate the material that density is less than water; Effluent quality is poor simultaneously, and follow-up water treatment technology difficulty is large.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of multi-functional sewage process well that effectively can be separated the solid matter of various density in sewage for the present situation of prior art, thus ensure effluent quality, reduces follow-up water treatment technology difficulty.
The utility model solves the problems of the technologies described above adopted technical scheme: this multi-functional sewage process well, comprise sewage reservoir, it is characterized in that described sewage reservoir is enclosed construction, described sewage reservoir is provided with grid sewage-removing machine, the water inlet of described grid sewage-removing machine connects the water inlet of described sewage reservoir, the delivery port of described grid sewage-removing machine is communicated with the dislodger of described sewage reservoir, and described dislodger is provided with pure water inlet, is also provided with the dredging tube be communicated with bottom described dislodger in described sewage reservoir; The top of described sewage reservoir is provided with steam vent.
In such scheme, described grid sewage-removing machine can be arranged on outside sewage reservoir, and preferably, can be provided with grid area in described sewage reservoir, described grid sewage-removing machine is arranged in this grid area.
As improvement, litter collection bag can be provided with in described storage tank, the sewage draining exit of the described grid sewage-removing machine of the airtight connection of opening of described litter collection bag.By litter collection bag collect grid sewage-removing machine interception under suspension or solid particulate matter, periodic cleaning, effectively prevent the blocking of grid sewage-removing machine, and easily operates.
In above-mentioned each scheme, post-depositional water purification with the mode effluent sewerage pond of overflow, also can be extracted out by water pump.Described water pump can be arranged on outside sewage reservoir, preferably, also can be provided with lifting zone in described sewage reservoir, is provided with the water pump for the water outlet after process being extracted out described dislodger in described lifting zone.Described water pump can be lift pump or submersible sewage pump preferably.
The bottom design of described dislodger can be pyramidal structure by the conveniently collection of silting.
As improvement, described sewage reservoir can comprise pond body and the buckle closure well lid at Chi Tishang, and described well lid is standard inspection well cover.This structure can use by supporting municipal sewer, not only good sewage processing effect, and the blocking avoiding sewer, and the rubbish filtered out also easily is cleared up.
Compared with prior art, the utility model is by the setting of grid sewage-removing machine, effectively can be separated the foreign material that treatment sewage Midst density is less than water, also can remove according to grid pore size the large particulate matter that a part of density is greater than water, ensure that effluent quality, alleviate follow-up water treatment load, solve the susceptible to plugging problem of follow-up relevant device.Multi-functional sewage process well provided by the utility model is especially suitable as the front-end processing system of Small Sewage Treatment Equipment, or supporting municipal sewer uses, and thoroughly can solve the blockage problem of municipal sewer.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, this multi-functional sewage process well comprises:
Sewage reservoir 1 is enclosed construction, and comprise pond body 17 and the well lid 18 of buckle closure on pond body 17, the well lid 18 in the present embodiment is standard inspection well cover.Pond body 17 is provided with water inlet 14, and top is provided with steam vent, steam vent is connected with stack 15; The inner chamber of sewage reservoir 1 is divided into grid area 12, dislodger 11 and lifting zone 13, and wherein the bottom of dislodger 11 is pyramidal structure.The sidewall of dislodger 11 is also provided with pure water inlet, in pure water inlet, is connected with pure water pipe 16.
Grid sewage-removing machine 2, is arranged in grid area 12, and for tackling large particulate matter, especially density is less than the large particulate matter of water density.Its water inlet 21 connects the water inlet of sewage reservoir, and its delivery port 22 is positioned at the top of dislodger 11, and sewage, after grid sewage-removing machine tentatively filters, enters in dislodger 11 via its delivery port.Grid sewage-removing machine 2 can select as required of the prior art any one, preferably, screw grid spotter or rotary drum grid spotter can be selected.
Dredging tube 3, be arranged on sewage reservoir 1, its bottom inlet is plugged in the bottom of dislodger 11, and its top exit connects extraneous spoil disposal pipeline (not shown).
Water pump 4, is arranged in lifting zone 13, for being extracted out by the water purification after process in dislodger.
Litter collection bag, not shown, be placed in storage tank 12, the sewage draining exit of the airtight connection grid sewage-removing machine 2 of opening of litter collection bag.
The operating principle of this multi-functional sewage process well is described below:
Treatment sewage enters the water inlet of grid sewage-removing machine after entering from sewage reservoir water inlet by pipeline, flow into before grid frame, and by grid filtration, dirt is dammed on grid face; After filtering out large particulate matter, enter in dislodger from the delivery port of grid sewage-removing machine, the Impurity deposition that the mud in water, grains of sand isodensity are greater than water gets off, and discharges via dredging tube 3; Water purification is sent from pure water pipe by water pump.
The rotary teeth buttress be arranged on grid sewage-removing machine central axis regularly turns round according to the time parameter set, clear up by the dirt blocking grid face and tackle, when scarfing cinder tooth plate takes off collection to grid frame summit dirt, being removed sticking to the dirt automatic scraping rotated on tooth plate by the scarfing cinder tooth plate on grid frame top again, dropping in litter collection bag from sewage draining exit.The litter collection bag of rubbish is filled with in periodic cleaning, litter collection bag new in replacement.
Below inspection well cover pond body being arranged on municipal sewer, with the well lid of inspection well cover original on road as pond body; Regularly open inspection well cover, the rubbish that this sewage treatment well process goes out can be cleaned out.
This multi-functional sewage process well construction is simple, reliable transmission, block dirty effective, can automatic operation, without the need to staff on duty; Especially the design of dislodger conical lower portion, just ensures that water inlet is through certain time of staying, bottom Impurity deposition to dislodger; And not easily by turbulent water, avoid deposit and roll at the bottom of pond.
