Description
Technical field
The present invention relates to equipment for separating liquid from solid and technology field, specifically, design a kind of wastewater processing technology dress
It puts.
Background technology
For most of waste water of part industrial enterprise essentially from cutting, grinding, the process section of polishing, the COD of waste water is general
All over less than first discharge standard, but the pollutant in water is generally floated on containing grease, fines etc., and cause waste water direct
Discharge or reuse.
And traditional water technology is required to substantial amounts of civil engineering, constructing multifeed clarifier could be effectively by separation of solid and liquid.
It takes up a large area, the problems such as fixed investment is big is so that industrial enterprise is unwilling to carry out Environmental Inputs, and causes contaminated wastewater.
The content of the invention
The application provides a kind of device and technique for being related to cutting/grinding/glossing wastewater treatment, passes through apparatus
Functional combination, it is big to solve the problem of that existing wastewater processing technology takes up a large area fixed investment.
The application uses following technical scheme：Device by general technology order be broadly divided into dosing mixing, precipitation separation and
It is separated by filtration three parts.Precipitation separation is respectively equipped with mud chamber and sewage draining exit with the device being separated by filtration.Wherein, dosing mixes
Using pipeline mixing method, flocculating settling agent or heavy metal chelating agent are sufficiently mixed；Precipitation separation is using vertical sedimentation tank
Design；It is separated by filtration and combines carry out separation of solid and liquid using micro-filtration/ultrafiltration/nanofiltration/reverse osmosis one or more modes.
It applies the technical scheme of the present invention, due to carrying out rational technique using easy structure and conventional apparatus
Combination has the characteristics that applicability is wide, low-cost, installation is easy, it is simple to safeguard.It is particularly suitable for containing insoluble pollutant
Wastewater treatment.

Specific embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.It is bright that the present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The device and technique of the wastewater treatment of the present invention are used to handle the polishing waste water of certain ceramics factory.It is mainly contained in waste water
Ceramic material, lead powder, oils.The wastewater treatment equipment employs structure as shown in Figure 1.
Waste water is driven by pump in waste water inlet pipe 1-1, and flocculating settling agent PAM is driven by pump in medicament inlet pipe 1-2,
It is sufficiently mixed using dislocation parallel baffle mixing channel 1-B.The mixed precipitation room that gravity flow enters in precipitation separator 2 is 2-3.
Ceramic material, lead powder etc. form sludge settling into Ji Ni mud chambers 2-2, and are periodically discharged via collection mud sewage draining exit 2-1.Oils
It then floats and is enriched on the liquid level of mixed precipitation room, periodically manually drain.It precipitates isolated supernatant and passes through downflow weir 2-4
The cinder pocket 3-5 that liquid crosses liquid 2-5 and be flowed into naturally in filter separator 3 is crossed with overflow, still contains a small amount of pottery in supernatant
Porcelain pug via perforation sediment partition plate 3-4 barrier effect, and precipitate with cinder pocket 3-5 in, via collection slag sewage draining exit 3-1 it is regular
Discharge.After supernatant passes through perforation sediment partition plate 3-4, flat inorganic filter device 2-2 is submerged.External constant pressure Suction filtration device
Drainage is extracted out via filtering water discharge pipe 3-3 and collects storage, as Treated sewage reusing.Wherein, the tablet in the present embodiment
Formula inorganic filter device is to use effective filtration area 20 square of the aperture for 0.1 micron of oxidation aluminium material flat-plate separation film composition
The membrane module composition of rice.Meanwhile the filtering film component is configured with gas distribution formula air-floating apparatus, can further remove oil slick.
The COD of raw wastewater is 33mg/L, petroleum-type 750mg/L, turbidity 500mg/L, lead 0.48mg/L;Processed waste water
COD be 28mg/L, petroleum-type 28mg/L, turbidity 7mg/L, lead 0.01mg/L.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
