Description

The biochemical waste water treatment unit

Technical field

The utility model relates to a kind of biochemical waste water treatment unit, belongs to the technical field that biochemical waste water is processed.

Background technology

Waste Water Treatment generally all is comprised of several processing series.Processing series is exactly the sequence of completing one or more Combination of Methods of certain particular procedure target.Processing target can have various classification, and processing target is determined in wastewater treatment, character (be called particle level compose) big or small by institute's material grains of removing usually.Divide according to this processing target, and comprise the processing of body refuse, can process series to mine wastewater and be divided into following four classes:

(1) particulate material is removed series.Method has method of sieving, gravitational separation process etc.

(2) suspended particle and colloid are removed series.That method comprises is concentrated, clarification, coagulating sedimentation etc.

(3) dissolved substance is removed series.Treatment process is a lot, comprises various chemical precipitation methods, absorption method, ion exchange method, membrane separation process, extraction process etc.

(4) body refuse is processed series.That method comprises is concentrated, dehydration (filtrations), drying etc.

Existing production wastewater treatment level of automation is not high, and treatment effect does not reach desirable effect.

The utility model content

The utility model purpose is to provide a kind of biochemical waste water treatment unit for the defective that prior art exists.

The utility model adopts following technical scheme for achieving the above object:

The utility model biochemical waste water treatment unit, by the grid well connect successively pump well, sanitary sewage equalizing tank, combined sewage pond, hydrolytic tank, contact-oxidation pool, flocculation tank, inclined-plate clarifying basin, pH is counter transfers pond, intermediate pool, strainer, detection water tank, middle pond and banish the pond, wherein banish open-channel meter be set on the pond.

Described strainer is made of more medium filter serial connection activated charcoal filter.

In described detection water tank, return line is set, is used for defective water is back to the combined sewage pond.

The utility model biochemical waste water treatment system Real Time Monitoring and each wastewater treatment stage of regulation and control, level of automation is high, and water treatment effect is desirable.

Embodiment

As shown in Figure 1, the utility model biochemical waste water treatment unit, by the grid well connect successively pump well, sanitary sewage equalizing tank, combined sewage pond, hydrolytic tank, contact-oxidation pool, flocculation tank, inclined-plate clarifying basin, pH is counter transfers pond, intermediate pool, strainer, detection water tank, middle pond and banish the pond, wherein banish open-channel meter be set on the pond.

Described strainer is made of more medium filter serial connection activated charcoal filter.

In described detection water tank, return line is set, is used for defective water is back to the combined sewage pond.

A) sanitary sewage (each compartmentation manure pit processed waste water of dining room waste water and factory) is introduced between the grid of the sanitary sewage equalizing tank front end in waste water station, removes foreign material through the rotary type grid and flows into pump well;

B) be promoted to sanitary sewage equalizing tank (being provided with air stirrer) through pump after the inflow pump well, then be promoted to combined sewage pond (being provided with mechanical stirring device) through pump, materialization waste water also pumps into the combined sewage pond of waste water station;

C) mechanical stirring device is established in the combined sewage pond, prevents the suspended substance precipitation, regulates simultaneously the waste water water yield and water quality.

D) in the combined sewage pond, sewage is promoted in hydrolysis acidification pool through pump, and through after acidication, the biodegradability of waste water is improved, and pollutent obtains the part removal simultaneously.Then waste water enters in contact-oxidation pool, biological contact oxidation process belongs to biomembrance process, by the microbial film that is attached in elastic filler, waste water flows in the elastic filler of up/down perforation, extensively contact with microbial film, under the condition of aerobic, through the effect of the bacteria metabolism function on microbial film, organic pollutant in waste water is removed, and waste water is purified.

Biochemical treatment adopts hydrolysis to add the biochemical processing process that contacts oxidation style.

For guaranteeing treatment effect, effective duration of contact of acidication was greater than 3 hours.The filler of amphimicrobe apposition growth is set in the pond, amphimicrobe is grown on 3 D elastic filler, can form the sludge blanket that is similar to the suspension type Sludge Bed after biofilm, waste water is through the packing layer after biofilm, and the pollutent that contains in water is consumed by the metabolic function of microorganism and degraded or adsorbed from water and separate by the adsorption of microorganism species.

The catalytic oxidation district is a kind of take biomembrance process as main, has the biological treatment device of activated sludge process concurrently, provides oxygen source by gas blower, and the organism in this device is purified water quality by Institute of Micro-biology's absorption, degraded.For guaranteeing treatment effect, effectively require greater than 15 hours duration of contact.Adopt 3 D elastic filler, the gas distribution in catalytic oxidation district adopts the pore type aerator.The further denitrogenation of mixed-liquor return.

For guaranteeing the normal steady running of biochemical treatment line, before formally putting into operation, must adopt by the biochemical treatment line synchronous dynamic cultivation method that microbial film is cultivated and tamed.Under normal production status, the active sludge effective storage life is not less than 3 years.Under normal production status, elastic filler and padding support frame effective storage life are not less than 10 years.The elastic filler bracing frame adopts epoxy zinc rich primer+epoxide coal bituminous coating to carry out rotproofing.

E) add calcium hydroxide in the coagulation reaction tank of contact-oxidation pool water outlet, Fe+, PAM carry out coagulating sedimentation, after the settling tank solid-liquid separation, waste water through the anti-accent of pH value after, drain into intermediate pool.

F) for removing suspended substance (being mainly the bacterium corpse), the total phosphorus in the oxidation pond water outlet, guarantee qualified discharge, rear class arranges chemical dephosphorization technique.

G) water of intermediate pool flow to monitoring water tank through after multi-medium filtering and activated carbon filtration, and online monitoring instrument is set in monitoring water tank, and instrument detects pond in qualified rear inflow, and process again in the defective combined sewage pond of being back to.The more medium filter suspended substance that removes in the rear waste water of biological treatment, activated charcoal filter is used for reducing the COD content in waste water, is designed to carbon leaching material.Strainer filters speed per hour should be too not fast, should adopt automatically and control less than 10m/h, by the unlatching of PLC time variable control operated pneumatic valve, close, completes operation or back flushing.

H) the qualified water overflow of monitoring water tank enters middle pond, and a part of water in middle pond is as the former water of rear class intermediate water reuse system; Part overflow to the pond of releasing effluxes through after open-channel meter;

I) mud in settling tank enters in the mixing sludge pond.

The above is only preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
