Background technique

In China, the rapid growth of population and industrialized rapid development, so that water environmental problems become increasingly tighter It is high.In recent years, water resources situation severe exacerbation, in most of rural area water source, the indexs such as ammonia nitrogen, COD, total phosphorus are different degrees of Exceeded, main source of the sanitary sewage as water pollution more attracts attention.

Modern sewage processing technique is divided by processing mode, can be divided into physical treatment, chemical treatment and biological treatment.It is raw Object contact oxidation method belongs to aerobic biological process for treating, and the biological contact oxidation pond in equipment is the key facility of biofilm One of, biofilm is the general designation of a major class biological treatment, and method mainly utilizes apposition growth in certain solid dielectrics Microorganism (i.e. biomembrane) carry out organic sewage processing.Biomembrane be by the aerobic bacteria of highly dense, anaerobic bacteria, amphimicrobe, The solid dielectric of the ecosystem of the compositions such as fungi, protozoan and algae, attachment is known as filtrate or carrier.Biomembrane is certainly Filtrate can be divided into lonely layer, aerobic layer, attachment water layer, flowing water layer outward.Its principle is that biomembrane adsorbs attachment water layer first Organic matter is decomposed by the aerobic organism of aerobic layer, is entered back into lonely layer and is carried out anaerobic decomposition, flows water layer then by the life of aging Object film is washed out to grow new biomembrane, and so on to achieve the purpose that purify sewage.

However, existing biological contact oxidation pond coefficient of oxygen utilization is low, organic removal rate is low, hydraulic detention time is long, accounts for The problems such as ground area is big, construction investment is high is emerged one after another, and removal impurity effect is not ideal enough, is often not able to reach discharge and is referred to Mark.

Utility model content

A kind of reinforcing two-stage bio-contact oxidation pond is provided the purpose of the utility model is to overcome the deficiencies in the prior art, Coefficient of oxygen utilization is high, organic removal rate is high, hydraulic detention time is short, occupied area is small, and construction cost and operating cost are lower, Conducive to promotion and implementation.

The technical solution of the utility model is as follows:

A kind of reinforcing two-stage bio-contact oxidation pond, including oxidation pond, oxidation pond is interior to be divided by vertically arranged partition The first oxidation vertical shaft in left side and the second oxidation vertical shaft on right side, there are gap in the lower end and oxidation pond bottom surface of partition, formed water Hole；Left end, the top of first oxidation vertical shaft are equipped with vertical baffle, and the lower end of vertical baffle extends to oxidation pond left wall to the left and formed Horizontal baffle, the lower end of vertical baffle are equipped with an arrangement water hole, and vertical baffle, horizontal baffle and oxidation pond left wall surround water distribution The left end in area, water distribution area is equipped with water inlet；In first oxidation vertical shaft, the multilayer vertical tube filler being superimposed up and down is equipped with below water distribution area Layer, vertical tube packing layer region is set as retained aeration area；The bottom of oxidation pond is set as the area Chu Ni, in the area Chu Ni bottom be equipped with by The emptying pipeline of left-to-right distribution, the right end for emptying pipeline stretch out outside oxidation pond, and aerator, aeration are equipped with above emptying pipeline Device is connected to the gas source outside oxidation pond；In second oxidation vertical shaft, it is set as clear water zone, catalytic oxidation area and slag stone from top to bottom Packing area, slag hardcore area lower section are the area Chu Ni, and the right side of clear water zone is equipped with water outlet, and catalytic oxidation area is equipped with suspension type group Filler is closed, slag hardcore area is equipped with slag hardcore.

The multilayer vertical tube packing layer uses two layers of vertical tube filler, and the vertical tube filler on upper layer and the vertical tube filler of lower layer are wrong Position setting, the vertical tube filler on upper layer and the vertical tube filler of lower layer pass through filler support and are fixed in the middle part of the first oxidation vertical shaft.

The suspended combined fillers round steel bracket, which is set up, to be fixed.

The slag hardcore is set up by Stainless-steel space grids and is fixed.

The aerator includes aerated conduit and multiple large-scale micro-hole aerators, and aerated conduit is arranged from left to right, The left end of aerated conduit stretches out oxidation pond and connects gas source, is evenly distributed with multiple gas vents on aerated conduit；Multiple large size micropores Aerator is arranged in parallel from front to back, and multiple gas vents point on the inlet end and aerated conduit of multiple large-scale micro-hole aerators It is not connected to.

The utility model has the beneficial effects that

The utility model includes oxidation pond, is divided into the first oxidation vertical shaft in left side in oxidation pond by vertically arranged partition Vertical shaft is aoxidized with the second of right side, there are gap in the lower end and oxidation pond bottom surface of partition, form water hole.The setting of water hole, makes The entire bottom of oxidation pond is obtained into the area Chu Ni of connection.Sewage enters water distribution area by equipment water inlet, passes through point of water distributing pore Stream effect, sewage equably flow downwardly into retained aeration area, and under the constraint effect of upper layer and lower layer vertical tube packing layer, water flow is vertical It flows downward；Meanwhile air is delivered in large-scale micro-hole aerator by Aeration fan by aerated conduit, since multiple large sizes are micro- Hole aerator is arranged in parallel from front to back, it is each large size micro-hole aerator surface semicircular in shape and disk body length it is larger, bubble energy It is enough evenly distributed in water, and is moved from bottom to top under the action of water pressure；Water flow and bubble flow on the contrary, in bubble Under agitaion, water flow becomes turbulent flow from laminar flow, and gas-liquid mass transfer effect also greatly improves, and the organic pollutant in sewage is micro- It is partially removed under the action of biology.

After sewage enters catalytic oxidation area, the microorganism in sewage is in slag hardcore and suspended combined fillers surface Apposition growth forms biomembrane；Under the action of biomembrane, most organic pollutants is oxidized decomposition in sewage, together When due to slag hardcore large specific surface area, porosity is higher, while serving as microbe carrier, also have filtering work With, can by sewage suspended material and remaining microorganism wadding body intercept, eventually by emptying pipeline device for transferring.
