Description
Technical Field
The invention belongs to a sewage treatment device, and particularly relates to an oil field oily sewage biological treatment device.
Background
A common treatment process for treating oily sewage in an oil field comprises the following steps: oilfield produced raw water → precipitation → air flotation → biological treatment → solid-liquid separation → first stage filtration → recycling. The biological treatment process is a process for removing emulsified oil particles and organic suspended matters in sewage by using microorganisms, and is usually actually completed by a group of biological ponds. The biological tank generally comprises a tank body, a biological carrier and an aeration system. The existing biological pool is basically characterized in that a filler frame and an aeration system are fixed in a pool body, and fillers used as biological carriers are hung in the filler frame and evenly distributed in the whole pool. Because the oily sewage treatment capacity of an oil field is generally more than 1 ten thousand square per day, the specific structure of the oily sewage treatment system is that a concrete masonry pool body with the width of 4-5 meters and the length of dozens of meters is generally adopted, an aeration pipeline is fixedly laid at the bottom of the pool body, a main pipeline led out from the top of the pool is connected with a plurality of branch pipelines which are uniformly distributed at the bottom of the whole pool, and aerators are uniformly and densely distributed on the branch pipelines; the steel or nonmetal filler frame of cell body comprises upper and lower two-layer of the same structure, and every layer comprises the many round bar peg of perpendicular equipartition with the girder steel between the many parallel steel crossbeams of both ends fixing the level equipartition on the pool wall and the girder steel, and the upper strata is not higher than the liquid level, and the lower floor has certain distance above the aerator and with the aerator, hangs full filler cluster perpendicularly between upper and lower layer, and the filler cluster generally comprises on a rope for multiunit pompon fibrous group cluster uniformly cluster, and the both ends of rope are fixed respectively on two-layer round bar peg about the filler frame.
When the device works, the tank body is filled with water to be treated, and the water stays in the tank for a certain time to fully react with microorganisms in the tank and separate impurities; impurities are adsorbed on the filler or sink to the bottom of the pool. The long-time accumulation, the filler and the bottom of the pool are accumulated with a large amount of silt to seriously affect the water treatment effect, lead to the damage of the filler, need to replace the filler and clean the bottom of the pool. Some of the existing biological ponds are provided with sludge discharge pipelines at the bottom of the pond, and a main pipeline is led out from the side wall close to the bottom of the pond and connected with a plurality of branches to be distributed at the bottom of the pond.
The biological pond is replaced with filler, and the operation of cleaning sludge at the bottom of the pond is a great project. Because of difficult dredging, the biological pond generally operates for 5 to 10 years to carry out one-time dredging, and because of long operation time during dredging, most of the filling materials in the pond fall off or break and are accumulated at the bottom of the pond, and the filling ropes are wound together, so that the manual cleaning difficulty is too large; the upper layer of a filler frame and the lower layer of the filler frame are removed and destroyed when the filler is cleaned and replaced every time in the existing biological tank, the filler which is full of sludge can be taken out by using a motor excavator device, the bottom of the tank is thoroughly cleaned, and the aeration pipeline and the sludge discharge pipeline which are densely distributed at the bottom of the tank bring great difficulty to the desilting operation. Especially, the biological pond is often that the multiunit is arranged side by side together, exceeds ground more than 3 meters in addition, and artifical desilting can't be realized, must put into the pond with small-size mechanical equipment and clear up, and the oily anaerobism silt accumulation in the pond, and the construction operation risk is big.
In the working process of the biological pond, sporadic filler strings are difficult to fall off. When the filler drops a lot, the whole working efficiency of the biological tank is influenced, and the aeration system is also influenced by the falling filler accumulated at the bottom of the tank; in addition, the aeration system is fully distributed in the pipeline and the aerator at the bottom of the tank, so that the failure caused by the failure of individual components is difficult to avoid; the existing biological pond can not be partially replaced or maintained, and only the whole biological pond can be replaced and cleaned after being shut down.
The sludge discharge pipelines of the existing biological pond are all led out from the side wall of the pond body, and the leakage is easy to occur at the pipeline wall-penetrating joint, so that the number of the pipeline wall-penetrating pipelines of the existing biological pond is reduced as much as possible. Generally, only one main pipeline of the sludge discharge pipeline is led out and distributed to the whole pool bottom, a single path is dozens of meters long, the pool bottom is difficult to have a space to form a slope, and the sludge discharge is difficult.
One side of the biological tank close to the water inlet and one side of the outlet are different in pollutant concentration, and the filler attachment amount, the tank bottom deposition amount and the required aeration amount are different, so that different aeration amounts and different dredging time intervals can be adopted according to different conditions of different positions of the biological tank, and the efficiency of the whole biological tank can be better exerted. The existing biological pond sludge discharge and aeration system is integrated and cannot be flexibly controlled in different areas.
