Description
Technical Field
The utility model relates to a sewage treatment field especially relates to rural domestic sewage, city domestic sewage, industrial sewage carry mark and reform transform the field, also can be applied to the emergency treatment in river course, the emergency treatment upgrade of pump station reforms transform.
Background
At the present stage, the main treatment difficulty of rural domestic sewage is that the flow rate is unstable all day long, the water is discharged for 20 hours in the morning, noon and evening, the proportion of the water occupied by the sewage discharge reaches 50% -80%, the requirement on the impact resistance of equipment is high, an adjusting pool and a pump station are needed, and the soil construction cost and the equipment cost are high.
Secondly, as residents in rural areas live in a scattered manner and rural drainage facilities are imperfect, a proper sewage treatment zone needs to be selected according to local conditions in the treatment process, so that the occupied area of sewage treatment equipment needs to be reduced as much as possible.
In the aspect of emergency treatment of the river channel, the city river channel is an important carrier for maintaining city ecological balance, optimizing city landscape and improving human living environment, and the dam on the river channel also causes the flowability of the river channel to be poor, so that in dry seasons, the static water body with insufficient self-purification capacity can flow out of the river channel only in flood season. Once serious pollution events such as blue-green algae outbreak, black and odorous, aquatic weed cluster and the like occur in the river channel, urban landscapes are hindered, urban images are destroyed, living and living conditions of residents along the river are affected, and living environment and ecological health of people are directly threatened.
The content of dissolved oxygen in river water is an important index for reflecting the pollution state of a water body, and the self-purification process of the river is reflected in the process of changing the concentration of the dissolved oxygen in the polluted water body. When dissolved oxygen exists in the water body, organic matters in the river water are decomposed by aerobic bacteria, so that the content of the dissolved oxygen in the water is reduced, the concentration is lower than a saturation value, and the oxygen in the atmosphere on the water surface is dissolved in the river water to supplement the consumed oxygen. If the organic matter content in river water is more, dissolved oxygen is consumed too fast, oxygen in the atmosphere is not available, and the dissolved oxygen in the water body is gradually reduced or even consumed completely, so that the balance of a water ecosystem is influenced. When the dissolved oxygen in the river is used up, the river can be in an anaerobic state, the decomposition of organic matters is converted from aerobic decomposition to anaerobic decomposition, the water quality is deteriorated, and even a black and odorous phenomenon occurs. At this point, the water ecosystem is severely damaged and cannot be restored by itself. Therefore, the dissolved oxygen plays an important role in the river water self-purification process.
The existing rural and emergency sewage treatment equipment is complex in equipment, large in occupied area, high in maintenance and operation cost, cannot be effectively applied to the field of rural and emergency treatment, is slow in effect, cannot deal with sudden environmental water pollution events, and cannot treat polluted water bodies in real time on the spot.
