Abstract

The utility model provides an energy-saving filtering type biosorption municipal sewage treatment system, which comprises a precipitation basin, a cinder and slag filtering basin, a biological cleaning basin and a winter evergreen aquatic plant cleaning basin. Sewage is precipitated in the precipitation basin and then overflowed into the cinder and slag filtering basin. Drain holes are arranged at the middle and lower parts of a partition wall between the basin and the biological cleaning basin. Sewage filtered flows to the biological cleaning basin through the drain holes. Overflow holes are arranged on a partition wall between the biological cleaning basin and the winter evergreen aquatic plant cleaning basin. Sewage cleaned in the biological cleaning basin flows to the winter evergreen aquatic plant cleaning basin through the overflow holes. Sewage is completely cleaned in the winter evergreen aquatic plant cleaning basin and then drains to river or is used as recycled water through drain holes on the other wall of the plant cleaning basin if sewage comes up to the national emission standard. With simple structure, low construction cost and sewage treatment cost, the energy-saving filtering type biosorption municipal sewage treatment system does not consume electric energy and can effectively clean the municipal sewage or the industrial sewage, thereby having high application and spread value.

Description

The biological absorption of energy-saving filtering type urban sewage treatment system

Technical field

The utility model relates to a kind of sewage disposal technology, is specifically related to the biological absorption of a kind of energy-saving filtering type sewage disposal technology.

Background technology

At present, known urban sewage treatment technology cost cost height, processing costs height, consuming electric power and purifying water body effectively.

Summary of the invention

The utility model aims to provide a kind of biological absorption of energy-saving filtering type sewage disposal technology of clarifying urban sewage effectively.

The technical solution adopted in the utility model and embodiment are: sewage enters settling tank through the municipal effluent water shoot, silt in the sewage etc. sinks to bottom the settling tank, settling tank and cinder, one row's spillway hole is arranged at the partition wall top in slag filtration pond, filtering net is arranged in the spillway hole, filtering net can prevent that the suspended substance in the sewage from entering filtering basin, sewage flows into cinder through spillway hole, the slag filtration pond, cinder, slag contains the various active component, loosely organized, specific surface area is big, can adsorb the heavy metal in the sewage effectively, ammonia, nitrogen, phosphorus and other impurity, various dirts such as nutrition; There are many water vents the middle and lower part of biopurification pond and filtering basin partition wall, water after the filtration enters the biopurification pond through water vent, various microbially decontaminate water bodys are arranged in the treating pond, dirt bed is arranged at bottom, biopurification pond, be implanted with heavy waterplant on the dirt bed, be implanted with duckweed, Herba Eichhorniae on the treating pond water surface, heavy waterplant, duckweed, Herba Eichhorniae be the dirt in the planar water and absorb nutritive substance in the water body effectively, and water body is further purified; Summer, sewage just reached state emission standard after the biopurification pond purifies; Biopurification pond and winter evergreen aquatic plant purification pond wall on the spillway hole of many flat rafts is arranged, water flows into evergreen aquatic plant purification pond in winter through spillway hole, dirt bed is arranged at bottom, plant purification pond, winter, evergreen cold-resistant waterplant was planted on earth, waterplant is the various dirts in the adsorbed water body effectively, absorb the various nutritive substances in the water body, water body is purified fully, reach state emission standard.Water used during the spillway hole of water after the purification on another headwall in aquatic plant purification pond discharged or done.

But the mud periodic cleaning in the above-mentioned settling tank.

The section of above-mentioned filtering basin is trapezoidal, and is shallow by settling tank side, dark by biopurification pond side, and the cinder in the filtering basin, slag absorption dirt can regularly replace when saturated.

Duckweed, Herba Eichhorniae in the above-mentioned biopurification pond are regularly salvaged, and make Herba Eichhorniae, duckweed in the biopurification pond keep suitable density, and water body can obtain certain solar radiation, guarantees that the heavy waterplant at the bottom of the pond can normal growth.

The beneficial effect that the utility model produces is: cost is low, low, the not consuming electric power of cost of sewage disposal, and clarifying urban sewage, industrial sewage effectively, energy-saving and emission-reduction are significant, have the excellent popularization using value.

Description of drawings

Fig. 1, Fig. 2 are the utility model structural representations.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1, Fig. 2 shows the biological absorption of a kind of energy-saving filtering type urban sewage treatment system structure, comprises municipal effluent water shoot 1, settling tank 2, the partition wall 3 of settling tank and filtering basin, spillway hole 4 on the partition wall, filtering basin 5, cinder, slag filtration layer 6, the partition wall 7 in filtering basin and biopurification pond, the water vent 8 that the filtering basin middle and lower part is many, biopurification pond 9, the dirt bed 10 for the treatment of pond bottom, the heavy waterplant 11 that grows on the dirt bed, the water surface 12, the duckweed that grows on the water surface, Herba Eichhorniae 13, spillway hole 14 on biopurification pond and the winter evergreen aquatic plant purification pond partition wall.

In Fig. 2: the water in biopurification pond enters evergreen aquatic plant purification pond 2 in winter by spillway hole 1, and the winter of planting on the dirt bed 3 for the treatment of pond bottom, the earth, cold-resistant evergreen waterplant 4, the water vent 5 of water on another headwall for the treatment of pond after purifying were discharged.
