Problems solved by technology

However, the cost of biological and chemical methods is high, the treatment capacity is small, and the quality of effluent water is still difficult to meet the requirements
Especially in the prior art, only large-scale treatment of domestic wastewater is often possible, while large-scale treatment of oily wastewater or industrial wastewater is still difficult

Embodiment Construction

[0022] Referring to the accompanying drawings, reflecting a specific structure of the present invention, the sewage regeneration cycle treatment system includes a heating furnace 6, a first treatment unit and a second treatment unit;

[0023] The first processing unit includes an inner water tank 4 placed on a heating furnace 6, the inner water tank 4 is a cylinder, the heating furnace 6 is a crescent-shaped elongated body, and the inner water tank 4 is set in the heating furnace 6 in the crescent-shaped groove; the heating furnace 6 is provided with a fuel addition port 8 and a ventilation hole 9.

[0024] Oily waste water is injected into the inner water tank 4 and sodium hydroxide and activated clay are added. The sodium hydroxide makes the water turbidity significantly lower, and the activated clay makes the sewage more pure. The heating furnace 6 makes the oily waste water in the inner water tank 4 high-temperature distilled. , so that the water in the waste water boils a...

Abstract

The invention discloses a sewage regeneration cycle treatment method and a system thereof. The system comprises a treatment unit for oil containing wastewater and a treatment unit for other industrialwastewater which are mutually contacted. The sewage regeneration cycle treatment method comprises the steps: adding a treating agent into wastewater, boiling and evaporating moisture in the wastewater through high temperature, performing filtering, flow dividing and cooling treatment on water vapor and collecting and utilizing waste oil which is left after dewatering. By means of the sewage regeneration cycle treatment method and the system thereof, oil containing wastewater and other industrial wastewater can be effectively treated, and water quality can reach IV water quality stated in Environmental Quality Standard for Surface Water (GB3838-2002). Water and oil in the oil containing wastewater can be effectively separated, waste is turned into wealth, and the separated waste oil can beutilized again; a treatment scale is larger; no new pollution sources is generated when the wastewater is treated; waste oil steam and other impurities generated in treatment can service fuel of a heating furnace to be used; meanwhile, the system has a high heat utilization efficiency, and energy consumption cost for treating every ton of wastewater is only 20 yuan.

Description

technical field [0001] The invention relates to a sewage treatment system. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment can be divided into three types according to its function: physical method, biological method and chemical method. According to the degree of treatment, in the prior art, the chemical treatment method has a better treatment effect, and the treatment degree of the biological method is higher than that of the physical method, and the physical method is often used in situations where the degree of water treatment is not high. However, the cost of biological and chemical methods is high, the treatment capacity is small, and the quality of effluent water is still difficult to meet the requirements. Especially in the prior art, only domestic wastewater can be treated on a large scale, while the large-scale treatment of o...
