Problems solved by technology

[0006] Therefore, the sludge formed after the treatment of rural sewage will contain more organic matter. During the subsequent sludge landfill process, the anaerobic fermentation of organic matter will generate a large amount of gas, resulting in the instability of the sludge and affecting the follow-up treatment. Create trouble
At the same time, the sludge with high organic content has a large volume and weight, resulting in a large amount of sludge produced in the sewage treatment process, which increases the cost of cleaning and transportation

Embodiment Construction

[0034] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0035] like figure 1 As shown, the multiphase circulation integrated sewage treatment equipment includes: an oil separation septic tank 10 ; a multiphase circulation biological pool 20 , and a vertical fiber cloth filter tank 30 .

[0036] like figure 1 and figure 2 As shown, the oil-separating septic tank 10 is a three-stage type, and there is an H-shaped water passage 11 between adjacent two sections. Since oil is lighter than water, oil stains will float on the upper layer of sewage, and the water passage 11 The lower end is immersed in the water layer, so only water can enter the next oil separation septic tank through the H-shaped water passage. The oil-separation septic tank 10 performs oil-water isolation, particle sedimentation and anaerobic fermentation.

[0037] In the last section of the oil-separating septic tank 10 , at ...

Abstract

The invention provides multiphase circulation integrated sewage treatment equipment. The equipment is characterized by comprising an oil-separating septic tank, a multiphase circulation biological tank and a vertical fiber cloth filter, wherein the oil-separating septic tank, the multiphase circulation biological tank and the vertical fiber cloth filter are arranged in sequence, the multiphase circulation biological tank is provided with an umbrella aeration gas stripping device and corrugated biological stuffing, a gap is reserved between the corrugated biological stuffing and the bottom of the multiphase circulation biological tank, the umbrella aeration gas stripping device is provided with a gas stripping pipe and an umbrella aeration head, the umbrella aeration head is arranged above the corrugated biological stuffing, and the gas stripping pipe penetrates through the corrugated biological stuffing and reaches the gap below the corrugated biological stuffing for fetching water. According to the multiphase circulation integrated sewage treatment equipment, by the adoption of the multiphase circulation biological tank, sewage treatment efficiency is greatly improved.

Description

technical field [0001] The invention relates to multiphase circulation integrated sewage treatment equipment, which belongs to the field of sewage treatment. Background technique [0002] With the rapid development of the economy, the problem of rural environmental pollution has become increasingly prominent. The amount of major pollutants produced in my country's rural areas has accounted for half of the country's total. In terms of domestic sewage treatment, about 8 billion tons of domestic sewage are produced in rural areas of the country every year, and 96% of the villages do not have drainage channels and sewage treatment systems, and domestic sewage is discharged randomly. The wanton discharge of untreated domestic sewage seriously pollutes the rural ecological environment and directly threatens the health of farmers and the economic development of rural areas. [0003] At present, the sewage treatment system in some villages has not been established, and the collect...
