Multiphase circulation integrated sewage treatment equipment

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...

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
