Embodiment Construction

[0008] The working process and principle are as follows: the sewage enters the hydrolysis acidification tank through the sewage inlet pipe (1), and is disturbed by the deflector flap (3) and the spoiler wing (4), which increases the turbulence of the water flow and improves the phase mass transfer, so that the sewage in the sewage Organic pollutants are efficiently removed under the action of hydrolysis and acidification bacteria in the pool, and then enter the high-efficiency three-phase separation area through the perforated flower wall (5), the water flow is clarified by the high-efficiency inclined plate sedimentation equipment (6), and the water is collected by the sump (7). Finally, it is discharged from the outlet pipe (8); the solid-phase pollutants and anaerobic bacteria in the water flow are accumulated in the mud storage hopper (9) after being separated by high-efficiency inclined plate sedimentation equipment or settled along the way, and can be discharged by the mud...

Abstract

The invention provides an efficient composite hydrolysis acidification pool having both waste water treatment and sludge reduction function, which belongs to an environmental protection device technology field and relates to improvement of the process and device for waste water treatment.Large energy consumption and high operation cost have handicapped the construction and operation of sewage plants in our country for a long time.The sludge is a byproduct of waste water treatment. The sludge disposal charge takes one third of the operation cost in the sewage plant, and the solid waste secondary pollutant is caused at the same time.In order to solve the problem, the invention provides an efficient hydrolysis acidification technique for the sludge reducing and the synchronous processing of waste water and solid pollutants. Due to the invention, a primary sedimentation pond is replaced, interception efficiency of suspended substance is strengthened, returning excess sludge is hydrolysis liquefied; meanwhile, the reduction processing of solid waste and sludge is achieved.The invention also increases turbulent flow and mass transfer by the arrangement of folding and wing panel in the pool to strengthen the removal rate of hydrolysis acidification pool on dissolved organic pollutants.

Description

technical field [0001] The patent of the invention belongs to the technical field of environmental protection equipment and relates to an improvement of sewage treatment process equipment. Background technique [0002] Wastewater treatment is an energy-intensive integrated technology. For a long time, high energy consumption and high operating costs have hindered the construction and operation of urban sewage treatment plants in my country to a certain extent. Investigations and studies have shown that the energy consumption of urban sewage treatment plants in my country is mainly used for oxygen supply in biological treatment and sludge treatment, accounting for more than 60% of the direct operating costs of sewage plants. [0003] Sludge is a by-product of sewage treatment. Calculated with a water content of 97%, the volume accounts for 0.3-0.5% of the treated sewage, and the amount of sludge produced by advanced treatment will further increase. At present, the annual di...
