Improved floating biochemical sewage treatment equipment and method thereof

Abstract

The invention relates to improved floating biochemical sewage treatment equipment and a method thereof. The improved floating biochemical sewage treatment equipment comprises a water inlet distribution channel, an anoxic reaction zone, an aerobic reaction zone, an internal reflux equipment zone, a water outlet zone and a valve well, the water inlet distribution channel is used as an anaerobic reaction area; the water inlet pipe and the return sludge pipe are respectively connected with the inlet water distribution channel, the water inlet distribution channel is connected with the anoxic reaction zone through a gate, the anoxic reaction zone is provided with a submersible stirrer, the anoxic reaction zone is connected with the aerobic reaction zone through a water passing hole, the aerobicreaction zone is connected with the internal reflux equipment zone through a water passing hole, the internal reflux equipment zone is connected with the water outlet zone through a gate, and the water outlet zone is connected with a water outlet pipe. The sewage treatment equipment has the beneficial effects that the wing-shaped filler is arranged in the aerobic tank, so that the concentration of activated sludge is increased, the microbial population is rich, the volume load is high, the impact load resistance is high, the sewage treatment efficiency is improved, a primary sedimentation tank is not arranged, and the occupied area is small.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an improved floating biochemical sewage treatment equipment and method thereof. Background technique [0002] On April 16, 2015, the "Water Pollution Prevention and Control Action Plan" called for strengthening urban domestic pollution control. Accelerate the construction and renovation of urban sewage treatment facilities. Existing urban sewage treatment facilities should be remodeled according to local conditions and meet the corresponding discharge standards or recycling requirements by the end of 2020. Urban sewage treatment facilities in sensitive areas (key lakes, key reservoirs, and coastal water catchment areas) should fully meet the Class A discharge standard by the end of 2017. For cities where the water quality in the built-up area does not meet the Class IV standard for surface water, the new urban sewage treatment facilities must implement Class A discharge standard...

Problems solved by technology

[0004] However, due to the problems of high investment, high power consumption and high operating costs in the use of urban sewage treatment facilities, it is not suitable for the development status of small towns and rural areas in my country; Due to the imperfect treatment process and technology, the treatment efficiency is low and the effect is poor, and it cannot meet the increasingly stringent water quality indicators of the country; in addition, because it is buried, the construction is complicated, and the maintenance and maintenance are difficult, resulting in many being abandoned.
