Tail water treatment device for sewage plant and rural domestic wastewater

Abstract

The invention discloses a tail water treatment device for a sewage plant and rural domestic wastewater. The tail water treatment device is characterized by comprising a dosing device and a partition reactor, wherein the dosing device comprises a dosing tank and a dosing pump; the partition reactor is divided into a partition coagulation region, a reaction region, a settling region and a clarification region; six partitions and a water inlet are arranged in the partition coagulation region; the reaction region is connected with the partition coagulation region, the settling region and the clarification region; a sludge hopper is arranged in the settling region; a sewage discharging opening is formed in the left side of the sludge hopper; a water outlet is formed in the clarification region;the height of the water outlet is equal to that of the second partition. The tail water treatment device disclosed by the invention occupies a small area, is low in capital construction cost and lowin energy consumption, greatly reduces the tail water treatment cost of the sewage plant and the rural domestic wastewater, and is suitable for treating tail water of the sewage plant and the rural domestic wastewater.

Description

technical field [0001] The invention relates to the field of tail water treatment devices for sewage plants and rural domestic sewage, and specifically belongs to a tail water treatment device for sewage plants and rural domestic sewage. Background technique [0002] With the rapid development of my country's economic construction, the total population continues to rise, and the load of sewage treatment plants continues to rise. Due to the limitations of their own processes, individual indicators such as total phosphorus and total nitrogen in the effluent of sewage plants often fail to meet the first-level A discharge stipulated by the state. standard. With the continuous acceleration of new rural construction, the discharge of rural domestic sewage is gradually increasing, and the pollutant indicators of rural domestic sewage are also rising. Due to the imperfection of rural infrastructure facilities, the treatment process of domestic sewage is extremely simple or even has n...

AI Technical Summary

Problems solved by technology

[0003] Today's tail water treatment devices have the following problems: ① complex power distribution network is required, which increases the cost and energy consumption of tail water treatment; ② when the tail water enters the coagulation tank, large-scale stirring equipment is required to continuously stir to achieve the purpose of fully mixing the chemical agent and the tail water , and the addition of large-scale mixing equipment will increase the footprint of the tail water treatment device; ③The traditional tail water treatment device has high infrastructure costs, which is not conducive to rural construction
