Problems solved by technology

[0002] Now, the treatment of new rural sewage purification tanks has been widely used in rural China. The conventional design can generally be divided into two-compartment septic tanks or three-compartment septic tanks. Conventional septic tanks have many disadvantages, and new rural areas are using them In conventional septic tank sewage treatment, when the pipeline is aged and blocked, the activated sludge will not be able to supply the crops. In the case of connected pipelines, the conventionally used two-compartment septic tank or three-compartment septic tank does not play a role in detoxification. Nitrogen and phosphorus removal effect, but directly discharged, which caused river pollution
[0003] In addition, the traditional simple septic tank treatment technology is prone to clogging, making it impossible to achieve the first-level A effect of total nitrogen and total phosphorus, which also brings many difficulties to the environmental pollution control of China's new rural areas

Embodiment 1

[0018] Embodiment 1: A new rural domestic sewage denitrification and phosphorus removal purification system, including rural domestic sewage head 17, a septic tank connected to the sewage pipe of the rural domestic sewage head 17 and an outlet pipe 18 connected to the septic tank, each Each rural domestic sewage household head 17 is connected to a septic tank correspondingly, and a septic tank 19 is added behind the septic tank, and all septic tanks are connected in parallel and connected to a septic tank 19 in a unified manner, the septic tank 19 is connected to the outlet pipe 18, and the septic tank 19 is provided with return pipeline and connects septic tank. The purification tank 19 includes a sealed tank body, which is divided into an anaerobic zone, an aerobic zone, an aeration zone, and a reflux zone, and a reflux pipe is set in the reflux zone to connect the anaerobic zone.

[0019] The septic tank includes a horizontal shell 1, a water inlet 1.1 opened at the left en...

Embodiment 2

[0020] Embodiment 2: With reference to Example 1, an auxiliary partition 14 is arranged in the anaerobic zone 3 of the septic tank, and the anaerobic zone 3 is divided into an anaerobic I zone 15 and an anaerobic II zone 16. Near the top of the plate 14, there are feces openings 14.1, the air lift automatic feces discharge device 6 is set in the anaerobic II zone 16, and the return pipe 7.2 of the mixed liquid gas lift device 7 extends into the anaerobic I zone 15 , and in the anaerobic II zone 16, and are all provided with a return port 7.2.1.

[0021] In the above embodiment 1 or 2, the rotary flow regulator 11 includes a top-sealed inner liner 11.1, a rotary sleeve 11.2 sleeved on the inner liner 11.1, a connecting joint 11.3 arranged at the bottom end of the inner liner 11.1, (the connecting joint Hoops can be used) The side wall of the inner liner 11.1 is provided with a water outlet hole 11.1.1, and the side wall of the rotating sleeve 11.2 is provided with an adjustment...

Abstract

The invention relates to a new rural domestic sewage nitrogen and phosphorus removal purification system. The system includes rural domestic sewage householders, septic tanks in corresponding connection with rural domestic sewage householders' sewage pipes and a water outlet pipe connected to the septic tanks. Every rural domestic sewage householder is connected to a septic tank correspondingly, a purification tank is additionally disposed behind the septic tanks, all the septic tanks are in parallel connection, and are gathered and then connected to the purification tank, the purification tank is connected to the water outlet pipe, and the purification tank is equipped with a reflux pipeline connected to the septic tanks. The septic tanks and purification tank are employed to realize rural sewage treatment, and achieve a two-stage biological treatment effect. A high activated sludge concentration is maintained, the purification tank is free of blockage, collection and gathering of scattered household sewage for co-treatment can be realized, and the sewage treatment reaches the effect of first level A of total nitrogen and total phosphorus. Aerobic activated sludge particles are utilized for synchronous realization of nitrification and denitrification effects.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, in particular to the improvement and upgrading of two-compartment septic tanks and three-compartment septic tanks in rural sewage treatment. Background technique [0002] Now, the treatment of new rural sewage purification tanks has been widely used in rural China. The conventional design can generally be divided into two-compartment septic tanks or three-compartment septic tanks. Conventional septic tanks have many disadvantages, and new rural areas are using them In conventional septic tank sewage treatment, when the pipeline is aged and blocked, the activated sludge will not be able to supply the crops. In the case of connected pipelines, the conventionally used two-compartment septic tank or three-compartment septic tank does not play a role in detoxification. The effect of nitrogen and phosphorus removal, but directly discharged, thus causing river poll...
