Environment-friendly domestic sewage treatment device

Abstract

The invention discloses an environment-friendly domestic sewage treatment device which comprises a treatment box and a sewage inlet. A sewage inlet pipe is arranged on the lower side of the sewage inlet. Inclination plates which partitions one side of the treatment box to form a triangular water storage bin are arranged in the treatment box. The sewage inlet pipe extends into the triangular waterstorage bin. Installation grooves are formed in the outer sides of the inclination plates. A pull-type positioning plate is arranged between the treatment box and the installation grooves. The positioning plate, the inclination plates and the inner side of the treatment box are matched to form an oil storage bin. An oil outlet running through the oil storage bin is formed above the inclination plates. A treatment basket communicated with the triangular water storage bin and capable of horizontally moving is arranged in the treatment box. A filter screen controlled by a motor is hinged to the lower portion of the treatment box. Partition plates for dividing the two sides of the lower side of the treatment box into a sewage treatment bin and an impurity collection bin are arranged on the lower side of the filter screen. A high-pressure nozzle which is driven by a water suction pump and pumps back water of the sewage treatment bin to flush the filter screen is arranged on the impurity collection bin. The environment-friendly domestic sewage treatment device improves the treatment effect, saves energy and protects the environment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more particularly, to an environmental protection domestic sewage treatment equipment. Background technique [0002] Domestic sewage is the waste water discharged from the daily life of residents, which refers to the complex mixture of various forms of inorganic and organic substances, including: ① floating and suspended solid particles; ② colloidal and gel-like diffusers; ③ pure solution. It mainly comes from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and bathrooms of industrial enterprises. The domestic sewage is the sewage produced in daily life. The pollutants contained in the domestic sewage are mainly organic matter (such as protein, carbohydrate, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infection viruses, etc.) . The orga...

Problems solved by technology

[0003] For the current domestic sewage treatment, most of the treatment methods are not thorough enough to meet the sewage treatment discharge standards, so there are problems of waste of water resources and pollution of the environment, and there will be debris in the process of sewage filtration and treatment. Therefore, in order to solve such problems, someone designed an energy-saving and environment-friendly domestic sewage treatment device. The patent number is: 201711219266.5. The top of the treatment box is fixedly connected with a first push rod motor on the side away from the water inlet, the output shaft of the first push rod motor passes through the top of the treatment box and is fixedly connected with a connecting rod, and the inner wall of the treatment box is fixedly connected with a second A sieve and a second sieve, the second sieve is located below the first sieve, the outer wall of one side of the processing box is fixedly connected with the first mounting plate and the second mounting plate, the second mounting plate is located below the first mounting plate , the top of the first mounting plate is provided with a second push rod motor, the output shaft of the second push rod motor passes through the side wall of the processing box and is fixedly connected with the first push rod, and the first push rod is rollingly connected with a rotating roller. The invention mainly uses the design of the first push rod motor, the connecting rod, the roller, the rotating roller, the second push rod motor, the first push plate, and the first screen to initially remove impurities from the domestic sewage, and also to remove the impurities adsorbed at the second stage. The sundries on the first screen are thoroughly treated, and the design of the third push rod motor, the second push plate, and the second screen can further remove impurities from the domestic sewage, and collect them through the sundry collection box, and pass through the activated carbon adsorption layer The design of the invention plus the introduction of microorganisms from the water inlet can carry out deep cleaning of sewage and improve water quality. The present invention can effectively purify domestic sewage and remove impurities from sewage treatment equipment, but although the structure It can remove impurities, but because some impurities will remain on the filter when the push rod is pushed, there will be residual impurities on the filter. Once the time is long, the accumulation of impurities will easily lead to poor filtering effect. The sewage treatment effect of this kind of sewage is poor, and the oil will remain on the filter net. After a long time of use, it will accumulate on the filter net with residual impurities and oil, and oil stains will remain after sewage treatment, which will eventually lead to poor sewage treatment effect. In addition, the environmental protection of this structure The effect is not good, so we put forward an improvement and designed a domestic sewage treatment equipment for environmental protection
