Novel efficient energy-saving wastewater treatment device and use method thereof

Abstract

The invention discloses a novel efficient energy-saving wastewater treatment device and a using method thereof.The novel efficient energy-saving wastewater treatment device comprises a wastewater storage tank, one end of the wastewater storage tank is connected with an adjusting tank body, one end of the adjusting tank body is connected with a pH pre-adjusting tank body, one end of the pH pre-adjusting tank body is connected with a first reaction tank, and one end of the first reaction tank is connected with a first flocculation tank. According to the novel high-efficiency energy-saving wastewater treatment device and the using method thereof, a precipitated sludge reflux process is set, chemicals in sludge react with wastewater to form denser crystal particles, so that sludge reduction is realized, a channel is arranged for water supply through a circulating pipe in the process through hydraulic fine adjustment, the device has the advantages of being easy to clean and maintain and not prone to being blocked, a high pressure diaphragm dehydrator is used, the water content of sludge subjected to filter pressing of the dehydrator can reach about 70% at least, the water content of the sludge subjected to filter pressing of a common box type dehydrator reaches 80%, and the treatment load of a follow-up dryer is reduced.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a novel high-efficiency and energy-saving wastewater treatment device and a method for using the same. Background technique [0002] The high-efficiency and energy-saving wastewater treatment device is a supporting equipment for wastewater treatment. In industrial production, a certain amount of wastewater will be generated. The daily wastewater production volume is 400m3 / d. Considering the unevenness of drainage, the designed treatment capacity is 16m3 / d h. During the sewage treatment process, a certain amount of sludge will be produced, which needs to be treated regularly. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of high-efficiency and energy-saving wastewater treatment devices. [0003] The existing high-efficiency and energy-saving wastewater treatment devices have certain disadvanta...

AI Technical Summary

Problems solved by technology

[0003] The existing high-efficiency and energy-saving wastewater treatment devices have certain disadvantages in use. First, the sludge removal operation cannot be carried out well. The sludge contains harmful substances such as bacteria, pathogenic organisms, and parasite eggs, and the sludge is very unstable. It needs to be processed and disposed of in time, which is not conducive to people's use. In addition, it is prone to lime waste, cannot be cleaned and maintained well, and is prone to blockage, which has brought certain adverse effects to people's use process. Therefore, we propose a new type of high-efficiency and energy-saving wastewater treatment device and its application method
