Sewage treatment device

Abstract

The invention discloses a sewage treatment device which comprises a trash chamber and a purification box, wherein the trash chamber is provided with a trash chamber water inlet and a trash chamber water outlet; a first filtering net and a second filtering net below the first filtering net are arranged inside the trash chamber in an inclined manner; a first blow-down valve and a second blow-down valve are respectively arranged at the bottom ends of the first filtering net and the second filtering net; the trash chamber water outlet is connected with a purification box water inlet; the purification box is divided into three purification chambers, namely, a first purification chamber, a second purification chamber and a third purification chamber in sequence, through a first partitioning plate and a second partitioning plate; rotating nozzles are arranged at the upper parts of the first purification chamber and the second purification chamber; a purification box water outlet is formed in the bottom end of the third purification chamber. The sewage treatment device provided by the invention has the advantages that the structure is simple, a small space is occupied, the treatment time is shortened, the treatment effect is improved, the treatment cost is lowered, the effluent quality is improved, and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device. Background technique [0002] At present, the treatment of industrial wastewater and domestic water has become an important issue in the process of urban modernization. The commonly used sewage treatment methods can be divided into physical methods, chemical methods, biological methods and comprehensive methods according to their functions. In view of the variety of sewage The most common treatment method is the comprehensive method, but this treatment method takes a long time, has high operating costs, and consumes a lot of energy, and it is difficult to achieve the ideal treatment effect in the end. In addition, the current sewage treatment devices have various problems such as large land occupation, complex structure, long treatment time, poor treatment effect, high treatment cost and poor effluent quality, making it difficult to meet the growing dema...
