Combined sewage treatment device

Abstract

The invention discloses a combined type sewage treatment apparatus, which comprises an integrated grid-shaped sewage filter component formed through assembled connection of a plurality of sewage treatment primitive boards. The outer contour of the filter component is adapted to the shape and the size of a cross-section of flowing water of the sewage so as to determine the shapes and the number ofthe selected sewage treatment primitive boards. Each sewage treatment primitive board comprises a cage for filling with a water treatment adsorbent, wherein a unit frame and two cover plates with meshes are actively assembled into the cage. With the meshes in the cover plate, the water treatment adsorbent in the cage can be prevented from loss. The shapes and the number of the sewage treatment primitive boards can be adjusted freely, such that the size of the sewage treatment apparatus can be adapted to a sewage treatment system requiring treatment. The sewage treatment primitive boards are easy to be disassembled and assembled, such that the water treatment adsorbent can be reused so as to reduce the secondary pollution. The apparatus provided by the present invention has characteristicsof simple structure, convenient operation, low cost, strong applicability and good size adjustability, and can be applicable for various sewage treatment systems.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a combined sewage treatment device which is convenient for disassembly and assembly, and belongs to the technical field of industrial and domestic waste water treatment. Background technique [0002] In recent years, my country's water pollution accidents have occurred frequently. In November 2005, the Songhua River was polluted by nitrobenzene; in December 2005, an explosion occurred in the Dianjiang River in Chongqing City, which caused the leakage of benzene series, causing Xinmin Guixi River, Caojia River, etc. River pollution; at the end of 2005 and early 2006, cadmium pollution occurred in the Beijiang River of Guangdong and the Xiangjiang River of Hunan Province; at the end of May 2007, a blue-green algae crisis broke out in Taihu Lake. In 2005, the National People's Congress Standing Committee's Water Pollution Prevention and Control Law Enforcement Inspection Team found that a...

Problems solved by technology

[0005] Although all kinds of adsorption and separation materials have made important research progress, their practical progress is relatively slow. In the treatment of some water pollution, a large number of materials have not been practically constructed, and are directly dumped into sewage for adsorption. The efficient utilization and recovery of adsorbent materials have brought great difficulties, especially in the purification treatment of river sewage, there is no sewage treatment device that is easy to operate and low in cost, and there are also problems in the recovery means of water treatment adsorbents. question

Facing the increasingly severe water pollution problem, there is still no effective way and device to purify it
