Environment-friendly adjustable multi-layer sewage sampling device

Abstract

The invention discloses an environment-friendly adjustable multi-layer sewage sampling device. A sampling pipe is fixed on the side surface of a supporting plate; a first connecting plate and a secondconnecting plate are matched to connect the adjacent supporting plates; limiting plates are mounted at the top ends of the mounting holes; a connecting seat and a third connecting plate are matched to connect an adjacent connecting column; a return spring is sleeved on a mounting section; a cover plate is mounted on one side of the middle of the connecting column; a handle is fixed on the first connecting plate of the uppermost device body through a bolt; a pull plate is mounted in the middle of the handle; a pull ring is arranged in the middle of the upper surface of the pull plate. The multiple device bodies are sequentially connected up and down, the number of the device bodies can be adjusted according to the depth of the sewage pool and the sampling depth, and the sewage pools with different depths can be sampled and detected; and through a sampling pipe arranged on the device body, a worker can conveniently sample at multiple layers of water depths at the same time, a switch ofthe sampling pipe is controlled to be switched on and off through a grip, and the worker can conveniently use the device.

Description

Technical field [0001] The present invention belongs to the field of environmental protection equipment, particularly to a multi-layered environment protection sewage sampling device can be adjusted. Background technique [0002] The wastewater treatment processes are typically utilized or municipal wastewater discharge destination taking into account the natural purification capacity of water bodies, and to determine the extent of the respective sewage treatment process. Sewage, whether for industrial, agricultural or replenish groundwater recharge after processing, must comply with the relevant water quality standards issued by the state. [0003] Modern wastewater treatment technology, according to the degree of processing can be divided into primary, secondary and tertiary treatment processes. A sewage treatment applications physical methods such as screening, precipitation and removal of suspended solids floating substances insoluble in water. Secondary treatment of sewage b...

AI Technical Summary

Problems solved by technology

The tertiary treatment is advanced treatment, the effluent water quality is better, even can meet the drinking water quality standard, but the treatment cost is high, except in some countries and regions that are extremely short of water, it is rarely used

[0005] Sewage treatment plants often need to sample and test the sewage in the sewage tank. The existing sampling device can only sample and test a certain point in the sewage tank, and cannot realize multi-layer and layered sampling and detection.
