Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] figure 1 The shown deodorizing device is connected on the well cover 4, and two or four holes 3 are generally set on the well cover 4 (sometimes not provided). The deodorizing device is mainly composed of a deodorizing part 5 and a container 1; the deodorizing part 5 can be a biological filter material filling layer, an adsorbent filling layer, an oxidant and its carrier filling layer, a discharge ozone reactor, etc.; 1. A number of small holes 2 are set. The size of the small holes 2 is smaller than the size of the filter material. The container 1 can be made of non-metal such as plastic, glass fiber reinforced plastic or metal such as stainless steel; Bonding agent, etc. are connected to the well cover. Working principle: when the odor in the well rises to the deodorizing device, the odor components enter the deodorizing component 5 through several small h...

Abstract

An antiodoring cover for the sewage tank or septic tank is composed of a cover body and an antiodoring unit under the cover body. Said antiodoring unit is prepared from activated carbon, molecular sieve, hoolamite and diatomite. The filter method, adsorptive method, chemical oxidizing method, or discharging ozone oxidizing method can be used.

Description

technical field [0001] The present invention relates to the improvement of manhole covers. Background technique [0002] In the prior art, some improvements of well covers are mainly in aspects such as cost reduction, anti-theft, and sealing, such as patents such as CN97216742, CN01259531, and CN03226716. Deodorization measures were not considered. Especially for sewage well covers and septic tank covers, without deodorization measures, odors often escape and pollute the environment. [0003] There are many methods for deodorization and deodorization in other fields, such as biological filter material filtration method, adsorption method such as activated carbon, molecular sieve, pumice stone, diatomaceous earth, chemical oxidation method (chemical reduction method), discharge ozone oxidation method, etc. Contents of the invention [0004] The purpose of the present invention is to provide a well cover deodorization device. [0005] A well cover deodorizing device for r...
