Wastewater Deodorization Project of Zhongke Gengjiu Hospital in Hefei City, Anhui Province_The pharmaceutical and medical industryCase-Eclear Environmental

PROJECT OVERVIEW

Anhui Zhongke Gengjiu Hospital is a provincial-level comprehensive hospital approved by the Anhui Provincial Health Commission, which integrates first aid, prevention, medical treatment, teaching, and scientific research. The hospital is located at No. 999 Huayuan Avenue, Baohe District (southeast corner of the intersection of Huizhou Avenue and Huayuan Avenue, next to Exit C of Gaowang Station on Hefei Metro Line 1). The total investment of the first phase of the hospital project is 1.6 billion yuan, with a construction area of 162000 square meters. It is planned to open 1200 beds, and currently 500 beds are open. The hospital started operating on December 26, 2021, and is a designated hospital for medical insurance for provincial and municipal employees, as well as urban and rural residents. It has also achieved direct settlement for cross provincial and cross regional medical treatment nationwide. In January 2022, the hospital was officially authorized to become the Clinical College of Anhui Medical University, and has signed medical consortium cooperation agreements with well-known tertiary hospitals in the province, such as the First Affiliated Hospital of the University of Science and Technology of China (Anhui Provincial Hospital), Anhui Cancer Hospital, and the First Affiliated Hospital of Anhui Medical University. In March 2023, the hospital officially joined the China-Japan Friendship Hospital National Telemedicine and Internet Diagnosis and Treatment Center, and became an alliance unit of "National Integrated Chinese and Western Medicine Diagnosis and Treatment Center". In December 2023, the hospital signed a strategic cooperation agreement with Anhui University of Traditional Chinese Medicine.

PROJECT INTRODUCTION

ECLEAR SOLUTION

Design air volume

5,500m³/h

Design process

YQWT spray washing+YQD biofilter process

Pre washing system

After being collected, the exhaust gas enters the pre-treatment stage through pipelines, and the alkaline/acidic gases in the exhaust gas are neutralized and washed using acid/alkaline solution.

Biological reaction system

The pre-treatment waste gas passes through the packing from the bottom of the bioreactor system from bottom to top, and the foul odor gas is transferred from the gas phase to the water microbial mixed phase, which is decomposed by the microbial metabolism fixed on the filter material.

Exhaust emission system

Choose as needed, consisting of explosion-proof fans and high-altitude discharge pipelines to achieve exhaust gas emission standards and emission heights.

COMPLIANCE REQUIREMENT

Odor components	Odor inlet indicators	Odor discharge indicators	Exhaust pipe height
H2S	≤100mg/m3	≤0.6kg/h	15m
NH3	≤40mg/m3	≤0.6kg/h
C2H6S	≤50mg/m3	≤0.6kg/h

Eclear Environmental RELATED EQUIPMENT

Spray tower

Spray tower, as a type of environmental waste gas treatment equipment, exists. According to its working principle, it can be divided into circulating water spray tower, alkali spray tower, and acid spray tower (also known as acid washing tower). According to the material of the tower, it is divided into fiberglass spray towers, PP spray towers, and stainless steel spray towers. Choose a reasonable spray material and spray process based on the different properties of the exhaust gas. Spray tower is an important industrial waste gas treatment equipment, whose working principle is to use water and power technology to spray liquid or gas in a mist form into the waste gas, in order to remove harmful substances in the waste gas.

Biological filter

A biological filter is a device that uses effective deodorizing bacteria and a reasonable equipment structure to oxidize and decompose large molecules or structurally complex organic matter into simple inorganic substances such as water and carbon dioxide through differentiation. Eclear Environmental Biological Filter has been improved compared to its peers, adopting an integrated treatment process of pre-treatment and deep adsorption of biological treatment to ensure the stability of the intake during the biological treatment stage. At the same time, deep treatment is not configured at the end, which can ensure that the exhaust gas meets the standard when the emission concentration exceeds the design.

Biological strains

Eclear uses specialized composite bacterial strains, including methane producing bacteria, actinomycetes, Bacillus, yeast, and other bacterial strains, which can target the treatment of odorous components such as hydrogen sulfide, ammonia, and VOCs. Adopting a combination of heterotrophic and autotrophic bacteria, according to the composition of exhaust gas, the microbial composition is reasonably proportioned, taking into account the treatment of organic and inorganic pollutants. Microbial strains have high purity, fast biofilm formation, high activity, and high treatment efficiency, which have significant advantages compared to conventional single strains. Combined with biological enzyme products, it effectively and gently catalyzes the decomposition of pollutants by microorganisms, making their decomposition more targeted and achieving better treatment results for odor pollutants.

Washing tower

Washing tower is a mature waste gas treatment equipment widely used in pre-treatment of industrial waste gas treatment, dust removal, and other aspects. Gas enters the tower and fully contacts, adsorbs, and dissolves with the washing liquid inside the tower, achieving purification effect. The design forms of Yi cleaning towers are diverse, and vertical or horizontal structures can be used according to the project application site. The commonly used materials for washing tower equipment include PP, FRP, and stainless steel. PP and FRP are commonly used in chemical absorption towers and have the characteristics of acid resistance, alkali resistance, and corrosion resistance. Stainless steel materials can be used for high-temperature exhaust gas.
