Cangzhou Livestock Manure Storage – Odor Control (MW-UV)

Cangzhou Livestock Manure Storage project equipment

Project Overview

Pig breeding base: manure holding tanks and a small composting shed. Design air volume: 6,800 m3/h.

Odor Components

Ammonia, hydrogen sulfide, indole and skatole

Operating Challenges

Multiple odor points treatable as independent zones; intermittent odor generation; site is off the main road but close to villages.

Treatment Process

Enclosure negative-pressure collection → water scrubber pretreatment → MW-UV catalytic oxidation unit, with spatial atomization deodorization as auxiliary suppression

Main Equipment

Corrosion-resistant fan, scrubber tower, MW-UV oxidation unit, botanical liquid atomization unit

Treatment Results

Boundary manure odor markedly reduced; no odor spread to surrounding farmland or villages.

Operating Cost

0.50–0.59 CNY / 1,000 m3 of exhaust gas

Technical Highlights

Zoned independent treatment; MW-UV + botanical atomization combination balances treatment efficiency with in-zone odor suppression.

This project uses a Microwave UV Oxidation combined process. Learn more about the technology on our Microwave UV Oxidation equipment page. For a similar design, contact us at s18301170098@gmail.com / WhatsApp +86 19833770783.

Engineering Approach

Odor-control retrofits begin with capture: hoods and duct routing are arranged so the fan sees the lowest practical excess air, then the treatment stage – low-temperature plasma or microwave-UV – is sized against the measured or estimated pollutant spectrum and the intermittent profile of generation.

System Composition

A standard package comprises pretreatment (demisting/filtration where humidity or droplets are present), the oxidation stage with multiple modular trains, induced-draft fan, stack, and a control cabinet with interlocked start-up so the treatment unit always runs before the extraction fan ramps.

After-Sales

Modularity keeps maintenance predictable: individual trains isolate electrically for service without stopping the line. Consumables are limited to filters and periodic lamp/electrode inspection – both items stocked for quick dispatch.
