COMPOSITION OF LIVESTOCK WASTE WATER
Cleaning the cage with water has generated a large amount of wastewater. Wastewater is mainly from pig bathing and cleaning of the barn including: feces, urine, and water for cleaning the barn.
Characteristics of pig production waste
The amount of manure and urine excreted in a day and night depends on the breed, species, age, feed rations, and weight of cattle. Pig manure is classified as liquid manure, water content accounts for 56-83%, the rest is dry matter including organic substances, NPK compounds in the form of inorganic substances.
Based on the experience of construction works and the results of wastewater analysis of the farms in the South and the North, the characteristics of pig farming wastewater (depending on whether the system is separated or not) has the following components: part as follows:

TECHNOLOGY CHART OF WASTE WATER TREATMENT SYSTEM LIVESTOCK LIVESTOCK
Biogas recovery wastewater treatment technology proposed by the Company ensures treatment efficiency, wastewater after treatment meets QCVN 62-2016/BTNMT standard.
The wastewater treatment company's system is operated automatically, in addition, there is a manual operation mode when there is a technical problem.
Biogas tanks / tunnels are researched and designed by Viet Water Company with specialized construction techniques to ensure thorough treatment of high pollution indicators.
The retention time of water in the biogas cellar is enough to effectively treat wastewater with large organic pollution, with this retention time will ensure the highest treatment efficiency.
In the Biogas Tunnel, under the influence of high-speed microbial products and the action of anaerobic microorganisms, the wastewater will ferment, reduce the content of pollutants in the wastewater, and at the same time generate biogas production. produce biogas back to production.
In addition, the biogas tunnels are also designed with systems to disturb the wastewater inside the tunnel, in order to avoid sedimentation and create the most favorable conditions for biogas (CH4) production.
The water after the treatment system will be stored into the biological pond for use for purposes such as irrigation, fish farming or discharge into the environment.

Currently, there are many methods of construction of livestock wastewater treatment systems. Depending on the actual situation at the enterprise, we have different system layouts. Viet Water would like to offer the most suitable construction method for the scale of the Farm, the wastewater flow is > 50m3/day.
With the characteristics of the farm scale, large wastewater flow, unlimited land area. The system of livestock wastewater treatment company will be designed with HDPE tarpaulin to save investment costs and be suitable for practical conditions.
Low initial investment cost.
Thoroughly handle pollution, creating a pollution-free, disease-free environment for farms and livestock establishments - ensuring hygiene standards for processing plants.
Biogas recovery is an active source of energy for on-site production.
Low operating and maintenance costs for the treatment system.
