Unstable treatment effect: Because the quality and quantity of farm sewage vary greatly, it may be difficult for treatment equipment to maintain consistent treatment effect under different conditions. This may lead to the problem that the effluent quality is not up to standard or the treatment effect is unstable.

Difficulties in equipment selection: Farmhouses are usually small in scale and have different requirements for sewage treatment equipment. However, the sewage treatment equipment mainly provided in the market is usually suitable for large or medium-sized treatment systems and cannot meet the actual needs of farmhouse music. Therefore, it may be difficult to select a suitable device.

High operation and maintenance costs: Farmhouses usually have low requirements for equipment operation costs and maintenance manpower. However, the operation and maintenance costs of some sewage treatment equipment in the market are high, including energy consumption, chemical dosing and equipment maintenance. This may increase the economic burden of farmhouse operators.

Imperfect technical support and after-sales service: Some suppliers of sewage treatment equipment in the market have shortcomings in technical support and after-sales service. Farm operators may face difficulties in obtaining timely and professional technical support and solving equipment operation problems.

Complexity of treatment process: Some efficient sewage treatment processes have certain complexity in technical realization and operation, and have higher requirements for operators. Farmhouse operators may lack corresponding technical training and operation guidance, which makes the operation and maintenance of processing equipment more difficult.
