What Is a Septic Tank Riser?

A septic tank (huàfènchí) is a device that treats faeces and filters the sediment. The principle is that the solidified material decomposes at the bottom of the pond, and the upper layer of hydrated objects enters the pipe and flows away, preventing the pipeline from being blocked and giving the solidified objects (manure and other garbage) sufficient time to hydrolyze. A septic tank refers to a small-scale treatment structure that separates domestic sewage into sediments and performs anaerobic digestion of sludge. ^[1]

The septic tank is a treatment equipment for removing suspended organic matter in domestic sewage by using the principle of precipitation and anaerobic fermentation. There is a partition inside the high-efficiency corrugated glass septic tank. The holes on the partition are misaligned up and down, which makes it difficult to form a short flow. The bottom of the first and second anaerobic chambers communicate with each other, and "MDS special packing" is added inside. Such separation reduces the contact time between sewage and sludge, so that the two processes of acidic fermentation and alkaline fermentation do not interfere with each other. At the same time, the presence of filler increases the contact surface area of sewage sludge and anaerobic bacteria, and greatly improves the reaction efficiency. ^[4]

As a traditional environmental protection facility with a history of more than 100 years, septic tanks have played an important role. However, with the progress of society and the development of urban modernization, problems that deviate from social development have also emerged, which need to be resolved urgently, mainly as follows:

Domestic sewage is becoming more and more serious for environmental pollution. Based on the introduction of foreign domestic sewage treatment technology, combined with scientific research results and engineering practices, this product uses polymer composite materials and factory production. It is an efficient, energy-saving, lightweight, Cheap domestic sewage treatment equipment. It successfully replaced the traditional brick and steel concrete septic tanks due to leakage and poor operating conditions, which polluted the groundwater quality and affected the safety of surrounding buildings. This product uses the gravity flow of water, does not require any external power and operating costs, saves energy and is easy to manage. It has very good social, environmental and economic benefits. ^[1]
