Embodiment Construction

[0014] now refer to figure 2 , which illustrates a method of organic waste treatment according to a non-limiting embodiment of the present invention. The method can be performed in a portable or non-portable system.

[0015] In step 201, a wastewater stream flows into the system. Waste can be, but not limited to, from animal processing or animal feed separation, such as cattle farms, dairy farms, chicken farms, pig farms, horse ranches, etc., manure from sewage flow tanks, human waste, etc. Waste can be transported by conventional pipes, pumps or other suitable techniques. Another example is a sewage or septic truck, which according to the invention may transport collected waste to the system (eg, the truck may be located in a city). The system may include surge tanks for temporary storage of waste from more than one such truck before the waste enters a settling tank in the process described below.

[0016] In step 202, the waste stream flows into a mixing and settling ta...

Abstract

A method of organic waste treatment includes treating an organic waste stream that contains solid waste particles suspended in a liquid to cause the solid waste particles to settle in a settling tank, separating contents of the tank into a separated liquid phase and a separated solid phase, and treating the separated solid phase with an oxidant to create a sterile odorless ash.

Description

technical field [0001] The present invention relates to a method for treating organic waste such as sewage sludge or animal excrement. Background technique [0002] There are many methods used to dispose of organic waste. For example, in waste sludge dewatering, waste sludge can be processed to obtain a dry product. Drying the product allows for a significant reduction in storage volume, ease of transport and, in the case of product incineration, reduced energy. Chemical conditioning can be used to facilitate dewatering of waste sludge. Conditioning may lead to flocculation of suspended particles in waste sludge. [0003] Typical prior art methods such as figure 1 shown. The wastewater stream is separated into a solids-rich fraction and a solids-lean fraction by a solids separation step (101). The separation step 101 may result in a solids-rich fraction comprising a high percentage (eg, 70% or more) of total suspended solids (TSS) from the wastewater. Total Suspended ...
